OBJECTIVES: To study the long-term outcomes of rotational atherectomy (RA) for chronic total occlusion (CTO) percutaneous coronary intervention (PCI). BACKGROUND: There is little evidence on the incidence, procedural results and long-term outcomes of RA for CTO PCI. METHODS: This registry included data from consecutive patients undergoing CTO PCI at four specialized centers. Major adverse cardiac events (MACE: cardiac death, target-vessel myocardial infarction and ischemia-driven target-vessel revascularization) on follow-up were the primary endpoint...

BACKGROUND: There are few data regarding the procedural and follow-up outcomes of different antegrade dissection/re-entry (ADR) techniques for chronic total occlusion (CTO) percutaneous coronary intervention (PCI). METHODS: We compiled a multicenter registry of consecutive patients undergoing ADR-based CTO PCI at four high-volume specialized institutions. Patients were divided according to the specific ADR technique used: subintimal tracking and re-entry (STAR), limited antegrade subintimal tracking (LAST), or device-based with the CrossBoss/Stingray system (Boston Scientific, Marlborough, MA)...

AIMS: Septal surfing and distal tip injections are two techniques used for septal crossing in retrograde chronic total occlusion (CTO) percutaneous coronary interventions (PCI). We examined for the first time the safety and feasibility of the septal surfing technique. METHODS AND RESULTS: Among 470 consecutive CTO PCIs performed between 01/2010 and 12/2015, 240 (51%) involved a retrograde attempt. In the septal crossing subgroup, we evaluated if the Werner collateral channel (CC) classification, CTO location, tortuosity, and number of large septal CCs influenced retrograde crossing success, time, perforation...

The experience with the transradial approach in percutaneous coronary intervention (PCI) of chronic total occlusions (CTOs) in the United States is limited. We looked at the safety and feasibility of a home-made sheathless transradial technique (STT) with regular 8Fr catheters in CTO PCI. In March 2013, we developed an 8Fr STT for CTO PCI. We compared 119 patients who had the STT versus 122 treated with a standard transradial or transfemoral approach. The primary outcomes of interest were major vascular or bleeding site access complications...

BACKGROUND: The prevalence of native coronary chronic total occlusions (CTOs) after coronary artery bypass grafts (CABGs) is higher than in non-CABG population. We examined outcomes of CTO percutaneous coronary intervention (PCI) post-CABG versus without CABG. Then, we looked at feasibility and outcomes of retrograde CTO PCI via patent or occluded saphenous vein graft. METHODS AND RESULTS: We compared patient and procedural characteristics of 470 CTO cases treated from January 2010 to December 2015 depending on history of CABG...

BACKGROUND: Hospitals treating patients with ST-elevation myocardial infarction (STEMI) may show good results with reperfusion treatment (fibrinolysis or primary percutaneous coronary intervention [PPCI]), but a comprehensive evaluation should factor in outcomes of patients with STEMI who do not receive reperfusion. We compared outcomes of patients receiving and not receiving reperfusion within a complete system of STEMI care by hospital type: PPCI centres, fibrinolysis centres, centres that only transfer for PPCI, and centres providing a mix of fibrinolysis and PPCI transfer...

The entry to the subadventitial space is not a mode of failure, but the road to success in many chronic total occlusion (CTO) percutaneous coronary intervention (PCI) cases. Long-term clinical outcomes of subadventitial stenting are favorable and similar to intraluminal stenting. However, the subadventitial space histology and physiology remains different to the coronary true intraluminal space. We report a complication specific to stenting of the subadventitial space, where overlapping stents dislocated from one another, which resulted in late non-occlusive stent thrombosis...

Dual antiplatelet therapy (DAPT) with clopidogrel and aspirin is used for the prevention of cardiovascular events following percutaneous coronary intervention (PCI). These agents increase the risk of gastrointestinal bleeding. To prevent these events, proton pump inhibitors (PPI) are routinely prescribed. It has been reported that with the exception of pantoprazole and dexlanzoprazole, PPIs can impede conversion of clopidogrel by cytochrome P450 2C19 (CYP2C19) to its active metabolite, a critical step required for clopidogrel efficacy...

Patients with ST-elevation myocardial infarction (STEMI) who die in hospital before inpatient admission are generally not included in clinical studies and registries, and the clinical profiles of patients who die earlier versus later are not well defined. We aimed to characterize all patients with STEMI who arrived at emergency departments in the province of Quebec (Canada) based on inpatient admission status and when they died. All patients who presented with symptoms and core laboratory-confirmed STEMI or left bundle branch block during 6 months in 82 hospitals in Quebec were included...

The "hybrid" approach to chronic total occlusion (CTO) percutaneous coronary intervention (PCI) was developed to provide guidance on optimal crossing strategy selection. Dual angiography remains the cornerstone of clinical decision making in CTO PCI. Four angiographic parameters are assessed: (a) morphology of the proximal cap (clear-cut or ambiguous); (b) occlusion length; (c) distal vessel size and presence of bifurcations beyond the distal cap; and (d) location and suitability of location and suitability of a retrograde conduit (collateral channels or bypass grafts) for retrograde access...

Coronary chronic total occlusions (CTOs) are commonly encountered in patients undergoing coronary angiography. Several observational studies have demonstrated that successful CTO revascularization is associated with better cardiovascular outcomes and enhanced quality of life (QOL). However, in the absence of randomized trials, its prognostic benefit for patients remains debated. Over the past decade, the interest of the interventional community in CTO percutaneous coronary intervention (PCI) has exponentially grown due to important developments in dedicated equipment and techniques, resulting in high success and low complication rates...

When dealing with flush ostial chronic total occlusion (CTO) and no viable retrograde option, the only way to perform recanalization is through an antegrade approach. Such a procedure can be extremely difficult considering the ambiguity of the proximal cap. We demonstrate how we solved ambiguity of the proximal cap of an ostial obtuse marginal CTO with the help of cardiac multidetector computed tomography (MDCT). We also discuss several techniques including bilateral radial approach with home-made sheathless large-bore catheters, IVUS-guided cap puncture, ping-pong guide catheters engagement in the left main, and bioresorbable vascular scaffold (BVS) for an ostial left circumflex disease that we all used in our CTO case...

Successful percutaneous coronary intervention (PCI) for chronic total occlusions (CTOs) has been associated with clinical benefit. There are no randomized controlled trials on long-term clinical outcomes after CTO PCI, limiting the available evidence to observational cohort studies. We sought to perform a weighted meta-analysis of the long-term outcomes of successful versus failed CTO PCI. A total of 25 studies, published from 1990 to 2014, with 28,486 patients (29,315 CTO PCI procedures) were included. We analyzed data on mortality, subsequent coronary artery bypass grafting (CABG), myocardial infarction, major adverse cardiac events, angina pectoris, stroke, and target vessel revascularization using random-effects models...

BACKGROUND: We conducted a systematic review to examine the efficacy of the Atkins, South Beach, Weight Watchers (WW), and Zone diets, with a particular focus on sustained weight loss at ≥12 months. METHODS AND RESULTS: We systematically searched MEDLINE, EMBASE, and the Cochrane Library of Clinical Trials to identify randomized controlled trials (RCTs) published in English with follow-up ≥4 weeks that examined the effects of these 4 popular diets on weight loss and cardiovascular risk factors...
