Abstract
Background Hybrid coronary revascularization (HCR) involves the integration of coronary artery bypass grafting (CABG) and percutaneous coronary intervention to treat multivessel coronary artery disease. Our objective was to perform a comparative analysis with long-term follow-up between HCR and conventional off-pump CABG. Methods and Results We compared all double off-pump CABG (n=216) and HCR (n=147; robotic-assisted minimally invasive direct CABG of the left internal thoracic artery to the left anterior descending artery and percutaneous coronary intervention to one of the non-left anterior descending vessels) performed at a single institution between March 2004 and November 2015. To adjust for the selection bias of receiving either off-pump CABG or HCR, we performed a propensity score analysis using inverse-probability weighting. Both groups had similar results in terms of re-exploration for bleeding, perioperative myocardial infarction, stroke, blood transfusion, in-hospital mortality, and intensive care unit length of stay. HCR was associated with a higher in-hospital reintervention rate (CABG 0% versus HCR 3.4%; P=0.03), lower prolonged mechanical ventilation (>24 hours) rate (4% versus 0.7%; P=0.02), and shorter hospital length of stay (8.1±5.8 versus 4.5±2.1 days; P<0.001). After a median follow-up of 81 (48-113) months for the off-pump CABG and 96 (53-115) months for HCR, the HCR group of patients had a trend toward improved survival (85% versus 96%; P=0.054). Freedom from any form of revascularization was similar between the 2 groups (92% versus 91%; P=0.80). Freedom from angina was better in the HCR group (73% versus 90%; P<0.001). Conclusions HCR seems to provide, in selected patients, a shorter postoperative recovery, with similar excellent short- and long-term outcomes when compared with standard off-pump CABG.

Abstract
BACKGROUND Percutaneous coronary intervention (PCI) of coronary bifurcation lesions (CBL) remains a challenge in contemporary practice due to the procedural and technical difficulties involved. We sought to review the current evidence on the safety and clinical outcomes of dedicated bifurcation stent (DBS) implantation in comparison with established treatment strategies for CBL-PCI. METHODS We conducted a comprehensive search to identify randomized control trials (RCTs) reporting 1-year clinical and angiographic outcomes of patients undergoing CBL-PCI with DBS vs conventional CBL-PCI strategies. Random-effects meta-analyses were performed to estimate the effect of DBS compared with conventional CBL-PCI using aggregate data. RESULTS A total of 5 RCTs comprising 1249 participants met the inclusion criteria. The use of DBS was comparable to conventional stenting techniques in terms of major adverse cardiovascular event (MACE) rate (odds ratio [OR], 1.28; 95% confidence interval [CI], 0.90- 1.82; I²=0%), all-cause mortality (OR, 0.80; 95% CI, 0.31-2.07; I²=0%), cardiac mortality (OR, 0.16; 95% CI, 0.02-1.39; I²=0%), myocardial infarction (OR, 1.26; 95% CI, 0.84-1.89; I²=0%), definite stent thrombosis (OR, 1.75; 95% CI, 0.36-8.52; I²=0%), cumulative target-lesion revascularization (OR, 1.39; 95% CI, 0.85-2.27; I²=0%), clinically driven target-lesion revascularization (OR, 1.23; 95% CI, 0.68-2.22; I²=0%), or target-vessel revascularization (OR, 1.43; 95% CI, 0.92-2.22; I²=0%). CONCLUSION The present analysis suggests that CBL-PCI with DBS may be associated with similar 1-year clinical and angiographic outcomes compared with conventional CBL-PCI strategies. However, the low quality of evidence and limited follow-up warrant further studies to ascertain any significant differences in patient-important outcomes before the adoption of DBS into routine CBL-PCI practice.

