Background: The safety of drug-eluting stents (DES) vs. bare metal stents (BMS) in the perioperative setting, a heightened state of inflammation and thrombosis is not well defined.
Objectives: To characterize the treatment of complex bifurcation lesions (BL) with the Tryton Bifurcation Stent (TBS) paired with an everolimus-eluting stent (EES).
Objectives: We evaluated whether morphological characteristics of neointimal tissue of in-stent restenosis (ISR) lesions assessed by optical coherence tomography (OCT) affect periprocedural elevation of creatine kinase-myocardial band (CK-MB).
Objectives: This study aimed to compare the effect of bivalirudin and unfractionated heparin (UFH) on residual thrombus burden assessed by frequency-domain optical coherence tomography (FD-OCT), and on angiographic indices of microvascular obstruction (MVO).
Objective: To determine the impact of ostial guiding catheter disengagement during measurement of fractional flow reserve (FFR) in patients with an isolated proximal left anterior descending artery (LAD) stenosis
Objectives: This article sought to describe a new modification of the Melody valve that allows percutaneous pulmonary valve implantation (PPVI) in complex outflow tracts.
Objective: This study aimed to report the outcomes of African Americans (AAs) in the US undergoing transcatheter aortic valve replacement (TAVR) for severe aortic stenosis (AS).
Objectives: We present a case series of five patients in whom percutaneous paravalvular leak closure with the AVP4 device has been undertaken for symptomatic aortic regurgitation after CoreValve TAVI.
Objectives: Significant tricuspid regurgitation (TR) is a marker for late-stage myocardial and valvular heart disease. Whether preoperative TR affects clinical outcomes of patients undergoing transcatheter aortic valve replacement (TAVR) has never been investigated. This study sought to identify the impact of moderate and severe TR on outcomes after TAVR.
Objectives: We performed systematic optical coherence tomography (OCT) analyses after bioresorbable vascular scaffolds (BVS) implantation in a “real world” setting aiming at evaluating scaffold expansion and longitudinal integrity.
Background: While the current methodology for determining fibrous cap (FC) thickness of lipid plaques is based on manual measurements of arbitrary points, which could lead to high variability and decreased accuracy, it ignores the three-dimensional (3-D) morphology of coronary artery disease.
Background: Patients with diabetes mellitus (DM) remain at high risk for stent restenosis and adverse cardiovascular events in the drug-eluting stent era. The amphilimus-eluting stent (AES) is a third generation reservoir-based polymer-free drug-eluting stent that has shown promising preliminary results in patients with DM. It has been suggested that the formulation of the drug with fatty acids could not only modulate the drug release in a timely manner but also achieve convenient levels of drug concentration in diabetic cardiac cells. The aim of this trial is to assess the efficacy of the AES in patients with DM compared with the cobalt chromium everolimus-eluting stent with non-erodible polymer (EES).
Objectives: We investigated the temporal patterns of drug-eluting stents (DES) failure and its relationship with clinical outcomes in patients with DES failure.
Background: Up to 40% of ischaemic strokes are cryptogenic. A strong association between cryptogenic stroke and the prevalence of patent foramen ovale (PFO) suggests paradoxical embolism via PFO as a potential cause. Randomized trials failed to demonstrate superiority of PFO closure over medical therapy.
Background: Drug-eluting stents (DES) have largely replaced bare-metal stents (BMS) for percutaneous coronary intervention (PCI). It is uncertain, however, whether introduction of DES had a significant impact on the comparative effectiveness of PCI versus coronary artery bypass graft surgery (CABG) for death and myocardial infarction (MI).
