Abstract
The study sought to assess the procedural success of rotational atherectomy (RA) in coronary chronic total occlusion (CTO) and to investigate the in-hospital and one-year outcomes following RA. From 2015 to 2019, patients undergoing percutaneous coronary intervention for CTO (CTO PCI) were retrospectively included into the hospital database. The primary endpoint was procedural success. Secondary endpoints were in-hospital and one-year major adverse cardiovascular and cerebral event (MACCE) rates. During the study period of 5 years, 2.789 patients underwent CTO PCI. Patients treated with RA (n = 193, 6.92%) had a significantly higher procedural success (93.26% vs. 85.10%, p = 0.0002) compared to those treated without RA (n = 2.596, 93.08%). Despite a significantly higher rate of pericardiocentesis (3.11% vs. 0.50%, p = 0.0013) in the RA group, the in-hospital and one-year MACCE rate was similar in both groups (4.15% vs. 2.77%, p = 0.2612; 18.65% vs. 16.72%, p = 0.485). In conclusion, RA is associated with higher procedural success for CTO PCI, but has higher risks for pericardial tamponade than CTO PCI without the need for RA. Nevertheless, in-hospital and one-year MACCE rates did not differ in-between both groups.

Abstract
Creation of sizable subintima during intervention for chronic total occlusions (CTO) could lead to the key selection preference of metallic stents rather than bioresorbable vascular scaffolds (BVS) and then possibly deviate the outcome comparisons in real-world studies. By including recanalized CTO with true lumen tracking, we tested if any selection preference remained and compared the outcomes between everolimus-eluting stent (EES) and BVS implantation.Among 211 consecutive CTO interventions with true lumen tracking from August 2014 to April 2018 when BVS was available, we compared the clinical and interventional features between 28 patients with BVS and 77 patients with EES implantation. With propensity score matching and a median follow-up of 50.5 (37.3-60.3) months, we further assessed 25 patients with BVS and 25 with EES for target vessel failure (TVF: cardiac death, target vessel myocardial infarction, and target lesion revascularization).Multivariate analyses showed that BVS was still favored in the presence of LAD CTO (odds ratio (OR) = 3.4, 95% confidence interval (CI) = 1.0-11.7) and an average scaffold/stent size ≥ 3 mm (OR = 10.5, 95% CI = 3.0-37.3). EES was preferred for lesions with a J-CTO score ≥ 3 (OR = 19.3, 95% CI = 3.4-110.8) and multivessel intervention necessary at index procedure (OR = 11.3, 95% CI = 1.9-67.3). With matched comparisons, the TVF-free survival of EES was better than that of BVS for CTO recanalization (P = 0.049 by log-rank test) at long-term follow-up.Even with true lumen tracking techniques, selection bias remained substantial when determining either device for CTO implantation. The matched comparison of outcomes suggested the unfavorable longer-term impacts of the first generation of BVS on CTO lesions.

Abstract
OBJECTIVE This study aimed to assess the effects of coronary collateral circulation (CCC) on the prognosis of patients with chronic total occlusion (CTO) under different treatment strategies. METHODS We analyzed a total of 1124 patients who were diagnosed with CTO and divided them into groups with good CCC (grade 2 to 3, n = 539) or poor CCC (grade 0 to 1, n = 531). The primary outcome was cardiac death during follow-up; the secondary outcome was major adverse cardiovascular events (MACEs). We also performed subgroup analyses in groups with and without CTO revascularization (CTO-R and CTO-NR, respectively), and sensitivity analyses excluding patients who received failed CTO-PCI to further investigate the effect of CCC. RESULTS During a median follow-up duration of 23 months, we did not detect any significant differences between the good CCC group and the poor CCC group in terms of cardiac death (4.2% vs 4.1%; adjusted hazard ratio [HR], 1.01; 95% confidence interval [CI], 0.56-1.83; p = 0.970) and MACEs (23.6% vs 23.2%; adjusted HR, 1.07; 95% CI, 0.84-1.37; p = 0.590). Subgroup analyses according to CTO revascularization showed similar results. In addition, we observed no differences in sensitivity analyses when patients who received failed CTO-PCI were excluded. CONCLUSION Good CCC was not associated with a lower risk of cardiac death or MACEs among patients with CTO, regardless of whether the patients received CTO revascularization treatment.

Abstract
Diabetes mellitus (DM) is a substantial risk factor in developing coronary artery disease (CAD), coronary chronic total occlusion (CTO) lesions are discovering 10-35% in patients who underwent coronary angiography. This study compares the long-term clinical outcomes of two treatment strategies, percutaneous coronary intervention (PCI) with complete recanalization versus medication therapy (MT) with CTO lesion in DM patients with CTO. This study is a single-center, prospective, all-comer registry designed to reflect "real world" practice since 2004. Of a total of 4909 consecutive patients were diagnosed with significant CAD by coronary angiography (CAG). A total of 372 patients has DM and CTO lesions. Patients were divided into the PCI group (n = 184) and the MT group (n = 179). The primary endpoint, defined as the composite of death or myocardial infarction (MI), was compared between the two groups up to 5 years. In addition, inverse probability weighting (IPTW) analysis, derived from the logistic regression model, was performed to adjust for potential confounders. Compared to the MT group, the PCI group was associated with a significantly reduced incidence of the primary endpoint before [hazard ratio; HR 0.267, 95% confidence interval (CI) 0.116-0.614] and after (HR 0.142, 95% CI 0.032-0.629) adjusting confounding factors by IPTW. Complete revascularization by CTO-PCI with MT in DM patients should be the preferred treatment strategy compared with the MT alone strategy since it reduces the composite of death or MI up to 5 years.

Abstract
Aim Chronic total occlusion of a coronary artery (CTO) is a predictor of early and late cardiovascular mortality and poor cardiovascular outcomes in patients with coronary artery disease. The purpose of this study was to identify predictors of all-cause mortality in CTO patients that underwent invasive treatment.Material and methods Patients between 2012 and 2018 with CTO in at least one vessel, as demonstrated by coronary angiography, were included retrospectively in the study. The patients were divided into two groups, an intervention group (percutaneous and surgical revascularization) and a medical group.Results A total of 543 patients were studied, 152 females (28%) and 391 males (72%). The median follow-up period was 49 (26-72) mos. A total of 186 (34.2%) patients in the medical group and 357 (65.8%) patients in the invasive therapy group were followed. The 5-yr death rate was observed in 50 (26.9%) patients in the medical group and 53 (14.8%) patients in the intervention group, and it was found to be statistically higher in the medical group (p=0.001). In multivariable analysis, heart failure (odds ratio (OR): 1.92, 95% CI: 1.18-3.14; p=0.01), higher glucose levels (OR: 1.05, 95% CI: 1,02-1.08; p=0.04), lower albumin levels (OR: 0.49, 95% Cl: 0.32-0.72; p=0.001), SYNTAX score (OR: 1.03, 95% CI: 1.01-1.05; p=0.001), and CTO (≥2 occluded artery) (OR: 0.42, 95% CI: 0.22-0.72; p=0.01) were independent factors for all-cause mortality.Conclusion In comparison to the revascularized group, there was an increase in mortality among CTO patients treated medically. Heart failure, SYNTAX score, albumin, glucose, and CTO (≥2 occluded arteries) were independent risk factors for all-cause mortality.