Abstract
BACKGROUND In patients with ST-segment elevation myocardial infarction (STEMI), percutaneous coronary intervention (PCI) of the culprit lesion reduces the risk of cardiovascular death or myocardial infarction. Whether PCI of nonculprit lesions further reduces the risk of such events is unclear. METHODS We randomly assigned patients with STEMI and multivessel coronary artery disease who had undergone successful culprit-lesion PCI to a strategy of either complete revascularization with PCI of angiographically significant nonculprit lesions or no further revascularization. Randomization was stratified according to the intended timing of nonculprit-lesion PCI (either during or after the index hospitalization). The first coprimary outcome was the composite of cardiovascular death or myocardial infarction; the second coprimary outcome was the composite of cardiovascular death, myocardial infarction, or ischemia-driven revascularization. RESULTS At a median follow-up of 3 years, the first coprimary outcome had occurred in 158 of the 2016 patients (7.8%) in the complete-revascularization group as compared with 213 of the 2025 patients (10.5%) in the culprit-lesion-only PCI group (hazard ratio, 0.74; 95% confidence interval [CI], 0.60 to 0.91; P = 0.004). The second coprimary outcome had occurred in 179 patients (8.9%) in the complete-revascularization group as compared with 339 patients (16.7%) in the culprit-lesion-only PCI group (hazard ratio, 0.51; 95% CI, 0.43 to 0.61; P<0.001). For both coprimary outcomes, the benefit of complete revascularization was consistently observed regardless of the intended timing of nonculprit-lesion PCI (P = 0.62 and P = 0.27 for interaction for the first and second coprimary outcomes, respectively). CONCLUSIONS Among patients with STEMI and multivessel coronary artery disease, complete revascularization was superior to culprit-lesion-only PCI in reducing the risk of cardiovascular death or myocardial infarction, as well as the risk of cardiovascular death, myocardial infarction, or ischemia-driven revascularization.

Abstract
OBJECTIVE To assess the effects of different oral antithrombotic drugs that prevent saphenous vein graft failure in patients undergoing coronary artery bypass graft surgery. DESIGN Systematic review and network meta-analysis. DATA SOURCES Medline, Embase, Web of Science, CINAHL, and the Cochrane Library from inception to 25 January 2019. ELIGIBILITY CRITERIA: for selecting studies Randomised controlled trials of participants (aged ≥18) who received oral antithrombotic drugs (antiplatelets or anticoagulants) to prevent saphenous vein graft failure after coronary artery bypass graft surgery. MAIN OUTCOME MEASURES The primary efficacy endpoint was saphenous vein graft failure and the primary safety endpoint was major bleeding. Secondary endpoints were myocardial infarction and death. RESULTS This review identified 3266 citations, and 21 articles that related to 20 randomised controlled trials were included in the network meta-analysis. These 20 trials comprised 4803 participants and investigated nine different interventions (eight active and one placebo). Moderate certainty evidence supports the use of dual antiplatelet therapy with either aspirin plus ticagrelor (odds ratio 0.50, 95% confidence interval 0.31 to 0.79, number needed to treat 10) or aspirin plus clopidogrel (0.60, 0.42 to 0.86, 19) to reduce saphenous vein graft failure when compared with aspirin monotherapy. The study found no strong evidence of differences in major bleeding, myocardial infarction, and death among different antithrombotic therapies. The possibility of intransitivity could not be ruled out; however, between-trial heterogeneity and incoherence were low in all included analyses. Sensitivity analysis using per graft data did not change the effect estimates. CONCLUSIONS The results of this network meta-analysis suggest an important absolute benefit of adding ticagrelor or clopidogrel to aspirin to prevent saphenous vein graft failure after coronary artery bypass graft surgery. Dual antiplatelet therapy after surgery should be tailored to the patient by balancing the safety and efficacy profile of the drug intervention against important patient outcomes. STUDY REGISTRATION PROSPERO registration number CRD42017065678.

