Abstract
OBJECTIVE To study outcomes with use of percutaneous mechanical circulatory support (MCS) devices in chronic total occlusion (CTO) percutaneous coronary intervention (PCI). METHODS We examined characteristics and outcomes of 1598 CTO-PCIs performed from 2012-2017 at 12 high-volume centers. RESULTS Patient age was 66 ± 10 years; 86% were men. An MCS device was used electively in 69 procedures (4%) and urgently in 22 procedures (1%). The most commonly used elective MCS device was Impella 2.5 or CP (62%). Compared to patients without elective MCS, patients with elective MCS had higher prevalence of prior heart failure (55% vs 29%; P<.001), prior coronary artery bypass graft surgery (49% vs 35%; P=.02), and lower left ventricular ejection fraction (34 ± 14% vs 50 ± 14%; P<.001). MCS patients had a higher prevalence of moderate/ severe calcification (88% vs 55%; P<.001) and higher J-CTO scores (3.1 ± 1.2 vs 2.6 ± 1.2; P<.01), and a greater proportion underwent retrograde crossing attempts (55% vs 39%; P<.01). Despite more complex characteristics in MCS patients, technical success rates (88% vs 87%; P=.70) and procedural success rates (83% vs 87%; P=.32) were similar in the two groups. Use of elective MCS was associated with longer procedure and fluoroscopy times, and higher incidences of in-hospital major adverse cardiovascular events (8.7% vs 2.5%; P<.01) and bleeding (7.3% vs 1.0%; P<.001). CONCLUSION Elective MCS was used in 4% of patients undergoing CTO-PCI. Despite more complex clinical and angiographic characteristics, elective use of MCS in high-risk patients is associated with similar technical and procedural success rates, but higher risk of complications, compared to cases without elective MCS.

Abstract
INTRODUCTION We examined the impact of proximal vessel tortuosity on the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). METHODS The baseline clinical and angiographic characteristics and procedural outcomes of 1618 consecutive CTO-PCIs performed between 2012 and 2016 at 14 United States centers in 1589 patients were reviewed. RESULTS Mean patient age was 65.3 ± 10.0 years and 85% were men. Moderate/severe proximal vessel tortuosity was present in 35.7% of target lesions. Compared with non-tortuous lesions, tortuous lesions had longer length (30 mm [interquartile range, 20-50 mm] vs 28 mm [interquartile range, 16-40 mm]; P<.001), more proximal cap ambiguity (36% vs 28%; P<.01), and more frequent utilization of the retrograde approach (52% vs 37%; P<.001). Moderate/severe proximal vessel tortuosity was associated with lower technical success rates (84.1% vs 91.3%; P<.001) and procedural success rates (82.3% vs 89.9%; P<.001), but similar incidence of major cardiac adverse events (3.0% vs 2.5%; P=.59). Moderate/severe tortuosity was associated with longer procedure time and fluoroscopy time, higher air kerma radiation dose, and larger contrast volume. CONCLUSION In a contemporary multicenter registry, moderate/severe proximal vessel tortuosity was present in approximately one-third of target CTO lesions and was associated with more frequent use of the retrograde approach and lower success rates, but similar complication rates.