Abstract
Background Lesion characteristics were shown to predict procedural success and outcomes in chronic total occlusion (CTO) recanalization. However, diverse techniques involved in these studies might cause potential heterogeneity. Objective The study aimed to test the impacts of lesion characteristics on CTO intervention with a pure antegrade wiring-based technique. Methods and Results We studied consecutive 325 patients (64.5 ± 11.1 years, 285 men) with native CTO lesions intervened by a single operator with an antegrade-based technique between August 2014 and July 2020. Forty-seven patients with antegrade procedural failure (20 with pure antegrade wiring failure and 27 with back-up retrograde techniques) were compared to 278 patients with antegrade-only procedural success. With a median follow-up of 30.8 (16.1–48.6) months, 278 patients with procedural success were further assessed for target vessel failure (TVF: cardiac death, target vessel myocardial infarction [MI], and target lesion revascularization [TLR]). Patients with antegrade procedural success had a lower percentage of history with bypass graft (4 vs. 15%, p = 0.004) and lower Multicenter Chronic Total Occlusion Registry of Japan (J-CTO) score (2.1±1.3 vs. 3.4 ± 1.0, p < 0.001), when compared to those with antegrade failure. The J-CTO score was independently associated with procedural failure (odds ratio = 2.5, 95% CI = 1.8–3.4) in multivariate analysis. However, only clinical features, such as female gender (hazard ratio [HR] = 4.3, 95% CI = 1.4–13.1), estimated glomerular filtration rate <60 ml/min/1.73 m2 (HR = 3.2, 95% CI = 1.0–9.9), and old MI (HR = 4.5, 95% CI = 1.5–12.8), but not J-CTO score, could predict long-term TVF in multivariate Cox regression model. Conclusion The feasibility of the antegrade guidewire-crossing technique for native CTO intervention was highly determined by lesion characteristics. With such a simpler technique, the prognostic impact of lesion complexity shown in studies with multiple recanalization techniques was negligible. This suggested antegrade true lumen tracking techniques deserved to be tried better even for CTO lesions with higher complexity.

Abstract
BACKGROUND Elective percutaneous coronary intervention (PCI) is performed to relieve symptoms of angina. Identifying patients who will benefit symptomatically after PCI would be clinically advantageous but robust predictors of symptom resolution are ill-defined. METHODS Prospective indexing of baseline angina status, clinical, and procedural characteristics were collected over a 5-year period in a regional revascularization registry. At 1-year follow-up, angina resolution was assessed. We performed a stepwise selection algorithm to identify predictors of persistent angina at 1 year. RESULTS A total of 777 patients were included in the analysis and the median follow-up was 387 days. Mean age of the cohort was 66.6 years, 23.8% were female and 23.3% had baseline Canadian Cardiovascular Society class 3 or 4 angina. Overall, 13.1% had persistent angina. The only predictor of persistent angina was the presence of a residual chronic total occlusion after PCI with odds ratio of 3.06 (95% confidence interval, 1.81-5.17). Residual stenoses 50-69%, 70-89%, and 90-99% were not associated with residual angina after PCI. CONCLUSION Most patients achieved symptom resolution with PCI and optimal medical therapy. A residual chronic total occlusion after PCI was associated with persistent angina. Other degrees of stenoses were not associated with persistent angina.

Abstract
OBJECTIVE Endovascular treatment is one of the choices for symptomatic chronic intracranial total occlusion (CITO); however, its safety and efficacy remain unclear. The present study was performed to evaluate the safety and long-term outcome of endovascular treatment for CITO at a high-volume stroke center. METHODS Data about patients with symptomatic CITO who received endovascular treatment were retrospectively collected. Technique success was regarded as ≤ 30% residual stenosis. Periprocedural complications within 30 days were used to evaluate safety. Baseline characteristics and lesion features were compared between patients with successful recanalization and those with recanalization failure. Stroke recurrence and in-stent restenosis (ISR) of the culprit arteries during follow-up were used to evaluate long-term efficacy. RESULTS From June 2012 to September 2019, 117 patients (mean ± SD age 55.8 ± 9.6 years) were included. The successful recanalization rate was 82.9% (97/117 patients). The combined rate of periprocedural stroke, myocardial infarction, and death was 8.5% (10/117). Compared with patients with successful recanalization, patients with recanalization failure had longer occlusion time and longer lesion length (27.0 mm vs 15.4 mm, p = 0.001). In the median 23.0-month clinical follow-up period, recurrent stroke occurred in 12.6% (11/87) of patients with successful recanalization. In the median 5-month imaging follow-up period, ISR was detected in 26.6% (21/79) of patients. CONCLUSIONS Endovascular treatment was relatively safe for patients with symptomatic CITO. Shorter occlusion time and shorter lesion length may be associated with higher recanalization rate. The rates of stroke recurrence and symptomatic ISR were acceptable but need to be confirmed in future studies.

Abstract
BACKGROUND Chronic total occlusions (CTO) are common and are associated with lower percutaneous coronary intervention (PCI) success rates, often due to failure of antegrade guidewire crossing. Local, intralesional delivery of collagenase (MZ-004) may facilitate guidewire crossing in CTO. AIMS To evaluate the effect of MZ-004 in facilitating antegrade wire crossing in CTO angioplasty. METHODS A total of 76 patients undergoing CTO PCI were enrolled at 13 international sites: 38 in the randomized training stage (collagenase [MZ-004] 900 or 1200 μg) and 38 in the placebo-controlled stage (MZ-004 900 or 1200 μg or placebo). Patients received the MZ-004 or identical volume saline (placebo group) in a double-blind design, injected via microcatheter directly into the proximal cap of the CTO. The following day patients underwent CTO PCI using antegrade wire techniques only. RESULTS Patients were generally similar except for a trend for higher Japanese chronic total occlusion (J-CTO) score in the MZ-004 group (MZ-004 J-CTO score 1.9 vs. 1.4, p = 0.07). There was a numerical increase in the rates of guidewire crossing in the MZ-004 groups compared to placebo (74% vs. 63%, p = 0.52). Guidewire crossing with a soft-tip guidewire (≤1.5 g tip load) was significantly higher in the MZ-004 groups (0% in placebo, 17% in 900 μg, and 29% in 1200 μg MZ-004 group, p = 0.03). Rates of the major adverse cardiovascular event were similar between groups. CONCLUSION Local delivery of MZ-004 into coronary CTOs appears safe and may facilitate CTO crossing, particularly with softer tipped guidewires. These data support the development of a pivotal trial to further evaluate this agent.

Abstract
BACKGROUND Chronic total occlusions (CTO) occur in nearly 20% of coronary angiograms. CTO revascularization, either by percutaneous coronary intervention (PCI) or coronary artery bypass grafting surgery (CABG), is infrequently performed, approximately one-third of cases. Long-term outcomes are unknown. The objective of the study was to determine whether early CTO revascularization of patients, either by CABG or PCI, was associated with improved clinical outcomes. METHODS One thousand six hundred twenty-four patients from the Canadian CTO registry were followed for at least 9.75 years. Revascularization was performed according to routine clinical practice. Patients were grouped according to CTO revascularization status (PCI or CABG of CTO vessel, CTO revasc) or no CTO revasc (medical therapy only, or PCI/CABG of non-CTO vessels only), within 3 months of initial angiogram. Patients were followed for mortality, revascularization procedures (PCI and CABG), and hospitalizations for acute coronary syndromes and heart failure. RESULTS Early CTO revasc was performed in 28.2% of patients (17.5% CABG, 10.7% PCI). The CTO revasc group was younger, with more males and generally fewer comorbidities. There was a significantly lower mortality probability at 10 years in the CTO revascularization group (22.7% [95% CI, 19.0%-26.9%]) compared with the no CTO revasc group (36.6% [95% CI, 33.8%-39.5%]). At 10 years, revascularization rates (14.0% versus 22.8%) and acute coronary syndrome hospitalization rates (10.0% versus 16.6%) were significantly lower in the CTO revasc group. Baseline-adjusted analysis showed CTO revasc was associated with significantly lower all-cause mortality (hazard ratio, 0.67 [95% CI, 0.54-0.84]). In both landmark and time varying analyses, association with lower mortality was particularly robust for CTO revascularization by CABG (hazard ratio 0.56 and 0.60, respectively), with a marginally significant result for PCI in the time varying analysis (hazard ratio 0.711 [95% CI, 0.51-0.998]). CONCLUSIONS Early CTO revascularization was associated with significantly lower all-cause mortality, revascularization rates, and hospitalization for acute coronary syndrome at 10 years, and mainly driven by outcomes in patients with CABG.

