RESUMEN
BACKGROUND: The frequency of and relationship between hospital readmissions and outcomes after revascularization for left main coronary artery disease (LMCAD) are unknown. OBJECTIVES: The purpose of this study was to study the incidence, predictors, and clinical impact of readmissions following percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) for LMCAD. METHODS: In the EXCEL (XIENCE Versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) trial, 1,905 patients with LMCAD were randomized to PCI vs CABG. The cumulative incidence of readmissions was analyzed with multivariable Anderson-Gill and joint frailty models to account for recurrent events and the competing risk of death. The impact of readmission on subsequent mortality within 5-year follow-up was determined in a time-adjusted Cox proportional hazards model. RESULTS: Within 5 years, 1,868 readmissions occurred in 851 of 1,882 (45.2%) hospital survivors (2.2 ± 1.9 per patient with readmission[s], range 1-16), approximately one-half for cardiovascular causes and one-half for noncardiovascular causes (927 [49.6%] and 941 [50.4%], respectively). One or more readmissions occurred in 463 of 942 (48.6%) PCI patients vs 388 of 940 (41.8%) CABG patients (P = 0.003). After multivariable adjustment, PCI remained an independent predictor of readmission (adjusted HR: 1.22; 95% CI: 1.10-1.35; P < 0.0001), along with female sex, comorbidities, and the extent of CAD. Readmission was independently associated with subsequent all-cause death, with interaction testing indicating a higher risk after PCI than CABG (adjusted HR: 5.72; 95% CI: 3.42-9.55 vs adjusted HR: 2.72; 95% CI: 1.64-4.88, respectively; Pint = 0.03). CONCLUSIONS: In the EXCEL trial, readmissions during 5-year follow-up after revascularization for LMCAD were common and more frequent after PCI than CABG. Readmissions were associated with an increased risk of all-cause death, more so after PCI than with CABG.

BACKGROUND: The relative risks for different periprocedural major adverse events (MAE) after percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG) on subsequent mortality have not been described. OBJECTIVES: The aim of this study was to assess the association between periprocedural MAE occurring within 30 days postprocedure and early and late mortality after left main coronary artery revascularization by PCI and CABG. METHODS: In the EXCEL (Evaluation of XIENCE Versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) trial, patients with left main disease were randomized to PCI vs CABG. The associations between 12 prespecified nonfatal MAE and subsequent 5-year all-cause and cardiovascular death in 1,858 patients were examined using logistic regression. RESULTS: One or more nonfatal MAE occurred in 111 of 935 patients (11.9%) after PCI and 419 of 923 patients (45.4%) after CABG (P < 0.0001). Patients with MAE were older and had more baseline comorbidities. Within 5 years, all-cause death occurred in 117 and 87 patients after PCI and CABG, respectively. Experiencing an MAE was a strong independent predictor of 5-year mortality after both PCI (adjusted OR: 4.61; 95% CI: 2.71-7.82) and CABG (adjusted OR: 3.25; 95% CI: 1.95-5.41). These associations were present within the first 30 days and between 30 days and 5 years postprocedure. Major or minor bleeding with blood transfusion ≥2 U was an independent predictor of 5-year mortality after both procedures. Stroke, unplanned revascularization for ischemia, and renal failure were significantly associated with mortality only after CABG. CONCLUSIONS: In the EXCEL trial, nonfatal periprocedural MAE were strongly associated with early and late mortality after both PCI and CABG for left main disease.