Abstract
BACKGROUND Patients with obstructive left main coronary artery disease are usually treated with coronary-artery bypass grafting (CABG). Randomized trials have suggested that drug-eluting stents may be an acceptable alternative to CABG in selected patients with left main coronary disease. METHODS We randomly assigned 1905 eligible patients with left main coronary artery disease of low or intermediate anatomical complexity to undergo either percutaneous coronary intervention (PCI) with fluoropolymer-based cobalt-chromium everolimus-eluting stents (PCI group, 948 patients) or CABG (CABG group, 957 patients). Anatomic complexity was assessed at the sites and defined by a Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) score of 32 or lower (the SYNTAX score reflects a comprehensive angiographic assessment of the coronary vasculature, with 0 as the lowest score and higher scores [no upper limit] indicating more complex coronary anatomy). The primary end point was the rate of a composite of death from any cause, stroke, or myocardial infarction at 3 years, and the trial was powered for noninferiority testing of the primary end point (noninferiority margin, 4.2 percentage points). Major secondary end points included the rate of a composite of death from any cause, stroke, or myocardial infarction at 30 days and the rate of a composite of death, stroke, myocardial infarction, or ischemia-driven revascularization at 3 years. Event rates were based on Kaplan-Meier estimates in time-to-first-event analyses. RESULTS At 3 years, a primary end-point event had occurred in 15.4% of the patients in the PCI group and in 14.7% of the patients in the CABG group (difference, 0.7 percentage points; upper 97.5% confidence limit, 4.0 percentage points; P=0.02 for noninferiority; hazard ratio, 1.00; 95% confidence interval, 0.79 to 1.26; P=0.98 for superiority). The secondary end-point event of death, stroke, or myocardial infarction at 30 days occurred in 4.9% of the patients in the PCI group and in 7.9% in the CABG group (P<0.001 for noninferiority, P=0.008 for superiority). The secondary end-point event of death, stroke, myocardial infarction, or ischemia-driven revascularization at 3 years occurred in 23.1% of the patients in the PCI group and in 19.1% in the CABG group (P=0.01 for noninferiority, P=0.10 for superiority). CONCLUSIONS In patients with left main coronary artery disease and low or intermediate SYNTAX scores by site assessment, PCI with everolimus-eluting stents was noninferior to CABG with respect to the rate of the composite end point of death, stroke, or myocardial infarction at 3 years.

Abstract
BACKGROUND High patient radiation dose during chronic total occlusion (CTO) percutaneous coronary intervention (PCI) might lead to procedural failure and radiation skin injury. METHODS We examined the association between several clinical and angiographic variables on patient air kerma (AK) radiation dose among 748 consecutive CTO PCIs performed at 9 experienced US centres between May 2012 and May 2015. RESULTS The mean age was 65 ± 10 years, 87% of patients were men, and 35% had previous coronary artery bypass graft surgery (CABG). Technical and procedural success was 92% and 90%, respectively. The median patient AK dose was 3.40 (interquartile range, 2.00-5.40) Gy and 34% of the patients received > 4.8 Gy (high radiation exposure). In univariable analysis male sex (P = 0.016), high body mass index (P < 0.001), history of hyperlipidemia (P = 0.023), previous CABG (P < 0.001), moderate or severe calcification (P < 0.001), tortuosity (P < 0.001), proximal cap ambiguity (P = 0.001), distal cap at a bifurcation (P = 0.006), longer CTO occlusion length (P < 0.001), blunt/no blunt stump (P < 0.001), and centre (P < 0.001) were associated with higher patient AK dose. In multivariable analysis high body mass index (P < 0.001), previous CABG (P = 0.005), moderate or severe calcification (P = 0.005), longer CTO occlusion length (P < 0.001), and centre (P < 0.001) were independently associated with higher patient AK dose. CONCLUSIONS Approximately 1 in 3 patients who undergo CTO PCI receive high AK radiation dose (> 4.8 Gy). Several baseline clinical and angiographic characteristics can help predict the likelihood of high radiation dose and assist with intensifying efforts to reduce radiation exposure for the patient and the operator.