Abstract
Introduction: P-wave dispersion (PWD) obtained from the standard 12-lead electrocardiography (ECG) is considered to reflect the homogeneity of the atrial electrical activity. The aim of this investigation was to evaluate the effect of percutaneous chronic total occlusion (CTO) revascularization on the parameters of P wave duration and PWD on ECG in cases before and after procedure at 12th months. Methods: We analyzed 90 consecutive CTO cases who were on sinus rhythm and underwent percutaneous coronary intervention (PCI). P-wave maximum (P-max) and P-wave minimum (P-min), P-wave time, and PWD were determined before and twelve months after the CTO intervention. The study population was categorized into two groups as successful and unsuccessful CTO PCI groups. Results: The CTO PCI was successful in 71% of cases (n=64) and it was unsuccessful in 29% of cases (n=26). Both groups, except for age and hypertension, were similar in terms of demographic and clinical aspects. CRP levels were significantly elevated in the unsuccessful CTO PCI group. Pre-PCI ECG parameters showed no significant difference. Irrespective of the target vessel revascularization, we observed that PWD and P-max values were significantly lower in the 12th months follow-up. In all Rentrop classes, PWD values were significantly decreased at 12th months follow-up in comparison to the pre-CTO PCI values. Conclusion: This study has determined that PWD and P-max, which are both risk factors for atrial arrhythmias, are significantly reduced within 12th months after successful CTO PCI regardless of the target vessel.

Abstract
BACKGROUND Description of procedural outcomes using contemporary techniques that apply specialized coronary guidewires, microcatheters, and guide catheter extensions designed for chronic total occlusion (CTO) percutaneous revascularization is limited. METHODS A prospective, multicenter, single-arm study was conducted to evaluate procedural and in-hospital outcomes among 150 patients undergoing attempted CTO revascularization utilizing specialized guidewires, microcatheters and guide extensions. The primary endpoint was defined as successful guidewire recanalization and absence of in-hospital cardiac death, myocardial infarction (MI), or repeat target lesion revascularization (major adverse cardiac events, MACE). RESULTS The prevalence of diabetes was 32.7%; prior MI, 48.0%; and previous bypass surgery, 32.7%. Average (mean ± standard deviation) CTO length was 46.9 ± 20.5 mm, and mean J-CTO score was 1.9 ± 0.9. Combined radial and femoral arterial access was performed in 50.0% of cases. Device utilization included: support microcatheter, 100%; guide catheter extension, 64.0%; and mean number of study guidewires/procedure was 4.8 ± 2.6. Overall, procedural success was achieved in 75.3% of patients. The rate of successful guidewire recanalization was 94.7%, and in-hospital MACE was 19.3%. Achievement of TIMI grade 2 or 3 flow was observed in 93.3% of patients. Crossing strategies included antegrade (54.0%), retrograde (1.3%) and combined antegrade/retrograde techniques (44.7%). Clinically significant perforation resulting in hemodynamic instability and/or requiring intervention occurred in 16 (10.7%) patients. CONCLUSIONS In a multicenter, prospective registration study, favorable procedural success was achieved despite high lesion complexity using antegrade and retrograde guidewire maneuvers and with acceptable safety, yet with comparably higher risk than conventional non-CTO PCI.

Abstract
Aims: We aimed to assess the association between dietary inflammation index (DII) and abdominal aortic calcification (AAC) in US adults aged ≥40 years. Methods: Data were obtained from the 2013-2014 National Health and Nutrition Examination Survey (NHANES). Participants who were <40 years old and missing the data of DII and AAC were excluded. DII was calculated based on a 24-h dietary recall interview for each participant. AAC score was quantified by assessing lateral spine images and severe AAC was defined as AAC score >6. Weighted multivariable regression analysis and subgroup analysis were preformed to estimate the independent relationship between DII with AAC score and severe AAC. Results: A total of 2,897 participants were included with the mean DII of -0.17 ± 2.80 and the mean AAC score of 1.462 ± 3.290. The prevalence of severe AAC was 7.68% overall, and participants in higher DII quartile tended to have higher rates of severe AAC (Quartile 1: 5.03%, Quartile 2: 7.44%, Quartile 3: 8.38%, Quartile 4: 10.46%, p = 0.0016). A positive association between DII and AAC score was observed (β = 0.055, 95% CI: 0.010, 0.101, p = 0.01649), and higher DII was associated with an increased risk of severe AAC (OR = 1.067, 95% CI: 1.004, 1.134, p = 0.03746). Subgroup analysis indicated that this positive association between DII and AAC was similar in population with differences in gender, age, BMI, hypertension status, and diabetes status and could be appropriate for different population settings. Conclusion: Higher pro-inflammatory diet was associated with higher AAC score and increased risk of severe AAC. Anti-inflammatory dietary management maybe beneficial to reduce the risk of AAC.

Abstract
Background/aim Successful coronary chronic total occlusion (CTO) revascularization was found by many studies to be associated with improved left ventricular (LV) systolic function and survival if evidence of viability is present. Little is known about the association of CTO revascularization in patients with electrocardiographic Q waves and improvement in angina burden as a measurement of health-related quality of life (HRQOL) afterwards. Methods In this study, 100 patients with single vessel CTO were included. Myocardial viability was tested by late gadolinium enhancement (LGE) on cardiac magnetic resonance (CMR) and 50 patients showed evidence of viability. Seattle Angina Questionnaire (SAQ) scores were used as a measure of HRQOL. Results Pathological Q waves were present in 48 patients (including 19 patients with viable CTO territory) out of 100 patients. Patients with Q waves tended to have worse Seattle Angina Questionnaire (SAQ) scores compared to those with no Q waves (31.2 ± 11.7 vs 45.3 ± 13.9 respectively, p = 0.002), worse LV systolic function and wall motion score index (WMSI) on CMR. They also had significantly less prevalence of viability (p < 0.001). Patients with Q waves and positive viability had lower SAQ scores (37.2 ± 10.1 vs 52.7 ± 13.2 respectively, p = 0.02), higher LVEF and lower WMSI. They also had well developed collateral grade (2.1 ± 1.03 vs 0.7 ± 0.82 respectively, p < 0.001). After successful percutaneous coronary intervention (PCI), in the viable LV group, presence of Q waves was not associated with better LV functional recovery, while those with higher collateral grades were more likely to have better LV functional recovery post CTO-PCI. Patients with Q waves and viable CTO territory showed significantly better SAQ scores compared to pre-PCI (87.3 ± 12.2 vs 37.2 ± 10.1 respectively, p < 0.001). For angina frequency, post–PCI score was 80.2 ± 7.9 compared to 39.2 ± 7.1 before PCI, p < 0.001). Multivariate regression analysis showed that pathological Q waves, Rentrop's collateral grade and the Canadian Cardiovascular Society (CCS) angina class before PCI were the most significant independent predictors of improved HRQOL as reflected by SAQ (OR for Q waves 7.83, 95% CI 1.62–18.91,p 0.003), (OR for Rentrop's collateral grade 8.31,95% CI 2.21–26.33, p < 0.001), (OR for CCS class 8.39, 95% CI 1.21–20.8, p 0.01). Conclusion Well-developed collateral circulation could independently predict LV functional recovery after CTO-PCI. Patients with Q waves and viable CTO territory tend to have higher CCS class before revascularization and get significant improvement of HRQOL after PCI. Other predictors of improved HRQOL are Rentrop's collateral grade and worse CCS class before PCI.

Abstract
The aim of this study was to investigate the impact of chronic total occlusion (CTO) on clinical outcomes in patients with calcified coronary lesions receiving rotational atherectomy (RA). This multi-center registry enrolled consecutive patients with calcified coronary artery disease who underwent RA during percutaneous coronary intervention (PCI) from 9 tertiary centers in Korea between January 2010 and October 2019. The primary outcome was target-vessel failure (TVF) which included the composite of cardiac death, target-vessel myocardial infarction (TVMI), and target-vessel revascularization (TVR). A total of 583 lesions were enrolled in this registry and classified as CTO (n = 42 lesions, 7.2%) and non-CTO (n = 541 lesions, 92.8%). The CTO group consisted of younger patients who were more likely to have a history of previous percutaneous coronary intervention or coronary artery bypass graft surgery. The incidence of the primary outcome was 14.1% and 16.7% for the non-CTO group and CTO group, respectively. The primary outcomes observed in the two groups were not significantly different (log-rank p = 0.736). The 18-month clinical outcomes of the CTO group were comparable to those of the non-CTO group in multivariate analysis. About 7% of patients requiring RA have CTO lesions and these patients experience similar clinical outcomes compared with those having non-CTO lesions. Use of RA for CTO lesions was safe despite higher procedural complexity.