BACKGROUND: The EXCEL trial reported similar five-year rates of the primary composite outcome of death, myocardial infarction (MI), or stroke after percutaneous coronary intervention (PCI) compared with coronary artery bypass grafting (CABG) for treatment of obstructive left main coronary artery disease (LMCAD). AIMS: We sought to determine whether these outcomes remained consistent regardless of geography of enrolment. METHODS: We performed a prespecified subgroup analysis based on regional enrolment. RESULTS: Among 1,905 patients randomised to PCI (n=948) or CABG (n=957), 1,075 (56.4%) were recruited at 52 European Union (EU) centres, and 752 (39.5%) were recruited at 67 North American (NA) centres. EU versus NA patients varied according to numerous baseline demographics, anatomy, pharmacotherapy and procedural characteristics. Nonetheless, the relative rates of the primary endpoint after PCI versus CABG were consistent across EU versus NA centres at 30 days and 5 years. However, NA participants had substantially higher late rates of ischaemia-driven revascularisation (IDR) after PCI, driven predominantly by the need for greater target vessel and lesion revascularisation. This culminated in a significant difference in the relative risk of the secondary composite outcome of death, MI, stroke, or IDR at 5 years (pinteraction=0.02). CONCLUSIONS: In the EXCEL trial, the relative risks for the 30-day and five-year primary composite outcome of death, MI or stroke after PCI versus CABG were consistent irrespective of geography. However, five-year rates of IDR after PCI were significantly higher in NA centres, a finding the Heart Team and patients should consider when making treatment decisions. ClinicalTrials.gov identifier: NCT01205776.

BACKGROUND: There is a paucity of data regarding the effect of inhibition of the renin-angiotensin system on outcomes after percutaneous coronary intervention (PCI) and coronary artery bypass grafting (CABG). We sought to examine long-term outcomes of patients with left main coronary disease (LMCAD) randomized to PCI with fluoropolymer-based cobalt-chromium everolimus-eluting stents or CABG according to treatment at discharge with angiotensin-converting enzyme inhibitors (ACEI) or angiotensin receptor blockers (ARB) in the large-scale, multicenter, randomized EXCEL trial. METHODS: EXCEL randomized 1905 patients with LMCAD of low and intermediate anatomical complexity (visually-assessed SYNTAX score ≤32) to PCI (n = 948) versus CABG (n = 957). Patients were categorized according to whether they were treated with ACEI/ARB at discharge; their outcomes from discharge to 5 years were examined using multivariable logistic regression with an offset for follow-up time. RESULTS: Among 1775 patients discharged alive with known ACEI/ARB treatment status, 896 (50.5%) were treated with one of these agents. Among those treated with ACEI/ARB, the 5-year rate of all-cause death was similar after PCI or CABG (10.7% versus 9.8% respectively, adjOR, 0.94; 95% CI, 0.56-1.57) in contrast to patients not treated with ACEI/ARB (15.0% versus 7.8%, respectively, adjOR, 2.20; 95% CI, 1.32-3.67) (Pinteraction = 0.02). Significant interactions between treatment arm (PCI versus CABG) and ACEI/ARB treatment status were also found for cardiovascular death (Pinteraction = 0.03), ischemia-driven revascularization (Pinteraction = 0.03), target vessel revascularization (Pinteraction = 0.007) and target vessel failure (Pinteraction = 0.0009). CONCLUSION: In the EXCEL trial, the postdischarge rates of death and revascularization after 5 years were similar after PCI and CABG in patients with LMCAD treated with ACEI/ARB at discharge. In contrast, event rates were higher after PCI versus CABG in those not so treated.

BACKGROUND: The outcomes of distal radial access (dRA) in chronic total occlusion percutaneous coronary intervention (CTO-PCI) have received limited study. METHODS: We compared the clinical, angiographic, and procedural characteristics of 120 CTO-PCIs performed via dRA access with 2625 CTO-PCIs performed via proximal radial access (pRA) in a large, multicenter registry. RESULTS: The dRA group had lower mean PROGRESS-CTO score than the pRA group (1.0 ± 1 vs 1.2 ± 1, respectively; P=.05), while J-CTO score (2.4 ± 1.2 vs 2.3 ± 1.3; P=.43) and PROGRESS-CTO Complications score (2.8 ± 1.8 vs 2.6 ± 1.9; P=.16) were similar in the dRA vs pRA groups, respectively. Technical success was similar in the 2 groups (90% dRA vs 86% pRA; P=.14). Concomitant use of femoral access did not alter procedural success. The incidence of major periprocedural adverse cardiac events was similar in the 2 groups (0.8% dRA vs 2.4% pRA; P=.26), whereas the incidence of tamponade requiring pericardiocentesis was lower with dRA (0% dRA vs 4.69% pRA; P<.001), as was air kerma radiation dose (median, 1.7 Gy; interquartile range [IQR], 0.97-2.63 Gy in the dRA group vs median, 2.27 Gy; IQR, 1.2-3.9 Gy in the pRA group; P<.001). CONCLUSIONS: Use of dRA in CTO-PCI is associated with similar procedural success and risk of complications as compared with pRA.