Development and Validation of a Novel Scoring System for Predicting Technical Success of Chronic Total Occlusion Percutaneous Coronary Interventions: The PROGRESS CTO (Prospective Global Registry for the Study of Chronic Total Occlusion Intervention) Score. JACC Cardiovasc Interv 2016; 9:1-9. [PMID: 26762904 DOI: 10.1016/j.jcin.2015.09.022] [Citation(s) in RCA: 240] [Impact Index Per Article: 30.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/27/2015] [Revised: 08/10/2015] [Accepted: 09/10/2015] [Indexed: 01/16/2023]
Abstract
OBJECTIVES This study sought to develop a novel parsimonious score for predicting technical success of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) performed using the hybrid approach. BACKGROUND Predicting technical success of CTO PCI can facilitate clinical decision making and procedural planning. METHODS We analyzed clinical and angiographic parameters from 781 CTO PCIs included in PROGRESS CTO (Prospective Global Registry for the Study of Chronic Total Occlusion Intervention) using a derivation and validation cohort (2:1 sampling ratio). Variables with strong association with technical success in multivariable analysis were assigned 1 point, and a 4-point score was developed from summing all points. The PROGRESS CTO score was subsequently compared with the J-CTO (Multicenter Chronic Total Occlusion Registry in Japan) score in the validation cohort. RESULTS Technical success was 92.9%. On multivariable analysis, factors associated with technical success included proximal cap ambiguity (beta coefficient [b] = 0.88), moderate/severe tortuosity (b = 1.18), circumflex artery CTO (b = 0.99), and absence of "interventional" collaterals (b = 0.88). The resulting score demonstrated good calibration and discriminatory capacity in the derivation (Hosmer-Lemeshow chi-square = 2.633; p = 0.268, and receiver-operator characteristic [ROC] area = 0.778) and validation (Hosmer-Lemeshow chi-square = 5.333; p = 0.070, and ROC area = 0.720) subset. In the validation cohort, the PROGRESS CTO and J-CTO scores performed similarly in predicting technical success (ROC area 0.720 vs. 0.746, area under the curve difference = 0.026, 95% confidence interval = -0.093 to 0.144). CONCLUSIONS The PROGRESS CTO score is a novel useful tool for estimating technical success in CTO PCI performed using the hybrid approach.

Abstract
BACKGROUND Intravascular imaging can facilitate chronic total occlusion (CTO) percutaneous coronary intervention. METHODS AND RESULTS We examined the frequency of use and outcomes of intravascular imaging among 619 CTO percutaneous coronary interventions performed between 2012 and 2015 at 7 US centers. Mean age was 65.4±10 years and 85% of the patients were men. Intravascular imaging was used in 38%: intravascular ultrasound in 36%, optical coherence tomography in 3%, and both in 1.45%. Intravascular imaging was used for stent sizing (26.3%), stent optimization (38.0%), and CTO crossing (35.7%, antegrade in 27.9%, and retrograde in 7.8%). Intravascular imaging to facilitate crossing was used more frequently in lesions with proximal cap ambiguity (49% versus 26%, P<0.0001) and with retrograde as compared with antegrade-only cases (67% versus 31%, P<0.0001). Despite higher complexity (Japanese CTO score: 2.86±1.19 versus 2.43±1.19, P=0.001), cases in which imaging was used for crossing had similar technical and procedural success (92.8% versus 89.6%, P=0.302 and 90.1% versus 88.3%, P=0.588, respectively) and similar incidence of major cardiac adverse events (2.7% versus 3.2%, P=0.772). Use of intravascular imaging was associated with longer procedure (192 minutes [interquartile range 130, 255] versus 131 minutes [90, 192], P<0.0001) and fluoroscopy (71 minutes [44, 93] versus 39 minutes [25, 69], P<0.0001) time. CONCLUSIONS Intravascular imaging is frequently performed during CTO percutaneous coronary intervention both for crossing and for stent selection/optimization. Despite its use in more complex lesion subsets, intravascular imaging was associated with similar rates of technical and procedural success for CTO percutaneous coronary intervention.