Abstract
BACKGROUND No previous reports have described the comprehensive care pathways involved in chronic total occlusion percutaneous coronary intervention (CTO PCI). METHODS In a study of 1,000 consecutive patients undergoing CTO PCI using hybrid approach, a systematic algorithm of selecting CTO PCI strategies, the procedural characteristics, complication rates, and patient reported health status outcomes through 12 months were assessed. RESULTS Technical success of the index CTO PCI was 86%, with 89% of patients having at least one successful CTO PCI within 12 months. A total of 13.8% underwent CTO PCI of another vessel or reattempt of index CTO PCI within 1 year. At 1 year, the unadjusted major adverse cardiac and cerebral event (MACCE) rate was lower in patients with successful index CTO PCI compared to patients with unsuccessful index CTO PCI (9.4% vs. 14.6%, p = .04). The adjusted hazard ratios of myocardial infarction and death at 12 months were numerically lower in patients with successful index CTO PCI, compared to patients with unsuccessful index CTO PCI. Patients with successful index CTO PCI reported significantly greater improvement in health status throughout 12-months compared to patients with unsuccessful index CTO PCI. CONCLUSION CTO-PCI in the real-world often require treatment of second CTO, non-CTO PCI or repeat procedures to treat initially unsuccessful lesions. Successful CTO PCI is associated with numerically lower MACCE at 1 year and persistent symptomatic improvement compared to unsuccessful CTO PCI. Understanding the relationship between the care pathways following CTO PCI and health status benefit requires further study.

Abstract
INTRODUCTION Current guidelines for chronic total occlusion (CTO) percutaneous coronary intervention (PCI) recommend dual coronary angiography. AIM OF THE STUDY Evaluate CTO-PCI with a single approach using safety indices through the microcatheter. POPULATION AND METHODS Prospective observational study with a consecutive inclusion of 39 patients (mean age of 67 years) treated by antegrade approach without scheduled contralateral angiography. Following safety indices were collected: blood backflow, distal coronary pressure waveform, selective distal contrast injection. RESULTS Technical success was obtained in 90% of the cases. Balloon dilation was used in 38% of the cases before placement of the microcatheter. Dual angiography was necessary in three cases (8%). A blood backflow and cyclic changes of the distal coronary pressure waveform were noticed in 87% and 84% of the cases, with a positive predictive value of 97% and 79% respectively, for a microcatheter location in the true lumen. Selective distal contrast injection was done in 36 cases with a visualization of the true lumen in 35 cases. One major complication was observed (3%). CONCLUSION CTO-PCI with a single approach is feasible using safety indices to limit the risks of major complication. The principle of a systematic dual angiography as advocated in current guidelines may deserve to be revisited.

Abstract
Revascularization of chronic total occlusion (CTO) is still debated regarding its indications and therapeutic benefits. Guidelines recommend patient selection based on ischemia detection and viability assessment. We aimed to investigate the relationship between the quality of coronary collaterals (CC), graded by Rentrop classification, and myocardial viability assessed by cardiovascular magnetic resonance (CMR). Unselected 100 consecutive patients with a single CTO were prospectively enrolled. CC of Rentrop grade two or three were considered as well-developed. Analyzing late gadolinium enhancement (LGE) images, CTO territories with mean segmental transmural scar extent < 50% were considered viable. Of the 100 patients (70 male, mean age 58.0 ± 6 years), 73 patients (73%) had angiographically visible CC. Based on LGE, patients were classified into viable (n = 50) and non-viable (n = 50) groups. Significant differences between both groups existed regarding frequency of diabetes mellitus (p = 0.044), frequency of congestive heart failure (p = 0.032), presence of pathological Q in CTO territory (p = 0.039); and presence of well-developed CC (p < 0.001). Binary logistic regression and receiver operating characteristic curve showed that presence of well-developed CC could independently (OR 9.4, 95% CI: 2.6-33.6, p < 0.001) predict myocardial viability with a sensitivity and a specificity of 72% and 74%, respectively (AUC: 0.796, 95% CI: 0.708-0.884, P < 0.001). The presence of well-developed CC could independently predict with high accuracy myocardial viability assessed by LGE in territories subtended by CTO vessels. Therefore, search for viable myocardium using different imaging modalities, e.g. CMR, may be recommended in CTO patients with well-developed CC.

Abstract
Although remarkable progress in percutaneous coronary intervention (PCI) has been achieved over the last decade, the success rate of chronic total occlusion (CTO) recanalization varies greatly. Coronary angiography characteristics may affect the success rate of CTO recanalization. This study sought to establish a scoring model to predict successful CTO recanalization based on coronary angiography characteristics. We analyze 287 angiography data from patients who underwent elective PCI. Angiography characteristics being measured were lesion location, blunt stump, calcification, ostial lesion, bridging collateral, bending, side branch, tortuosity, previous stent attempt, and lesion length of >20 mm. Data were analyzed using SPSS 25.0. Multivariate analysis shows that side branch lesion ( p = 0.000), proximal vessels tortuosity ( p = 0.015), calcified lesion ( p = 0.000), lesion length of >20 mm ( p = 0.000), and blunt stump ( p = 0.000) can predict the successful PCI in the CTO. ROC curve analysis of the score ability to predict successful PCI in the CTO showed area under curve of 0.89 (confidence interval 95%), the cutoff point of ≤2 with a sensitivity of 93.33%, and specificity of 88.23%. We concluded that the five angiography characteristics that strongly associate with successful PCI in the CTO are calcified lesion, blunt stump, lesion length >20 mm, proximal vessel tortuosity, and side branch lesion. This score may help cardiologists to predict the success probability of PCI in the CTO.

Abstract
BACKGROUND The QRS-T angle (QRS-Ta) is a novel marker of myocardial repolarization heterogeneity which is related to adverse cardiovascular events. Our aim in this study was to investigate the effect of successful percutaneous coronary intervention (PCI) on frontal QRS-Ta in patients with chronic total occlusion (CTO). MATERIALS AND METHODS A total of 132 patients undergoing PCI for CTO were included in this study. Successful PCI of CTO segment was performed in 84 patients (group 2) while 48 who failed CTO were observed (group 1). Baseline demographic and clinical variables were evaluated and, 12-lead surface ECGs of all subjects were recorded before performing coronary angiography and 1-month and 6-month after the index procedure. RESULTS QRS-Ta values significantly decreased during follow-up visits compared to baseline values [92.5 (63.25-110.75); 85.0 (59.0-101.0); 80.0 (53.0-99.0), P < 0.001] in group 2 patients. Moreover, there was no significant difference in frontal QRS-Ta measurements in group 1 patients in their clinical 6-month follow-up [87.0 (48.25-103.0); 86.5 (46.0-101.75); 84.0 (49.0-103.75); P = 0.320]. First month frontal QRS-Ta values [92.5 (63.25-110.75); 85.0 (59.0-101.0), P = 0.002] and sixth month frontal QRS-Ta values [92.5 (63.25-110.75); 80.0 (53.0-99.0), P < 0.001] were lower than baseline values while sixth month values [85.0 (59.0-101.0); 80.0 (53.0-99.0), P = 0.002] was lower compared to first month values. Additionally, a decrease in frontal QRS-Ta was observed regardless of target vessel or Rentrop classification. CONCLUSION Successful percutaneous revascularization of CTO was effective in ventricular repolarization. Frontal QRS-Ta significantly decreased after successful PCI on CTO patients at a 6-month follow-up.

Abstract
Background: To date, the benefit of successful revascularization of chronic total occlusions (CTOs) on prognosis remains uncertain, and there is a paucity of data on the impact of successful revascularization for CTO patients on long-term cardiovascular survival. This study aimed to investigate the long-term cardiovascular survival for patients with successful and unsuccessful CTO revascularization in a large cohort of patients. Methods: There were 1,655 consecutive patients with at least one CTO included and were grouped into successful revascularization (n = 591) and unsuccessful revascularization (n = 1,064). Propensity score matching (PSM) was carried out to balance the clinical and the angiographic characteristics. Cardiac mortality was defined as the primary endpoint. Major adverse cardiac event (MACE) was assessed as a “secondary endpoint.” Results: After 3.6 years of follow-up, there was no significant difference between the successful and the unsuccessful revascularization groups in the rate of cardiac mortality [adjusted hazard ratio (HR) 0.96, 95% confidence interval (CI) 0.59–1.58, p = 0.865]. After the PSM analysis (371 pairs) between the two groups, the cardiac mortality rate values (HR 0.51, 95% CI 0.23–1.15, p = 0.104) were equivalent, whereas the adjusted risk of MACE (HR 0.43, 95% CI 0.32–0.58, p = 0.001) and target-vessel revascularization (HR 0.41, 95% CI 0.29–0.58, p < 0.001) were significantly higher in patients with unsuccessful revascularization. Conclusion: For the treatment of CTO patients, successful revascularization was not associated with a lesser risk for cardiac mortality as compared with unsuccessful revascularization. However, successful revascularization reduced MACE and target-vessel revascularization.