OBJECTIVES: We compared the effect of bivalirudin or heparin and use or nonuse of glycoprotein IIb/IIIa inhibitors (GPI) on the outcome of left main coronary artery (LMCA) percutaneous coronary intervention (PCI) in the randomized EXCEL trial. BACKGROUND: The optimal antithrombotic regimen to support PCI of the LMCA remains controversial because of low representation of this subset in clinical trials. METHODS: The PCI cohort (n = 928) in EXCEL was divided according to bivalirudin versus heparin antithrombin treatment and compared for the primary composite endpoint of death, myocardial infarction (MI), or stroke at 30 days and 5 years. RESULTS: Bivalirudin was used in 319 patients (34.4%). The composite endpoint at 30 days occurred in 7.2% versus 3.8% bivalirudin and heparin patients, respectively, p = .02; at 5 years, the composite endpoint occurred in 26.3% versus 19.9% bivalirudin and heparin patients, respectively, p = .02. Major bleeding was more frequent in bivalirudin patients (4.1% versus 1.3%, p = .008). There were no differences in stent thrombosis between the groups. Bivalirudin use was an independent predictor of the 30-day composite endpoint (OR 2.88, 95% CI 1.28-6.48, p = .01) but not of the 5-year composite endpoint (OR 1.30, 95% CI 0.84-2.02, p = .23). GPI use was infrequent (n = 67, 7.2%) and was not associated with adverse outcomes. CONCLUSION: Among patients undergoing LMCA PCI in the EXCEL trial, procedural use of bivalirudin was associated with greater rates of periprocedural MI and the 30-day composite endpoint without reducing bleeding complications. Five-year outcomes were similar. GPIs were used infrequently and were not associated with clinical outcomes.

OBJECTIVES: We examined outcomes according to lesion preparation strategy (LPS) in patients with left main coronary artery (LMCA) percutaneous coronary intervention (PCI) in the EXCEL trial. BACKGROUND: The optimal LPS for LMCA PCI is unclear. METHODS: We categorized LPS hierarchically (high to low) as: (a) rotational atherectomy (RA); (b) cutting or scoring balloon (CSB); (c) balloon angioplasty (BAL); and d) direct stenting (DIR). The primary endpoint was 3-year MACE; all-cause death, stroke, or myocardial infarction. RESULTS: Among 938 patients undergoing LMCA PCI, RA was performed in 6.0%, CSB 9.5%, BAL 71.3%, and DIR 13.2%. In patients treated with DIR, BAL, CSB, and RA, respectively, there was a progressive increase in SYNTAX score, LMCA complex bifurcation, trifurcation or calcification, number of stents, and total stent length. Any procedural complication occurred in 10.4% of cases overall, with the lowest rate in the DIR (7.4%) and highest in the RA group (16.1%) (ptrend = .22). There were no significant differences in the 3-year rates of MACE (from RA to DIR: 17.9%, 20.2%, 14.5%, 14.7%; p = .50) or ischemia-driven revascularization (from RA to DIR: 16.8%, 10.8%, 12.3%, 14.2%; p = .65). The adjusted 3-year rates of MACE did not differ according to LPS. CONCLUSIONS: The comparable 3-year outcomes suggest that appropriate lesion preparation may be able to overcome the increased risks of complex LMCA lesion morphology.