Abstract
BACKGROUND Administration of a large amount of contrast volume during chronic total occlusion (CTO) percutaneous coronary intervention (PCI) may lead to contrast-induced nephropathy. METHODS We examined the association of clinical, angiographic and procedural variables with contrast volume administered during 1330 CTO-PCI procedures performed at 12 experienced United States centers. RESULTS Technical and procedural success was 90% and 88%, respectively, and mean contrast volume was 289 ± 138 mL. Approximately 33% of patients received >320 mL of contrast (high contrast utilization group). On univariable analysis, male gender (P=.01), smoking (P=.01), prior coronary artery bypass graft surgery (P=.04), moderate or severe calcification (P=.01), moderate or severe tortuosity (P=.04), proximal cap ambiguity (P=.01), distal cap at a bifurcation (P<.001), side branch at the proximal cap (P<.001), blunt/no stump (P=.01), occlusion length (P<.001), higher J-CTO score (P=.02), use of antegrade dissection and reentry or retrograde approach (P<.001), ad hoc CTO-PCI (P=.04), dual arterial access (P<.001), and 8 Fr guide catheters (P<.001) were associated with higher contrast volume; conversely, diabetes mellitus (P=.01) and in-stent restenosis (P=.01) were associated with lower contrast volume. On multivariable analysis, moderate/severe calcification (P=.04), distal cap at a bifurcation (P<.001), ad hoc CTO-PCI (P<.001), dual arterial access (P=.01), 8 Fr guide catheters (P=.02), and use of antegrade dissection/reentry or the retrograde approach (P<.001) were independently associated with higher contrast use, whereas diabetes (P=.02), larger target vessel diameter (P=.03), and presence of "interventional" collaterals (P<.001) were associated with lower contrast utilization. CONCLUSIONS Several baseline clinical, angiographic, and procedural characteristics are associated with higher contrast volume administration during CTO-PCI.

Abstract
BACKGROUND The use of saphenous vein grafts (SVGs) for retrograde native-vessel chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has received limited study. METHODS We retrospectively reviewed the medical records and coronary angiograms of retrograde CTO-PCI performed through an SVG at four United States institutions between 2012 and 2013. RESULTS During the study period, retrograde CTO-PCI was performed in 144 of 572 cases (25.2%) and retrograde CTO-PCI via SVG in 21 patients (14.6% of all retrograde cases). Mean age was 71 ± 7 years and 95.2% of the patients were men. The CTO target vessel was the right coronary (38%), circumflex (38%), and left anterior descending (24%) artery. Mean J-CTO score was 3.5 ± 1.0. The most common reentry technique was reverse controlled antegrade dissection and reentry. Technical and procedural success rates were 86% and 81%, respectively, with retrograde SVG-PCI attempts being successful in 67%. A major adverse cardiac event occurred in 2 patients (1 periprocedural myocardial infarction and 1 tamponade resulting in death). Median contrast volume, fluoroscopy time, and procedure time were 250 mL, 91.6 minutes, and 214 minutes, respectively. Two SVGs were coiled due to competitive flow after CTO recanalization. CONCLUSION Retrograde native-vessel CTO-PCI via SVG represents a small proportion of retrograde CTO-PCIs and was associated with high technical success rates, but may carry increased risk for complications.

Effect of Previous Failure on Subsequent Procedural Outcomes of Chronic Total Occlusion Percutaneous Coronary Intervention (from a Contemporary Multicenter Registry). Am J Cardiol 2016; 117:1267-71. [PMID: 26899493 DOI: 10.1016/j.amjcard.2016.01.021] [Citation(s) in RCA: 20] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 11/18/2015] [Revised: 01/22/2016] [Accepted: 01/22/2016] [Indexed: 12/18/2022]
Abstract
We sought to examine the impact of previous failure on the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI). We examined the clinical and angiographic characteristics and procedural outcomes of 1,213 consecutive patients who underwent 1,232 CTO PCIs from 2012 to 2015 at 12 US centers. Mean age was 65 ± 10 years, and 84.8% of patients were men. A previously failed attempt had been performed in 215 patients (17.5%). As compared with patients without previous CTO PCI failure, patients with previous failure had higher Multicenter CTO Registry in Japan CTO score (2.40 ± 1.13 vs 3.28 ± 1.29, p <0.0001) and were more likely to have in-stent restenosis (10.5% vs 28.4%, p <0.0001) and to undergo recanalization attempts using the retrograde approach (41% vs 50%, p = 0.011). Technical (90% vs 88%, p = 0.390) and procedural (89% vs 86%, p = 0.184) success were similar in the 2 study groups; however, median procedure time (125 vs 142 minutes, p = 0.026) and fluoroscopy time (45 vs 55 minutes, p = 0.015) were longer in the previous failure group. In conclusion, a previously failed CTO PCI attempt is associated with higher angiographic complexity, longer procedural duration, and fluoroscopy time, but not with the success and complication rates of subsequent CTO PCI attempts.