Abstract
BACKGROUND Rotational atherectomy (RA) has been traditionally performed via the transfemoral approach, mostly utilizing large guide catheters (≥7 Fr), which can accommodate the passage of large burrs (≥1.75 mm). However, contemporary data show that using smaller sheath and catheter sizes reduces the risk of procedural access-site related complications. Therefore, the aim of this study was to assess the feasibility of performing RA using smaller burrs and subsequently smaller-sized sheath catheters. METHODS A total of 220 patients underwent RA procedures between January 2011 and July 2017. We compared 162 patients who underwent RA using a maximal burr size of 1.5 mm (small-burr group) with 58 patients who underwent RA using burrs >1.5 mm in diameter (large-burr group). Clinical, procedural, safety, and feasibility data were evaluated and compared between the two groups. RESULTS Baseline characteristics of the two groups were quite similar other than a higher prevalence of smoking (21.0% vs 5.2%; P<.01) and a lower body weight (80.9 ± 17.5 kg vs 86.8 ± 17.2 kg; P=.03) in the small-burr group vs the large-burr group. The indications for the procedure for the small-burr group vs large-burr group were stable angina in 53% vs 62%, unstable angina in 16% vs 17%, non-ST elevation myocardial infarction (MI) in 26% vs 17%, and ST-elevation MI in 3.7% vs 3.4%, respectively (P=NS for all). The target-vessel (TV) diameter was significantly larger in the large-burr group vs the small-burr group (3.5 ± 0.3 mm vs 3.2 ± 0.5 mm, respectively; P<.01). Importantly, a sheath size >6 Fr was used in 56.0% of the small-burr group vs 89.5% of the large-burr group (P<.01). Moreover, in 53% of the small-burr group, a guide catheter >6 Fr was used. Radial access was used in 33% of the small-burr group and 17% of the large-burr group (P=.03). Procedural success was achieved in 93% of the small-burr group and 100% of the large-burr group (P=.07). CONCLUSION In the majority of cases, RA can be successfully performed using smaller-sized burrs while achieving a high procedural success rate. Notably, our study also highlights the overuse of large sheaths and catheters to deliver small burrs. These results further support the contemporary strategy of using 6 Fr guide catheters, thereby increasing the possibility of using the radial approach for more complex interventional procedures.

Abstract
BACKGROUND Robust comparisons between oral P2Y12 inhibitors (clopidogrel, prasugrel, ticagrelor) in ST-elevation myocardial infarction (STEMI) patients who undergo primary percutaneous coronary intervention are lacking. We sought to evaluate outcomes on the basis of P2Y12 inhibitor therapy in patients from the Thrombectomy With PCI Versus PCI Alone in Patients With STEMI Undergoing Primary PCI (TOTAL) trial. METHODS We grouped 9932 patients according to P2Y12 inhibitor at hospital discharge: clopidogrel (n = 6500; 65.5%), prasugrel (n = 1244; 12.5%), or ticagrelor (n = 2188; 22.0%). The primary composite end point of cardiovascular death, recurrent myocardial infarction, cardiogenic shock, or New York Heart Association class IV heart failure was examined at 1 year. Secondary efficacy and safety end points were also assessed. Cox proportional hazard ratios were determined and adjusted for confounders via propensity scoring. RESULTS Baseline characteristics differing between the 3 groups were mainly age 75 years or older, diabetes, and previous stroke. After adjustment, ticagrelor use was associated with a lower rate of the primary composite outcome compared with clopidogrel (adjusted hazard ratio [aHR], 0.72; 95% confidence interval [CI], 0.57-0.91; P < 0.02) and prasugrel (aHR, 0.65; 95% CI, 0.48-0.89; P = 0.02). Prasugrel use was not associated with a lower rate of the primary outcome compared with clopidogrel (aHR, 1.09; 95% CI, 0.86-1.39; P > 0.99). Neither prasugrel nor ticagrelor were associated with increased risk of stroke compared with clopidogrel. Compared with clopidogrel, ticagrelor was associated with significantly lower rates of major bleeding. CONCLUSIONS In this observational analysis of STEMI patients who underwent primary percutaneous coronary intervention, ticagrelor was associated with improved outcomes compared with clopidogrel and prasugrel. An appropriately powered randomized trial is needed to confirm these findings.

Abstract
AIMS Spontaneous coronary artery dissection (SCAD) was underdiagnosed and poorly understood for decades. It is increasingly recognized as an important cause of myocardial infarction (MI) in women. We aimed to assess the natural history of SCAD, which has not been adequately explored. METHODS AND RESULTS We performed a multicentre, prospective, observational study of patients with non-atherosclerotic SCAD presenting acutely from 22 centres in North America. Institutional ethics approval and patient consents were obtained. We recorded baseline demographics, in-hospital characteristics, precipitating/predisposing conditions, angiographic features (assessed by core laboratory), in-hospital major adverse events (MAE), and 30-day major adverse cardiovascular events (MACE). We prospectively enrolled 750 SCAD patients from June 2014 to June 2018. Mean age was 51.8 ± 10.2 years, 88.5% were women (55.0% postmenopausal), 87.7% were Caucasian, and 33.9% had no cardiac risk factors. Emotional stress was reported in 50.3%, and physical stress in 28.9% (9.8% lifting >50 pounds). Predisposing conditions included fibromuscular dysplasia 31.1% (45.2% had no/incomplete screening), systemic inflammatory diseases 4.7%, peripartum 4.5%, and connective tissue disorders 3.6%. Most were treated conservatively (84.3%), but 14.1% underwent percutaneous coronary intervention and 0.7% coronary artery bypass surgery. In-hospital composite MAE was 8.8%; peripartum SCAD patients had higher in-hospital MAE (20.6% vs. 8.2%, P = 0.023). Overall 30-day MACE was 8.8%. Peripartum SCAD and connective tissue disease were independent predictors of 30-day MACE. CONCLUSION Spontaneous coronary artery dissection predominantly affects women and presents with MI. Despite majority of patients being treated conservatively, survival was good. However, significant cardiovascular complications occurred within 30 days. Long-term follow-up and further investigations on management are warranted.