Abstract
BACKGROUND The procedural safety of dissection and reentry (DR) techniques in chronic total occlusion (CTO) percutaneous coronary intervention (PCI) remains controversial, when compared with conventional wire escalation (WE) techniques. The meta-analysis was performed to evaluate the impact of DR techniques vs. WE techniques on periprocedural outcomes in patients with CTO undergoing PCI. METHODS Studies were searched in electronic database from inception to December 2018. Results were pooled using random effects model and fixed effects model. RESULTS The pooled analyses revealed that DR techniques increased risks of periprocedural complications in patients with CTO PCI, including higher coronary perforation rate [risk ratio (RR) = 2.10, 95% confidence interval (CI) 1.24-3.55], periprocedural myocardial infarction (RR = 1.85, 95% CI 1.23-2.78), branch occlusion (RR = 2.69; 95% CI 1.92-3.77) and coronary hematoma (RR = 3.06; 95% CI 2.45-3.82) detected by intravascular ultrasound, when compared to those with WE techniques. However, DR techniques were more applied in patients with higher complexity CTO lesions, which was evidenced by higher J-CTO score [standard mean differences (SMD) = 0.71, 95% CI 0.51-0.91] and longer fluoroscopy time (SMD = 0.93, 95% CI 0.70-1.16), that may explain the higher complications rates in the DR techniques group as compared with WE techniques. CONCLUSION The present meta-analysis suggests that the DR technique is relatively frequently used during contemporary CTO PCI, especially for challenging more complex CTO lesions. However, it is associated with higher, yet acceptable, rates of periprocedural adverse events as compared with a conventional WE strategy. Further refinement of DR techniques and evidence from large RCTs is needed to define the optimal role of DR in hybrid CTO PCI.

Abstract
The proportion of the elderly in the total population of the world is growing, and the number of elderly patients with coronary chronic total occlusions (CTO) is huge. The elderly patients often have more extensive coronary artery disease, more severe ischemic burden and higher risk of cardiovascular events, as compared to younger patients, and thereby they might greatly benefit from coronary revascularization, even though they may have higher risk of operative complications. Most interventional cardiologists are more likely to be reluctant to operate complex percutaneous coronary intervention (PCI) in elderly patients. The latest refinements in dedicated CTO-PCI equipment and techniques have led to high rates of success and low complications rates and have made the CTO-PCI procedures safe and effective among the elderly patients. However, up to now, there is no widely recognized consensus or guideline on treatment strategy of elderly CTO patients, and the prognosis in this population is unknown. In this review, we aim to provide an overview of the current evidence and future perspectives on PCI in elderly patients with CTOs.

Abstract
BACKGROUND Chronic total occlusion (CTO) of a coronary artery is defined as an occluded segment with no antegrade flow and a known or estimated duration of at least 12 weeks. OBJECTIVE We considered the current literature describing the indications and clinical outcomes for denovo CTO- percutaneous coronary intervention (PCI), and discuss the role of CTO-PCI and future directions for this procedure. METHODS Databases (PubMed, the Cochrane Library, Embase, EBSCO, Web of Science, and CINAHL were searched and relevant studies of CTO-PCI were selected for review. RESULTS The prevalence of coronary artery CTO's has been reported to be ~ 20% among patients undergoing diagnostic coronary angiography for suspected coronary artery disease. Revascularization of any CTO can be technically challenging and a time-consuming procedure with relatively low success rates and may be associated with a higher incidence of complications, particularly at non-specialized centers. However, with an increase in experience and technological advances, several centers are now reporting success rates above 80% for these lesions. There is marked variability among studies in reporting outcomes for CTO-PCI with some reporting potential mortality benefit, better quality of life and improved cardiac function parameters. Anecdotally, properly selected patients who undergo a successful CTO-PCI most often have profound relief of ischemic symptoms. Intuitively, it makes sense to revascularize an occluded coronary artery with the goal of improving cardiovascular function and patient quality of life. CONCLUSION CTO-PCI is a rapidly expanding specialized procedure in interventional cardiology and is reasonable or indicated if the occluded vessel is responsible for symptoms or in selected patients with silent ischemia in whom there is a large amount of myocardium at risk and PCI is likely to be successful.

Abstract
Background: Percutaneous coronary intervention (PCI) is widely used in patients with chronic total occlusion (CTO), but its benefit in improving long-term outcomes is controversial. We aimed to develop a prediction score for grading “survival advantage” conferred by successful results of CTO-PCI and a scoring system for prediction of the influence of CTO-PCI results on major adverse cardiac and cerebrovascular events (MACCEs). Methods: Follow-up data of 2625 patients who underwent CTO-PCI at 65 Japanese centers were analyzed. An integer scoring system was developed by including statistical effect modifiers on the association between successful CTO-PCI and one-year mortality. Results: Follow-up at 12 months was completed in 2034 patients. During follow-up, 76 deaths (3.7%) occurred. Patients with successful CTO-PCI had a better one-year survival than patients with failed CTO-PCI (log rank P = 0.016). Effect modifiers for the association between successful procedure and one-year mortality included diabetes (P interaction = 0.043), multivessel disease (P interaction = 0.175), Canadian Cardiovascular Society class ≥2 (P interaction = 0.088), and prior myocardial infarction (MI) (P interaction = 0.117). Each component was assigned a single point and summed to develop the scoring system. The patients were then categorized to specify the prediction of survival advantage by successful PCI: ≤2 (normal) and ≥3 (distinct). The differences in one-year mortality between patients with successful and failed treatment were −0.7% and 11.3% for normal and distinct score categories, respectively. In the scoring system for MACCE, score components were prior MI (P interaction = 0.19), left anterior descending artery (LAD)-CTO (P interaction = 0.079), and reattempt of CTO-PCI (P interaction = 0.18). The differences in one-year MACCEs between successful and failed patients for each score category (0, 1, and ≥2) were −1.7%, 7.5%, and 15.1%, respectively. Conclusions: The novel scoring system assessing the advantage of successful PCI can be easily applied in patients with CTO. It is a valid instrument for clinical decision-making while assessing the survival advantage of CTO-PCI and the influence of procedural results on MACCEs.

Abstract
The retrograde approach has increased the success rate of chronic total occlusion percutaneous coronary intervention but has also been associated with a higher risk of complications. The retrograde approach is usually performed in complex lesions, in which the antegrade approach is not feasible or has failed previously. Using a systematic 10-step approach can maximize the likelihood of success and minimize the risks of retrograde chronic total occlusion interventions.

Abstract
Background Recently, the importance of chronic total occlusion (CTO)-percutaneous coronary intervention (PCI) has been emphasized with greater success rates. In the antegrade wire based approach, it is generally considered that the guidewire would not advance from the subintimal space to the intimal space without dissection re-entry device. However, it is sometimes observed by intravascular ultrasound (IVUS) that the guidewire within the subintimal space advanced into the distal true lumen. The purpose of this study was to investigate specific conditions or characteristics which were associated with “antegrade true-sub-true” phenomenon in CTO-PCI. Methods We retrospectively reviewed consecutive 320 CTO lesions that underwent CTO-PCI in our institution. Among them, 16 lesions in which the IVUS confirmed the “antegrade true-sub-true” phenomenon were categorized as the true-sub-true group, whereas 27 lesions that resulted in unsuccessful CTO-PCI were categorized as the unsuccessful group. We compared the clinical, lesion, and procedural characteristics between the true-sub-true group and the unsuccessful group. Results The prevalence of bifurcation with abrupt type in CTO exit-sites was significantly higher in the true-sub-true group in comparison to the unsuccessful group (75.0% vs. 25.9%, p = 0.002). The multivariate logistic regression analysis revealed that bifurcation with abrupt type in CTO exit-site (OR 8.017; 95%CI: 1.484–43.304; p = 0.016) was independent predictor of the antegrade true-sub-true phenomenon. Conclusions In CTO-PCI, the antegrade true-sub-true phenomenon is rare, but can be a last chance for successful PCI. Bifurcation with abrupt type in CTO exit-site was significantly associated with the antegrade true-sub-true phenomenon.