BACKGROUND: We examined guidewire and microcatheter utilization during chronic total occlusion (CTO) percutaneous coronary intervention (PCI). METHODS: We examined device utilization in 2,968 CTO PCIs performed in 2,936 patients at 19 US and two international center between January 2016 and January 2019. RESULTS: The median number of antegrade guidewires used per case declined (5 in 2016 vs 3 in 2019) and was higher in higher complexity lesions (2 in J-CTO 0 vs. 8 in J-CTO 4 or 5 score). In antegrade-only procedures, the most frequently used guidewires were the Pilot 200 (Abbott Vascular, 37%), Fielder XT (Asahi Intecc, 25%) and Gaia third (Asahi Intecc, 18%), while the most commonly used microcatheters were the Turnpike Spiral (Vascular Solutions, 18%) and Turnpike (Vascular Solutions, 16%). Compared with 2012-2015, during 2016-2019 use of novel equipment such as the Gaia guidewires and the Turnpike microcatheters led to decreased use of Confianza Pro 12 (Asahi Intecc) wire and Corsair (Asahi Intecc) family of microcatheters. In retrograde cases, the guidewires most commonly used were the Sion (44%), Pilot 200 (27%) and Fielder FC (26%), while the Corsair/Corsair Pro, Turnpike LP (Vascular Solutions) and Caravel (Asahi Intecc) were the most frequently used microcatheters for collateral crossing (29%, 26% and 22%, respectively). CONCLUSIONS: The most commonly used guidewires during CTO PCI are polymer-jacketed guidewires and the most commonly used microcatheters are torquable microcatheters.

Prior studies in patients with noncomplex coronary artery disease have demonstrated the safety of percutaneous coronary intervention (PCI) in the outpatient setting. We sought to examine the outcomes of outpatient PCI in patients with unprotected left main coronary artery disease (LMCAD). In the EXCEL trial, 1905 patients with LMCAD and site-assessed low or intermediate SYNTAX scores were randomized to PCI with everolimus-eluting stents versus coronary artery bypass grafting. The primary end point was major adverse cardiovascular events (MACE; the composite of death, stroke, or myocardial infarction). In this sub-analysis, outcomes at 30 days and 5 years were analyzed according to whether PCI was performed in the outpatient versus inpatient setting. Among 948 patients with LMCAD assigned to PCI, 935 patients underwent PCI as their first procedure, including 100 (10.7%) performed in the outpatient setting. Patients who underwent outpatient compared with inpatient PCI were less likely to have experienced recent myocardial infarction. Distal left main bifurcation disease involvement and SYNTAX scores were similar between the groups. Comparing outpatient to inpatient PCI, there were no significant differences in MACE at 30 days (4.0% vs 5.0% respectively, adjusted OR 0.52 95% CI 0.12 to 2.22; pâ¯=â¯0.38) or 5 years (20.6% vs 22.1% respectively, adjusted OR 0.72, 95% CI 0.40 to 1.29; pâ¯=â¯0.27). Similar results were observed in patients with distal left main bifurcation lesions. In conclusion, in the EXCEL trial, outpatient PCI of patients with LMCAD was not associated with an excess early or late hazard of MACE. These data suggest that outpatient PCI may be safely performed in select patients with LMCAD.