Abstract
BACKGROUND The performance of the Japan-chronic total occlusion (J-CTO) score in predicting success and efficiency of CTO percutaneous coronary intervention has received limited study. METHODS AND RESULTS We examined the records of 650 consecutive patients who underwent CTO percutaneous coronary intervention between 2011 and 2014 at 6 experienced centers in the United States. Six hundred and fifty-seven lesions were classified as easy (J-CTO=0), intermediate (J-CTO=1), difficult (J-CTO=2), and very difficult (J-CTO≥3). The impact of the J-CTO score on technical success and procedure time was evaluated with univariable logistic and linear regression, respectively. The performance of the logistic regression model was assessed with the Hosmer-Lemeshow statistic and receiver operator characteristic curves. Antegrade wiring techniques were used more frequently in easy lesions (97%) than very difficult lesions (58%), whereas the retrograde approach became more frequent with increased lesion difficulty (41% for very difficult lesions versus 13% for easy lesions). The logistic regression model for technical success demonstrated satisfactory calibration and discrimination (P for Hosmer-Lemeshow =0.743 and area under curve =0.705). The J-CTO score was associated with a 2-fold increase in the odds of technical failure (odds ratio 2.04, 95% confidence interval 1.52-2.80, P<0.001). Procedure time increased by ≈20 minutes for every 1-point increase of the J-CTO score (regression coefficient 22.33, 95% confidence interval 17.45-27.22, P<0.001). CONCLUSIONS J-CTO score was strongly associated with final success and efficiency in this study, supporting its expanded use in CTO interventions.

Use of antegrade dissection re-entry in coronary chronic total occlusion percutaneous coronary intervention in a contemporary multicenter registry. Int J Cardiol 2016; 214:428-37. [PMID: 27088405 DOI: 10.1016/j.ijcard.2016.03.215] [Citation(s) in RCA: 32] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 12/26/2015] [Revised: 03/28/2016] [Accepted: 03/29/2016] [Indexed: 10/22/2022]
Abstract
BACKGROUND We assessed efficacy and safety of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) using antegrade dissection re-entry (ADR). METHODS We examined outcomes of ADR among 1313 CTO PCIs performed at 11 US centers between 2012-2015. RESULTS 84.1% of patients were men. Prevalence of prior coronary artery bypass graft surgery was 34.3%. Overall technical and procedural success were 90.1% and 88.7%, respectively. In-hospital major adverse cardiovascular events (MACE) occurred in 31 patients (2.4%). ADR was used in 458 cases (34.9%), and was the first strategy in 169 cases (12.9%). ADR cases were angiographically more complex than non-ADR cases (mean J-CTO score: 2.8±1.2 vs. 2.4±1.2, p<0.001). ADR was performed using the CrossBoss catheter in 246 of 458 (53.7%) and the Stingray system in 251 ADR cases (54.8%). Compared with non-ADR cases, ADR cases had lower technical (86.9% vs. 91.8%, p=0.005) and procedural success (85.0% vs. 90.7%, p=0.002), but similar risk for MACE (2.9% vs. 2.2%, p=0.42). ADR was associated with longer procedure and fluoroscopy time, and higher patient air kerma dose and contrast volume (all p<0.001). After excluding retrograde cases, ADR and antegrade wire escalation (AWE) had similar technical success (92.7% vs. 94.2%, p=0.43), procedural success (91.8% vs. 94.1%, p=0.23), and MACE (2.1% vs. 0.6%, p=0.12). CONCLUSIONS ADR is used relatively frequently in contemporary CTO PCI, especially for challenging lesions and after failure of other strategies. ADR is associated with similar success rates and risk for complications as compared with AWE, and is important for achieving high procedural success.