Abstract
AIMS Chronic total occlusion (CTO) has been linked to worse survival. While controversial and limited to observational data, successful CTO percutaneous coronary intervention (PCI) has been associated with improved left ventricular (LV) function and mortality. However, the role of CTO PCI prior to transcatheter aortic valve replacement (TAVR) is not clear. We sought to explore the prognostic impact of a pre-TAVR CTO on post-TAVR outcomes. METHODS AND RESULTS We retrospectively reviewed 783 consecutive TAVR cases performed at a single tertiary care medical center. Pre-TAVR angiograms were analyzed for the presence of a CTO. At the time of TAVR, 12.6% (n = 99) patients had a CTO. At one-year post-TAVR, there was no significant association between the presence of a CTO and death (14.2% vs 13.1%, p = 0.75), functional status, quality of life, or adverse events. There was also no difference in long-term survival (4.1 years vs 4.1 years, p = 0.55). LV ejection fraction was lower in the CTO group at baseline and one year (p < 0.01). CONCLUSIONS The presence of a CTO did not have any prognostic impact on mortality, change in LV function, or improvement in functional status and angina scores following TAVR in our cohort of elderly, high-risk patients. CTO before TAVR was associated with decreased ejection fraction at baseline and at one year.

Abstract
BACKGROUND The American College of Cardiology/American Heart Association Appropriate Use Criteria were designed to aid clinical decision-making, yet their association with health status outcomes after chronic total occlusion percutaneous coronary intervention (PCI) is unknown. METHODS We analyzed 769 patients with baseline and 1-year health status data after chronic total occlusion PCI. Procedures were categorized as appropriate, may be appropriate, or rarely appropriate. Mean changes in patient-reported health status, assessed by the Seattle Angina Questionnaire (SAQ), were compared across appropriate use criteria categories from baseline to 1 year. Change in SAQ summary score was stratified as little to no benefit (≤10 points), intermediate (10-19 points), large (20-29 points), and very large (≥30 points). RESULTS The appropriate use criteria indication was appropriate in 573 patients (74.5%), may be appropriate in 191 (24.8%), and rarely appropriate in 5 (0.7%). Patients in the appropriate group reported greater improvement in SAQ summary scores (27.3±21.3 points) at 1 year compared with the may be appropriate (22.5±20.9; P=0.01). A similar pattern was noted for SAQ angina frequency (mean change 24.0±27.2 versus 18.7±25.6; P=0.02). The appropriate group had the highest proportion of very large improvements in SAQ summary scores (44.5% versus 33.3%; P=0.01). CONCLUSIONS Among patients undergoing chronic total occlusion PCI, the rate of rarely appropriate PCI was low. The rate of appropriate PCI was high and was associated with the greatest health status improvement at 1 year. A substantial proportion of patients in the may be appropriate group experienced meaningful health status benefits as well.

Abstract
OBJECTIVES This study sought to describe the association between chronic total occlusion (CTO) revascularization (CTO percutaneous coronary intervention [PCI]) and health status in patients with and without cardiomyopathy. BACKGROUND Prior PCI trials for cardiomyopathy have excluded CTO patients. Whether patients with reduced left ventricular ejection fraction (LVEF) receive similar health status benefit from CTO-PCI compared with patients with normal LVEF is unclear. METHODS We assessed health status change, using the Seattle Angina Questionnaire (SAQ) Summary, SAQ Angina Frequency, and Rose Dyspnea Scale scores, among patients undergoing successful CTO PCI in the OPEN-CTO (Outcomes, Patient Health Status, and Efficiency in Chronic Total Occlusion) Registry. Participants were classified by LVEF (normal, ≥50%; mild-moderate, 30% to 49%; and severe, <30%), with higher SAQ and lower Rose Dyspnea Scale scores indicating better health status. Differences in 1-year outcomes were compared using hierarchical multivariable regression. RESULTS Of 762 patients, 506 (66.4%), 193 (25.3%), and 63 (8.3%) had normal, mild-moderate, and severely reduced LVEF. SAQ Summary score improvements were observed in each group (27.1 ± 20.4, 26.7 ± 21.2, and 20.3 ± 18.1, respectively). Compared with patients with LVEF ≥50%, those with LVEF <30% had less improvement in SAQ Summary Score (-5.2 points; 95% confidence interval: -9.0 to -1.5; p = 0.01) and Rose Dyspnea Scale (+0.5 points; 95% confidence interval: 0.1 to 0.8; p = 0.01), with no difference in odds of angina (odds ratio: 1.3; 95% confidence interval: 0.6 to 3.0; p = 0.48). Health status improvement was similar between patients with LVEF ≥50% and LVEF 30% to 49%. CONCLUSIONS Although health status improvement was less in patients with severely reduced LVEF compared with those with normal LVEF, each group experienced large health status improvements after CTO-PCI.

Abstract
BACKGROUND Successful revascularization of chronic total occlusions has been associated with potential effects on left ventricular (LV) function. Strain and strain rate are more sensitive measures of LV mechanics than LV ejection fraction (LVEF). This study was conducted to investigate the impact of revascularization of chronic total occlusion (CTO) on LV function using tissue Doppler (TDI) strain echocardiography. RESULTS This study included 60 patients divided into two main groups: the percutaneous coronary intervention (PCI) group including patients who had a successful PCI of CTO on left anterior descending (LAD) artery and was presented for elective PCI with symptomatic angina and/or positive functional ischemic study. They included 18 males with a mean age of 57 ± 5 years. The optimum medical treatment (OMT) group, including 30 patients, had non-revascularized CTO-LAD and was kept on OMT alone; 20 of them were males with a mean age of 58 ± 4 years. In the PCI group, there was a significant improvement in all the TDI strain parameters of the LAD territory segments. Six months after PCI, the peak systolic strain rate improved from - 0.65 ± 0.21 to 1.05 ± 0.31 1/s (p value < 0.01), the peak systolic strain improved from 6.54 ± 2.48 to 11.51 ± 3.33% ( p value < 0.001 ), and the end systolic strain improved from 7.88 ± 2.77 to 10.51 ± 3.14% (p value < 0.01 ). There was no significant improvement in the mean LVEF (60.70 ± 8.33 vs 61.91 ± 8.16% (p value = 0.6)). In the OMT group, there was no improvement in all the strain parameters and there was no change in the mean LVEF. In the PCI group, there was a significant improvement in the angina class (p value = 0.03) while, in the OMT group, there was no significant improvement (p value = 0.835). CONCLUSIONS Successful PCI for CTO improved regional LV myocardial function assessed by TDI strain echocardiography. This improvement was associated with improvement in the angina class.

Abstract
BACKGROUND Successful chronic total occlusion (CTO) percutaneous coronary intervention (PCI) can markedly reduce angina symptom burden, but many patients often remain on multiple antianginal medications (AAMs) after the procedure. It is unclear when, or if, AAMs can be de-escalated to prevent adverse effects or limit polypharmacy. We examined the association of de-escalation of AAMs after CTO PCI with long-term health status. METHODS In a 12-center registry of consecutive CTO PCI patients, health status was assessed at 6 months after successful CTO PCI with the Seattle Angina Questionnaire and the Rose Dyspnea Scale. Among patients with technical CTO PCI success, we examined the association of AAM de-escalation with 6-month health status using multivariable models adjusting for revascularization completeness and predicted risk of post-PCI angina (using a validated risk model). We also examined predictors and variability of AAMs de-escalation. RESULTS Of 669 patients with technical success of CTO PCI, AAMs were de-escalated in 276 (35.9%) patients at 1 month. Patients with AAM de-escalation reported similar angina and dyspnea rates at 6 months compared with those whose AAMs were reduced (any angina: 22.5% vs 20%, P = .43; any dyspnea: 51.8% vs 50.1%, P = .40). In a multivariable model adjusting for complete revascularization and predicted risk of post-PCI angina, de-escalation of AAMs at 1 month was not associated with an increased risk of angina, dyspnea, or worse health status at 6 months. CONCLUSIONS Among patients with successful CTO PCI, de-escalation of AAMs occurred in about one-third of patients at 1 month and was not associated with worse long-term health status.