BACKGROUND: Varying definitions of procedural myocardial infarction (PMI) are in widespread use. OBJECTIVES: This study sought to determine the rates and clinical relevance of PMI using different definitions in patients with left main coronary artery disease randomized to percutaneous coronary intervention (PCI) versus coronary artery bypass grafting (CABG) surgery in the EXCEL (Evaluation of XIENCE versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) trial. METHODS: The pre-specified protocol definition of PMI (PMIProt) required a large elevation of creatine kinase-MB (CK-MB), with identical threshold for both procedures. The Third Universal Definition of MI (types 4a and 5) (PMIUD) required lesser biomarker elevations but with supporting evidence of myocardial ischemia, different after PCI and CABG. For the PMIUD, troponins were used preferentially (available in 49.5% of patients), CK-MB otherwise. The multivariable relationship between each PMI type and 5-year mortality was determined. RESULTS: PMIProt occurred in 34 of 935 (3.6%) patients after PCI and 56 of 923 (6.1%) patients after CABG (difference -2.4%; 95% confidence interval [CI]: -4.4% to -0.5%; p = 0.015). The corresponding rates of PMIUD were 37 (4.0%) and 20 (2.2%), respectively (difference 1.8%; 95% CI: 0.2% to 3.4%; p = 0.025). Both PMIProt and PMIUD were associated with 5-year cardiovascular mortality (adjusted hazard ratio [HR]: 2.18 [95% CI: 1.13 to 4.23] and 2.87 [95% CI: 1.44 to 5.73], respectively). PMIProt was associated with a consistent hazard of cardiovascular mortality after both PCI and CABG (pinteraction = 0.86). Conversely, PMIUD was strongly associated with cardiovascular mortality after CABG (adjusted HR: 11.94; 95% CI: 4.84 to 29.47) but not after PCI (adjusted HR: 1.14; 95% CI: 0.35 to 3.67) (pinteraction = 0.004). Results were similar for all-cause mortality and with varying PMIUD biomarker definitions. Only large biomarker elevations (CK-MB ≥10× upper reference limit and troponin ≥70× upper reference limit) were associated with mortality. CONCLUSIONS: The rates of PMI after PCI and CABG vary greatly with different definitions. In the EXCEL trial, the pre-specified PMIProt was associated with similar hazard after PCI and CABG, whereas PMIUD was strongly associated with mortality after CABG but not after PCI.

BACKGROUND: The impact of intravascular ultrasound (IVUS) utilization for stent optimization on the long-term outcomes in chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has received limited study. METHODS: We examined the outcomes of CTO-PCI with and without IVUS use for stent optimization in 922 CTO-PCIs performed between 2012 and 2019 at 12 United States centers. Major adverse cardiac event (MACE) was defined as the composite of cardiac death, acute coronary syndrome, and target-vessel revascularization. RESULTS: IVUS was used in 344 procedures (37%) for stent optimization. Mean patient age was 65 ± 10 years and 83% were men. Patients in the IVUS group were less likely to have a prior myocardial infarction (39% vs 50%; P<.01), more likely to undergo right coronary artery CTO-PCI (49% vs 55%; P=.01), and had higher mean J-CTO score (2.6 ± 1.1 vs 2.4 ± 1.2; P=.04). The final crossing strategy in patients in the IVUS group was less likely to be antegrade wire escalation (54% vs 57%) and more likely to be retrograde (29% vs 21%; P<.01). Median follow-up was 141 days (interquartile range, 30-365 days). The incidence of 12-month MACE was similar in the IVUS and no-IVUS groups (20.3% vs 18.3%; log-rank P=.67). CONCLUSION: IVUS was used for stent optimization in approximately one-third of CTO-PCIs. Despite higher lesion complexity in the IVUS group, the incidence of MACE was similar during follow-up.

BACKGROUND: Long-term outcomes of patients with prior coronary artery bypass graft (CABG) surgery undergoing chronic total occlusion (CTO) percutaneous coronary intervention (PCI) have received limited study. METHODS: We compared the clinical and angiographic characteristics and procedural and follow-up outcomes of patients with and without prior CABG in a multicenter international registry. RESULTS: Of the 1572 patients included in this analysis, a total of 498 (32%) had prior CABG. Prior CABG patients had higher J-CTO scores (2.9 ± 1.1 vs 2.2 ± 1.3; P<.001) and were less likely to undergo PCI of the left anterior descending artery (16.7% vs 29.6%; P<.001). The retrograde technique was used more often (47.4% vs 28.2%; P<.001) and was successful more often (27.4% vs 17.1%; P<.001) in the prior CABG group vs the non-prior CABG group. Technical success was lower in prior CABG patients (82.6% vs 87.9%; P<.01) with similar incidence of in-hospital major adverse cardiovascular events (3.4% vs 3%; P=.65), although in-hospital mortality was higher in the prior CABG group (2.4% vs 1.0%; P=.04). At 1-year follow-up, the composite endpoint of death, myocardial infarction, and revascularization was higher in prior CABG patients (21.79% vs 12.73%; hazard ratio, 1.76; 95% confidence interval, 1.27-2.45; P<.001). CONCLUSION: Compared with non-prior CABG patients, prior CABG patients undergoing CTO-PCI had lower technical success and higher incidence of acute and follow-up adverse cardiovascular events.

