Background: In diabetic patients with multivessel coronary artery disease, coronary artery bypass grafting (CABG) has shown long-term benefits over percutaneous coronary intervention (PCI). Physiology-guided PCI has shown to improve clinical outcomes in multivessel coronary artery disease, though its impact in diabetic patients has never been investigated. We evaluated long-term clinical outcomes of diabetic patients with multivessel coronary artery disease treated with fractional flow reserve (FFR)–guided PCI compared with CABG.
Background: Hybrid coronary revascularization (HCR) treats multivessel coronary artery disease by combining a minimally invasive surgical approach to the left anterior descending artery with percutaneous coronary intervention for non–left anterior descending diseased coronary arteries. The objective of this study is to compare HCR and conventional coronary artery bypass graft (CABG) surgery medium-term outcomes.
Background: The potential impact of quantitative flow ratio (QFR) based functional Synergy Between Percutaneous Coronary Intervention With Taxus and Cardiac Surgery (SYNTAX) score (FSSQFR) on prognostication and revascularization strategy choice has not been fully investigated, and the discriminant ability of FSSQFR needs further validation.
Background: Subclinical atherothrombosis and plaque healing may lead to rapid plaque progression. The histopathologic healed plaque has a layered appearance when imaged using optical coherence tomography. We assessed the frequency, predictors, distribution, and morphological characteristics of optical coherence tomography layered culprit and nonculprit plaques in patients with acute myocardial infarction.
Background: There is conflicting data regarding transcatheter aortic valve replacement in patients with paradoxical low-flow, low-gradient aortic stenosis (pLFLG-AS). The authors aimed to examine the hemodynamic and clinical benefit of transcatheter aortic valve replacement in symptomatic patients with pLFLG-AS compared with high-gradient severe AS.
Background: Specific algorithms for use of optical coherence tomography (OCT) to guide percutaneous coronary intervention (PCI) are scarce. Also, the relative benefits of intravascular imaging guidance have not been tested against an optimized angiography-guided PCI strategy. In iSIGHT (Optical Coherence Tomography Versus Intravascular Ultrasound and Angiography to Guide Percutaneous Coronary Interventions), we aimed to investigate whether OCT-guided PCI achieves noninferior stent expansion compared with intravascular ultrasound (IVUS) guidance and if both imaging modalities lead to superior stent expansion compared with an optimized angiography-based strategy.
Background: Fractional flow reserve (FFR)-guided treatment has been demonstrated to improve percutaneous coronary intervention (PCI) results. However, little is known on the long-term impact of low post-PCI FFR.
Background: Prolonged dual antiplatelet therapy (DAPT) after percutaneous coronary intervention is associated with increased bleeding, despite a reduced incidence of ischemic events. The SYNERGY everolimus-eluting stent is a thin-strut platinum-chromium stent that elutes everolimus from a thin abluminal layer of bioabsorbable polymer. These design elements may facilitate rapid endothelialization and enable shorter-duration DAPT.
Background: Uncertainty exists over whether stents commonly used for percutaneous coronary intervention have comparable short- and long-term safety. The objective of this study was to determine the outcomes of patients treated with bioabsorbable polymer everolimus-eluting (BP-EES; Synergy, Boston Scientific), durable polymer everolimus-eluting (DP-EES; XIENCE, Abbott Vascular), or durable polymer zotarolimus-eluting (DP-ZES; Resolute, Medtronic) stents in routine clinical practice.
Background: Percutaneous intervention of calcified coronary lesions often requires lesion preparation with either balloon dilatation or atherectomy. We sought to evaluate the impact of lesion preparation strategy on stent expansion following preparation of severely calcified coronary lesions with modified (cutting/scoring) balloons (MB) versus rotational atherectomy (RA) and to evaluate the impact of calcium burden as assessed by optical coherence tomography (OCT) on acute stent performance.
Background: Ductal-dependent cyanotic newborns require a secure source of pulmonary blood flow. There has been a recent migration to selective ductal (patent ductus arteriosus [PDA]) stenting for some of these children. Universal (nonselective) ductal stenting for all infants with ductal-dependent pulmonary blood flow is controversial. We examine outcomes from a single center with this practice change.
Background: Transradial access (TRA) has emerged as the preferred vascular access site for coronary angiography and percutaneous coronary intervention. This systematic review and meta-analysis was performed to evaluate 30-day all-cause mortality comparing TRA with transfemoral access for percutaneous coronary intervention in patients with ST-segment–elevation myocardial infarction.
Background: Despite the rapid adoption of transcatheter aortic valve replacement (TAVR) since its initial approval in 2011, the frequency and outcomes of surgical explantation of TAVR devices (TAVR-explant) is poorly understood.
Background: Optimal antithrombotic management of patients with preexisting atrial fibrillation undergoing transcatheter aortic valve replacement is challenging given the need to balance the risk of bleeding and thromboembolism. We aimed to examine variation in care and association of antithrombotic therapies with 1-year outcomes of stroke, bleeding, and mortality in patients undergoing transcatheter aortic valve replacement with concomitant atrial fibrillation in the United States.
Background: Atrial fibrillation (AF), mitral regurgitation (MR), and left ventricular (LV) ejection fraction have a complex interplay. We evaluated the role of AF in patients with heart failure and moderate-to-severe or severe secondary MR enrolled in the randomized COAPT trial (Cardiovascular Outcomes Assessment of the MitraClip Percutaneous Therapy for Heart Failure Patients With Functional Mitral Regurgitation) and its impact on mechanisms and outcomes with the MitraClip.