Abstract
BACKGROUND Chronic total occlusion (CTO) continues to be challenging lesion subset for percutaneous intervention. Last decade has seen tremendous increase in percutaneous coronary intervention (PCI) in this subset owing to improved understanding of the anatomy and enhanced skillset with availability of dedicated hardware. We sought to study the outcomes of CTO PCI in an Indian public hospital. METHODS This was a single-center non-randomized descriptive follow-up study on CTO PCI. The end-points were procedural success, immediate, and late adverse cardiovascular events [major adverse cardiac event (MACE)] and change in angina and left ventricular function at follow-up. RESULTS A total 389 CTO lesions were treated with a success rate of 87% (339/389). The mean Japanese chronic total occlusion (J-CTO) score was 1.78 ± 0.12 (mean ± standard deviation). Multivariate analysis of different angiographic components of J-CTO score identified tortuosity (p = 0.001), calcifications (p ≤ 0.001), and blunt stump (p = 0.007) as independent predictors of procedural failure. The periprocedural mortality was less than 1%, and the non-life threatening complications were about 4%. The MACE rate was significantly higher in the procedural failure group (60%) than in the procedural success group (5.3%, p < 0.001). An increase in left ventricular ejection fraction (LVEF) was noted following successful CTO PCI after complete revascularization. CONCLUSIONS The success rates for CTO PCI in this registry were about 87%. Immediate and long-term clinical outcomes were better with lower MACE (5%) after a successful procedure. A key outcome variable included an increase in LVEF among patients after a successful CTO PCI. The overall periprocedural complications were about 5.5%, but majority were non-life threatening.

Abstract
BACKGROUND Limited study has detailed the procedural outcomes and utilization of contemporary coronary guidewires and microcatheters designed for chronic total occlusion (CTO) percutaneous revascularization and with application of modern techniques. PATIENTS AND METHODS A prospective, multicenter, single-arm trial was conducted to evaluate procedural and in-hospital outcomes among 163 patients undergoing attempted CTO revascularization with specialized guidewires and microcatheters. The primary endpoint was defined as successful guidewire recanalization and absence of in-hospital cardiac death, myocardial infarction, or repeat target vessel revascularization (major adverse cardiac events). RESULTS The prevalence of diabetes was 42.9%; prior myocardial infarction, 41.1%; and previous bypass surgery, 36.8%. Average (mean±SD) CTO length was 41±29 mm, and mean Japanese CTO score was 2.6±1.3. A guidewire support catheter was used in 91.7% of cases, and the mean number of CTO-specific guidewires per procedure was 3.1±2.9. Overall, procedural success was observed in 73.0% of patients. The rate of successful guidewire recanalization was 89.0%, and absence of in-hospital major adverse cardiac event was 81.0%. Methods included antegrade (45.4%), retrograde (5.5%) and combined antegrade/retrograde techniques (49.1%). Total mean procedure time was 119±68 min; mean radiation dose, 2613±1881 mGy; and contrast utilization, 287±142 ml. Clinically significant perforation resulting in hemodynamic instability and/or requiring intervention occurred in 13 (8.0%) patients. CONCLUSION In this multicenter, prospective registration trial representing contemporary technique, favorable procedural success and early clinical outcomes inform technique and strategy using dedicated CTO guidewires and microcatheters in a high lesion complexity patient population.

Abstract
The impact of chronic kidney disease (CKD) and potential pharmacologic intervention on clinical outcomes after percutaneous coronary intervention (PCI) for chronic total occlusions (CTOs) remains unknown. A total of 1,463 patients underwent successful CTO-PCI between August 2004 and December 2014. Major adverse cardiovascular events (MACE) defined as the composite of all-cause death, myocardial infarction and target lesion revascularization, cardiac death, and stent thrombosis were compared between patients with and without CKD (555 and 908 patients, respectively). The results demonstrated higher risks of MACE (log-rank p = 0.015), all-cause death (log-rank p <0.001), and cardiac death (log-rank p <0.001) in the CKD group compared with the non-CKD group. Multivariable analyses demonstrated that CKD was an independent predictor for MACE (hazard ratio 1.23, 95% confidence interval 1.02 to 1.47, p = 0.03). With regard to pharmacotherapy, statin use was associated with significantly lower rates of MACE in the CKD group (log-rank p = 0.003). In conclusion, the presence of CKD would be an important predictor of long-term clinical outcomes in patients who underwent CTO-PCI, and use of statin may influence in reducing the adverse clinical outcomes.

Abstract
Background It was under debate whether chronic total occlusion (CTO) patients could benefit from percutaneous coronary intervention (PCI). We sought to compare clinical outcomes of PCI and optimal medical therapy (OMT) in these patients. Methods PubMed, Embase and Cochrane Library were searched for studies enrolling patients with CTO who accepted PCI or OMT. The meta-analysis was performed by using a random-effect model. In addition, subgroup analyses were performed, including patients after propensity-matching and patients with CTO in infarct-related artery (IRA), respectively. Results We identified 5 studies enrolling 4,761 participants in this meta-analysis. In the main analysis, when compared with OMT, PCI was associated with significant improvement in all-cause death [risk ratio (RR) 0.41, 95% CI: 0.35-0.48], cardiac death (RR 0.44, 95% CI: 0.35-0.55) and major adverse cardiac events (MACE) (RR 0.64, 95% CI: 0.43-0.97). But there were no differences in myocardial infarction (MI) and stroke. The results of the propensity-matched subgroup were somewhat consistent with those of the main analysis (all-cause death: RR 0.57, 95% CI: 0.26-0.89; MI: RR 0.54, 95% CI: 0.32-0.77; and MACE: RR 0.76, 95% CI: 0.33-1.18). In IRA subgroup, PCI reduced risks of mortality (all-cause death: RR 0.41, 95% CI: 0.34-0.49; cardiac death: RR 0.44, 95% CI: 0.35-0.56) and MACE (RR 0.71, 95% CI: 0.46-1.10). But no difference was observed in MI. Conclusions PCI was associated with improved survival and reduced MACE relative to OMT.

Abstract
We performed a retrospective analysis of 146 chronic total occlusion CTO patients to evaluate the antecedents of success and failure in CTO – Percutaneous Coronary Intervention (PCI) in Indian patients. The study aimed to identify the technical success rate, analyse immediate patient outcomes, and understand the factors impacting the successful outcomes. Our results showed that J-CTO (Multicenter CTO Registry of Japan) scores correlate well with the success rates of CTO-PCI and two most important factors deciding failure are lesion length more than 20 mm and lesions with calcification. Most important step to success of CTO is wiring, once wire crosses the segment, success rates of the procedure is around 97%. The wire escalation strategy has to be modified once the initial soft (polymer) wire fails, it’s reasonable to use high tip load wire like conquest pro without the use of intermediate wires (except in presence of tortuosity). At 1 year follow up of these patients, there was a statistically significant drop in angina class and major adverse cardiac event rates in the successful CTO group.

Abstract
Objective To investigate the morphological changes of coronary chronic total occlusion (CTO) as determined by coronary computed tomography angiography (CCTA) follow-up using semi-automated quantitative analysis. Materials and Methods Thirty patients with 31 CTO lesions confirmed by invasive coronary angiography and baseline/follow-up CCTA were retrospectively included. CTOs were quantitatively analyzed by a semi-automated coronary plaque analysis software (Coronary Plaque Analysis, version 2.0, Siemens) after manually determining the lesion border. Recanalized lumen was defined as the linear-like enhanced opacity traversing the non-opacified occluded segment. Other parameters, such as total occlusion length, total occlusion volume, volume with low attenuation component (< 30 Hounsfield unit [HU]), volume with middle to high attenuation component (30–190 HU) as well as the calcification volume, were also recorded. Results Recanalized lumen was found within 48.4% (15/31) occlusions on the follow-up CCTA, compared to 45.2% (14/31) occlusions on the baseline CCTA. Eleven of 14 lesions (78.6%) with CT-visible recanalized lumen within CTOs had a shorter occlusion length on follow-up compared to only 3 of 17 lesions (17.6%) without CT-visible recanalized lumen (odds ratio, 17.1, p < 0.001). The percentage of low attenuation component of occlusions was smaller on follow-up CCTA compared to baseline value (18.1 ± 20.1% vs. 22.6 ± 19.6%, p = 0.033). Conclusion Coronary computed tomography angiography enables non-invasive characterization of natural progression of untreated CTO lesions. Recanalized lumen within CTOs observed at baseline CCTA was associated with shortening of occlusion length on follow-up. Compared to their earlier stage, occlusions of later stage were presented with higher density of non-calcified components.