BACKGROUND: Chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has significantly evolved in recent years. METHODS: We compared the clinical, angiographic, and technical characteristics, as well as procedural outcomes of CTO-PCIs in a multicenter registry between the "early era" (2012-2016) and the "current era" (2017-2019). RESULTS: Current era patients more often had stage III or IV angina compared with early era patients (71% vs 66%, respectively; P=.03) and were less likely to undergo ad hoc CTO-PCI (13% vs 16%, respectively; P=.04). The J-CTO score was slightly lower in the current era patients vs the early era patients (2.3 ± 1.4 vs 2.5 ± 1.3, respectively; P=.04). Use of antegrade wire escalation increased in the current era (92% vs 83% in the early era patients; P<.001) whereas use of retrograde crossing decreased (29% vs 39% in the early era; P<.001) and antegrade/ dissection re-entry decreased (23% vs 32% in the early era; P<.001). Technical success rates (85% in the current era vs 86% in the early era; P=.69) and procedural success rates (83% in the current era vs 85% in the early era; P=.15) were similar, whereas the incidence of in-hospital major cardiovascular events decreased in the current era (2% vs 3% in the early era; P=.04). CONCLUSIONS: During recent years, ad hoc CTO-PCI decreased along with decreasing use of retrograde crossing and antegrade dissection and re-entry. Technical and procedural success rates remained stable, whereas the incidence of in-hospital MACE decreased.

OBJECTIVES: The aim of this study was to examine the use of saphenous vein grafts (SVGs) for retrograde crossing during chronic total occlusion (CTO) percutaneous coronary intervention (PCI). BACKGROUND: The use of SVGs for retrograde crossing during CTO PCI has received limited study. METHODS: A total of 1,615 retrograde CTO PCIs performed between 2012 and 2019 at 25 centers were examined. Clinical, angiographic, and technical characteristics and procedural outcomes were compared among retrograde cases via SVGs (SVG group) versus other collateral vessels (non-SVG group). RESULTS: Retrograde CTO PCI via SVGs was performed in 189 cases (12%). Patients in the SVG group were older (mean age 70 ± 9 years vs. 64 ± 10 years; p < 0.01) and had higher rates of prior myocardial infarction (62% vs. 51%; p < 0.01) and prior PCI (81% vs. 70%; p < 0.01). They were more likely to have moderate or severe calcification (81% vs. 65%; p < 0.01) and moderate or severe tortuosity (53% vs. 44%; p = 0.02) and had similar J-CTO (Multicenter CTO Registry in Japan) scores (3.2 ± 1.0 vs. 3.1 ± 1.1; p = 0.13) but higher PROGRESS-CTO (Prospective Global Registry for the Study of Chronic Total Occlusion Intervention) scores (4.7 ± 1.7 vs. 3.1 ± 1.1; p < 0.01). Technical (85% vs. 78%; p = 0.04) and procedural (81% vs. 74%; p = 0.04) success rates were higher in the SVG group, with no difference in in-hospital major adverse events (6.4% vs. 4.4%; p = 0.22). Contrast volume was lower in the SVG group (225 ml [173 to 325 ml] vs. 292 ml [202 to 400 ml]; p < 0.01). CONCLUSIONS: Use of SVGs for retrograde crossing is associated with higher rates of technical and procedural success and similar rates of in-hospital major adverse cardiac events compared with retrograde CTO PCI via other collateral vessels.