Abstract
BACKGROUND Coronary angiography and intervention to saphenous venous grafts (SVGs) remain challenging. This study aimed to investigate the feasibility and safety of the radial approach compared to femoral access in a large cohort of patients undergoing SVG angiography and intervention. METHODS Data from 1,481 patients from Canada, United States, and Spain who underwent procedures between 2010 and 2016 were collected. Patients must have undergone SVG coronary angiography and/or intervention. Demographics, procedural data, and in-hospital complications were recorded. RESULTS Procedures were undertaken by either the radial (n = 863, 211 intervention) or femoral (n = 618, 260 intervention) approach. The mean number of SVGs per patient was similar between groups (radial 2.3 ± 0.7 vs femoral 2.6 ± 1.1, P = .61), but the radial group required a fewer number of catheters (2.6 ± 1.7 vs 4.1 ± 1.1, P < .001). Fluoroscopy time was comparable between groups, and there was a trend toward lower contrast volume in the radial group (P = .045). Overall, the total dose of heparin was significantly higher in the radial group (P < .001); however, radial patients experienced significantly less access-site bleeding complications (P < .001). Outpatients undergoing radial SVG interventions had a higher likelihood of a same-day discharge home (P < .001). CONCLUSIONS Radial access for SVG angiography and intervention is safe and feasible, without increasing fluoroscopy time. In experienced centers, radial access was associated with fewer catheters used, lower contrast volume, and lower rate of vascular access-site bleeding complications. Moreover, outpatients undergoing SVG percutaneous coronary intervention though the radial approach had a higher likelihood of a same-day discharge home.

Abstract
The long-term pharmacodynamic effects of Ticagrelor versus Clopidogrel in patients undergoing early percutaneous coronary intervention (PCI) after fibrinolytic therapy is unknown. From May 2014 to August 2016, 212 patients undergoing PCI within 24 h of Tenecteplase (TNK), Aspirin, and Clopidogrel for ST-elevated myocardial infarction (STEMI) were randomized at four Canadian sites to receive additional Clopidogrel or Ticagrelor initiated prior to PCI. The platelet reactivity units (PRU) were measured with the VerifyNow Assay before study drug administration (baseline), at 4 and 24 h post PCI, and follow-up appointment. A mixed-model analysis with time as the repeated measure and drug as the between-subjects factor was calculated using 2 separate 1 × 4 ANOVAs, with students t-tests used to compare drugs within each time point. Complete clinical follow-up data (median 115.0 days; IQR 80.3-168.8) was available in 50 patients (23.6%) randomized to either Clopidogrel (n = 23) or Ticagrelor (n = 27). Analyses revealed significant decreases in PRU from baseline to 4 h (261.4 vs. 71.7; Mdiff = - 189.7; p < 0.001) to 24 h (71.7 vs. 27.7; Mdiff = - 44.0; p < 0.001) to end of follow-up (27.7 vs.17.9; Mdiff = - 9.9. p = 0.016) for those randomized to Ticagrelor and significant decreases in PRU only from baseline to 4 h (271.3 vs. 200.8; Mdiff = - 70.5, p = < 0.001) in patients receiving Clopidogrel, and a significantly greater proportion of patients with adequate platelet inhibition (PRU < 208) on long-term follow-up (Clopidogrel, 82.6% vs. Ticagrelor, 100.0%; p = 0.038). Our results demonstrate that in patients undergoing PCI within 24 h of fibrinolysis for STEMI, Ticagrelor provides prolonged platelet inhibition compared with Clopidogrel.