Abstract
Background This study evaluated the feasibility of using two-dimensional speckle tracking echocardiography (2D-STE) to monitor left ventricular (LV) and overall function after percutaneous recanalization. Methods LV function after percutaneous recanalization was monitored by 2D-STE and conventional echocardiography in 43 patients with coronary chronic total occlusion (CTO) who underwent primary percutaneous coronary intervention (PCI). Follow-ups were carried out 1 day as well as 3 and 6 months after CTO-PCI. At each time point, LV ejection fraction (LVEF) was examined by echocardiography, and LV global longitudinal strain (GLS) was measured by 2D-STE. Results It was found that the global longitudinal strain assessed with 2D-STE was improved as early as 1 day after CTO-PCI, whereas LVEF tended to improve up to 3 and 6 months after CTO-PCI. Conclusion PCI can effectively improve LV function in patients with CTO. 2D-STE is a superior technique for objectively quantifying the functional change earlier.

Abstract
Patient selection for and predicting clinical outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) remain challenging. We hypothesized that both J-CTO (Multicenter Chronic Total Occlusion Registry of Japan) and PROGRESS CTO (Prospective Global Registry for the Study of Chronic Total Occlusion Intervention) scores will predict not only angiographic success but also long-term clinical outcomes of the patients who underwent PCI of CTO. Of 325 CTO PCIs performed at 2 Emory University hospitals from January 2012 to August 2015, 249 patients with complete baseline clinical, angiographic and follow-up data, were included in this analysis. Major adverse cardiovascular events (MACEs) consisted of a composite of death, myocardial infarction, and target vessel revascularization. Mean age was 63 ± 11 years old and mean follow-up was 19.8 ± 13.1 months. Angiographic success rates increased from 74.5% in 2012 to 85.7% in 2015. Greater J-CTO and PROGRESS CTO scores were not only associated with lower likelihood of angiographic success but also higher rates of long-term MACE. Compared with the scores of 0 to 2, J-CTO and PROGRESS CTO scores of ≥3 were associated with higher MACE. Multivariable analysis demonstrated that PROGRESS CTO scores of ≥3, male sex, and peripheral vascular disease were independent predictors of MACE. In conclusion, J-CTO and PROGRESS CTO scores are useful in predicting procedural success. In addition, the PROGRESS CTO score, and to a lesser degree J-CTO score, have predictive value for long-term outcomes in patients who underwent CTO PCI.

Abstract
BACKGROUND There are little published data reporting the effect of coronary artery chronic total occlusion (CTO) percutaneous coronary intervention (PCI) on the prognosis of elderly patients with identified CTOs. We sought to evaluate the clinical effect of CTO PCI on the prognosis of elderly patients with CTOs. METHODS A total of 445 consecutive patients diagnosed with a CTO by angiography from January 2011 to December 2013 were enrolled. We compared long-term clinical outcomes between the elderly group (≥75 years; n = 120, 27.0%), and the nonelderly group (<75 years; n = 325, 73.0%) as well as between patients with unopened CTOs and patients with CTOs who were recanalized by PCI either during the index hospitalization or at a staged procedure within 30 days after discharge from the index hospitalization. The primary endpoint was defined as the composite of hospitalization from angina, reinfarction, heart failure or repeat revascularization and cardiac death at the 3-year follow-up. RESULTS More elderly CTO patients had left main (LM) disease (25.0 versus 15.1%, P = 0.015), 3-vessel disease (96.4% versus 73.8%, P < 0.001) and a Japan-CTO score ≥2 (36.7% versus 23.7%, P = 0.006) than nonelderly CTO patients. Furthermore, elderly patients had a higher syntax score than nonelderly patients (27.0 [25.0, 30.0] versus 26.0 [23.0, 30.0], P = 0.006). PCI was attempted for 33 out of 135 CTO lesions (24.4%) in the elderly group, and 127 out of 378 lesions (33.6%) in the nonelderly group (P = 0.049); however, there were no statistically significant differences in the CTO PCI success rates between the 2 groups (69.7% versus 82.7%, P = 0.097). The 3-year cardiac mortality rate was 15.0% and 4.6% (P < 0.011) for the elderly and nonelderly groups, respectively. Elderly patients with CTOs who were recanalized by PCI and those with unopened CTOs exhibited comparable 3-year cardiac mortality rates (15.0% versus 16.0%, P = 1.000). There was no significant difference in primary endpoint incidence (25.0% versus 33.0%, P = 0.486). Multivariate analysis revealed that after corrections for baseline and procedural differences, right coronary artery CTO (odds ratio = 4.600, 95% CI: 1.320-16.031; P = 0.017) and LM disease combined with 3-vessel disease (odds ratio = 4.296, 95% CI: 1.166-15.831; P = 0.028) were independent predictors of 3-year cardiac mortality among elderly patients with CTOs. CONCLUSIONS Elderly patients with CTOs presented with seriously diseased coronary arteries and poor prognoses. CTO PCI did not seem to significantly improve long-term clinical outcomes among elderly patients with CTOs. Right coronary artery CTO and LM disease combined with 3-vessel disease might be independent predictors of 3-year cardiac mortality in elderly CTO patients.

Abstract
BACKGROUND The impact of percutaneous coronary intervention (PCI) on chronic total occlusion in patients with well-developed collaterals is not clear. METHODS AND RESULTS A total of 640 chronic total occlusion patients with collateral flow grade ≥2 were divided into 2 groups; chronic total occlusion patients either treated with PCI (the PCI group; n=305) or optimal medical therapy (the optimal medical therapy group; n=335). To adjust for potential confounders, a propensity score matching analysis was performed. Major clinical outcomes were compared between the 2 groups up to 5 years. In the entire population, the PCI group had a lower hazard of myocardial infarction (hazard ratio [HR], 0.177; P=0.039; 95% confidence interval [CI], 0.03-0.91) and the composite of total death or myocardial infarction (HR, 0.298; P=0.017; 95% CI, 0.11-0.80); however, it showed higher hazard of target lesion revascularization (HR, 3.942; P=0.003; 95% CI, 1.58-9.81) and target vessel revascularization (HR, 4.218; P=0.001; 95% CI, 1.85-9.60). After propensity score matching, a total of 158 matched pairs were generated. Although the PCI group showed a higher hazard of target lesion revascularization (HR, 2.868; P=0.027; 95% CI, 1.13-7.31) and target vessel revascularization (HR=2.62; P=0.022; 95% CI, 1.15-5.97), it still exhibited a lower incidence of the composite of total death or myocardial infarction (HR, 0.263; P=0.017; 95% CI, 0.087-0.790). The mean ejection fraction was improved from 47.8% to 51.6% (P<0.001) after PCI. CONCLUSIONS In our study, successful revascularization by PCI for chronic total occlusion lesions with well-developed collaterals was associated with lower incidence of death and myocardial infarction, improved left ventricular function, but increased repeat revascularization rate.

Abstract
Chronic total occlusions (CTOs) are routinely encountered during coronary angiography, but subsequent revascularization rates are low. This has likely been driven by a historical belief that there is minimal clinical benefit and poor success rates with a percutaneous coronary intervention (PCI). However, in the current era, with the development of new techniques and tools, experienced operators can perform CTO-PCI successfully in the majority of patients. The current indications and benefit of CTO-PCI remain a topic of controversy and debate. There is a growing body of predominantly nonrandomized studies reporting both short-term and long-term outcomes of CTO-PCI. Recent and upcoming randomized-controlled trials in this area will also potentially expand indications in both stable and patients with acute coronary syndrome. In this review, we will discuss the current evidence for CTO-PCI and also future directions in this field.