OBJECTIVES: The aim of this study was to investigate the incidence and impact on mortality of repeat revascularization after index percutaneous coronary intervention (PCI) or coronary artery bypass grafting (CABG) for left main coronary artery disease (LMCAD). BACKGROUND: The impact on mortality of the need of repeat revascularization following PCI or CABG in patients with unprotected LMCAD is unknown. METHODS: All patients with LMCAD and site-assessed low or intermediate SYNTAX (Synergy Between PCI With Taxus and Cardiac Surgery) scores randomized to PCI (n = 948) or CABG (n = 957) in the EXCEL (Evaluation of XIENCE Versus Coronary Artery Bypass Surgery for Effectiveness of Left Main Revascularization) trial were included. Repeat revascularization events were adjudicated by an independent clinical events committee. The effect of repeat revascularization on mortality through 3-year follow-up was examined in time-varying Cox regression models. RESULTS: During 3-year follow-up, there were 346 repeat revascularization procedures among 185 patients. PCI was associated with higher rates of any repeat revascularization (12.9% vs. 7.6%; hazard ratio: 1.73; 95% confidence interval: 1.28 to 2.33; p = 0.0003). Need for repeat revascularization was independently associated with increased risk for 3-year all-cause mortality (adjusted hazard ratio: 2.05; 95% confidence interval: 1.13 to 3.70; p = 0.02) and cardiovascular mortality (adjusted hazard ratio: 4.22; 95% confidence interval: 2.10 to 8.48; p < 0.0001) consistently after both PCI and CABG (pint = 0.85 for both endpoints). Although target vessel revascularization and target lesion revascularization were both associated with an increased risk for mortality, target vessel non-target lesion revascularization and non-target vessel revascularization were not. CONCLUSIONS: In the EXCEL trial, repeat revascularization during follow-up was performed less frequently after CABG than PCI and was associated with increased mortality after both procedures. Reducing the need for repeat revascularization may further improve long-term survival after percutaneous or surgical treatment of LMCAD. (EXCEL Clinical Trial; NCT01205776).

AIMS: Limited data exist regarding procedural and clinical outcomes of percutaneous coronary intervention (PCI) in patients with trifurcation disease of the distal left main (LM) coronary artery. We therefore aimed to examine the procedural methods and early and late outcomes among patients undergoing distal LM trifurcation versus bifurcation PCI in the EXCEL trial. METHODS AND RESULTS: Patients with distal LM bifurcation disease randomised to PCI with everolimus-eluting stents in the EXCEL trial were categorised into those with and without trifurcation involvement. Angiographic and procedural characteristics in addition to clinical events up to five-year follow-up after PCI were compared. Among 605 patients with site-reported distal LM disease, 61 patients (10.1%) were identified with trifurcation anatomy. The five-year primary composite endpoint of death, myocardial infarction, or stroke occurred in 16.6% of patients with trifurcation disease compared with 22.5% of patients with distal bifurcation disease only (p=0.32). Ischaemia-driven target lesion revascularisation rates were also similar (11.9% vs 12.0%, p=0.94). No significant differences in definite or probable stent thrombosis were observed between treatment groups (1.7% vs 2.3%, p=0.76). CONCLUSIONS: Despite the greater inherent complexity, procedural and long-term clinical outcomes following PCI of distal LM trifurcations with everolimus-eluting stents in a modest-sized cohort from the EXCEL trial were similar compared with treatment of distal LM bifurcation disease without trifurcations. These findings support PCI as a treatment strategy for selected patients with distal LM trifurcation disease. ClinicalTrials.gov Identifier: NCT01205776.

The impact of peripheral artery disease (PAD) in patients undergoing chronic total occlusion (CTO) percutaneous coronary intervention (PCI) has received limited study. We reviewed 3999 CTO PCIs performed in 3914 patients between 2012 and 2018 at 25 centers, 14% of whom had a history of PAD. We compared the clinical and angiographic characteristics and procedural outcomes of patients with versus without history of PAD. Patients with PAD were older (67 ± 9 vs 64 ± 10 years, P < .001) and had a higher prevalence of cardiovascular risk factors. They also had more complex lesions as illustrated by higher Japanese CTO score (2.7 ± 1.2 vs 2.4 ± 1.3, P < .001). In patients with PAD, the final crossing technique was less often antegrade wire escalation (40% vs 51%, P < .001) and more often the retrograde approach (23 vs 20%, P < .001) and antegrade dissection/reentry (20% vs 16%, P < .001). Technical success was similar between the 2 study groups (84% vs 87%, P = .127), but procedural success was lower for patients with PAD (81% vs 85%, P = .015). The incidence of in-hospital major adverse cardiac events was higher among patients with PAD (3% vs 2%, P = .046). In conclusion, patients with PAD undergoing CTO PCI have more comorbidities, more complex lesions, and lower procedural success.

