Background: Platelet inhibition after percutaneous coronary intervention (PCI) reduces the risk of myocardial infarction (MI) but increases the risk of bleeding. MIs and bleeds during the index hospitalization for PCI are known to negatively affect long-term outcomes. The impact of spontaneous bleeding occurring after discharge on long-term mortality is unknown.
Background: Patients receiving oral anticoagulation (OAC) who undergo drug-eluting stent (DES) implantation require additional dual antiplatelet therapy with aspirin and clopidogrel. Such triple therapy confers an elevated bleeding risk, and its optimal duration is not known.
Background: More than 20% of patients presenting to the cardiac catheterization laboratory with angina have no angiographic evidence of coronary artery disease. Despite a “normal” angiogram, these patients often have persistent symptoms, recurrent hospitalizations, a poor functional status, and adverse cardiovascular outcomes, without a clear diagnosis.
Background: We assessed trends in the performance of transcatheter aortic valve implantation in the United Kingdom from the first case in 2007 to the end of 2012. We analyzed changes in case mix, complications, outcomes to 6 years, and predictors of mortality.
Background: There is a paucity of data on the use of optimal medical therapy (OMT) in patients with complex coronary artery disease undergoing revascularization with percutaneous coronary intervention or coronary artery bypass grafting (CABG) and its long-term prognostic significance.
Background: We aimed to determine the incidence, predictors, clinical characteristics, management, and outcomes of infective endocarditis (IE) after transcatheter aortic valve implantation (TAVI).
Background: The Coarctation of the Aorta Stent Trial (COAST) was designed to assess the safety and efficacy of the Cheatham Platinum stent when used in children and adults with native or recurrent coarctation. Acute outcomes have been reported. We report here follow-up to 2 years.
Objectives: The aim of this study was to develop a new model for assessment of stenosis severity in a bifurcation lesion including its core. The diagnostic performance of this model, powered by 3-dimensional quantitative coronary angiography to predict the functional significance of obstructive bifurcation stenoses, was evaluated using fractional flow reserve (FFR) as the reference standard.
Objectives: This study sought to evaluate the optimal percutaneous coronary intervention techniques using drug-eluting stents for bifurcation coronary lesions.
Objectives: This study sought to compare the outcomes of fractional flow reserve (FFR)–guided and angiography (Angio)–guided provisional side-branch (SB) stenting for true coronary bifurcation lesions.
Objectives: The aim of this study was to assess adenosine infusion via a cannula in the back of the hand compared with central venous access to achieve peak hyperemia during fractional flow reserve (FFR).
Objectives: The aim of this study was to analyze the change of upper limb function when percutaneous coronary procedures were performed through the radial artery.
Objectives: The purpose of this study was to determine the efficacy and safety of radial versus femoral access in women undergoing coronary angiography/intervention.
Objectives: This study sought to assess the geometric interaction between the Lotus Valve System transcatheter aortic prosthesis (Boston Scientific, Natick, Massachusetts) and the native aortoventricular interface using multidetector computed tomography (MDCT).
Objectives: This paper reviews the published data and reports 3 cases of thrombosis involving CoreValve (Medtronic, Minneapolis, Minnesota) and 1 involving Edward Sapien (Edwards Lifesciences, Irvine, California) devices. Three of these cases had pathological findings at autopsy.