BACKGROUND: During chronic total occlusion (CTO) percutaneous coronary intervention (PCI), sometimes non-CTO lesions are also treated. METHODS: We compared the clinical and procedural characteristics and outcomes of CTO PCIs with and without concomitant treatment of a non-CTO lesion in a contemporary multicenter CTO registry. RESULTS: Of the 3598 CTO PCIs performed at 21 centers between 2012 and 2018, 814 (23%) also included PCI of at least one non-CTO lesion. Patients in whom non-CTO lesions were treated were older (65⯱â¯10 vs. 64⯱â¯10â¯years, pâ¯=â¯0.03), more likely to present with an acute coronary syndrome (32% vs. 23%, pâ¯<â¯0.01), and less likely to undergo PCI of a right coronary artery (RCA) CTO (46% vs. 58%, pâ¯<â¯0.01). The most common non-CTO lesion location was the left anterior descending artery (31%), followed by the circumflex (29%) and the RCA (25%).Combined non-CTO and CTO-PCI procedures had similar technical (88% vs. 87%, pâ¯=â¯0.33) and procedural (85% vs. 85%, pâ¯=â¯0.74) success and major in-hospital complication rates (3.4% vs. 2.7%, pâ¯=â¯0.23), but had longer procedure duration (131 [88, 201] vs. 117 [75, 179] minutes, pâ¯<â¯0.01), higher patient air kerma radiation dose (3.0 [1.9, 4.8] vs. 2.8 [1.5, 4.6] Gray, pâ¯<â¯0.01) and larger contrast volume (300 [220, 380] vs. 250 [180, 350] ml, pâ¯<â¯0.01). CONCLUSIONS: Combined CTO PCI with PCI of non-CTO lesions is associated with similar success and major in-hospital complication rates compared with cases in which only CTOs were treated, but requires longer procedure duration and higher radiation dose and contrast volume.

BACKGROUND: Limited research has detailed the outcomes of chronic total occlusion (CTO) percutaneous coronary intervention (PCI) with independent core laboratory and event adjudication. This study examined procedural, clinical, and patient-reported health status outcomes among patients undergoing CTO PCI with specific focus on outcomes for those treated with zotarolimus-eluting stents (ZES). METHODS: Among 500 consecutive patients undergoing attempted CTO PCI, procedural and in-hospital clinical outcomes were examined in addition to the 1-year composite endpoint of death, myocardial infarction, and target lesion revascularization (major adverse cardiac events, MACE). In a pre-specified cohort of 250 patients, health status measures were ascertained at baseline and 1 year. A powered secondary endpoint was 1-year MACE among patients treated with ZES compared with a performance goal. RESULTS: Demographic, lesion, and procedural characteristics for the overall population included prior bypass surgery, 29.8%; diabetes, 35.2%; occlusion length >20 mm, 71.3%; J-CTO score, 2.5 ± 1.1; and primary retrograde strategy, 30.8%. Overall guidewire crossing was 90.9%; clinical success following guidewire crossing, 94.3%; and 1-year MACE rate, 12.1%. One-year health status significantly improved from baseline with successful CTO-PCI (angina frequency, 72.7 ± 26.5 at baseline to 96.0 ± 10.8, p < .0001). Compared with a performance goal derived from prior CTO DES trials (1-year hierarchal MACE, 25.2%), treatment with ZES was associated with significantly lower MACE (18.2%, one-sided upper CI, 23.6%, p = .017). CONCLUSIONS: Favorable procedural success, health status improvements and late-term clinical outcomes inform the relative risks and benefits of CTO PCI when performed in a clinically indicated, complex patient population representative of those treated in clinical practice.
