OBJECTIVES The study sought to examine the risk of ischemic events and bleeding episodes associated with differing antithrombotic strategies in patients undergoing transcatheter aortic valve replacement (TAVR) with concomitant atrial fibrillation (AF). BACKGROUND Guidelines recommend antiplatelet therapy (APT) post-TAVR to reduce the risk of stroke.(More)
There are currently no data evaluating the hematologic and biocompatibility profile of transcatheter aortic valves in vivo. We evaluated the incidence, predictive factors, and clinical consequences associated with hemolysis post-transcatheter aortic valve implantation (TAVI). A total of 122 patients who underwent TAVI with a balloon-expandable valve were(More)
BACKGROUND There are scarce data available on transcatheter mitral valve replacement (TMVR), and these have been limited to procedural results, with no follow-up status reported. OBJECTIVES The goal of this study was to evaluate the feasibility, procedural results, and 6-month follow-up outcomes after TMVR with a mitral transcatheter heart valve (Fortis,(More)
BACKGROUND Transcatheter mitral valve implantation (TMVI) for severely calcified native mitral valve disease recently emerged as a treatment option in patients deemed inoperable by conventional techniques. Yet no systematic appraisal currently exists characterizing this novel treatment paradigm. METHODS A systematic literature review summarizing the(More)
Native valve infective endocarditis (IE) in patients with normal valves has increased in the last decades. Whether patients with normal valves present a similar prognosis to those with pathologic valves is unresolved. Our aim is to describe epidemiologic and clinical differences between patients with left-sided IE and normal valves and those with native(More)
RATIONALE Refractory angina constitutes a clinical problem. OBJECTIVE The aim of this study was to assess the safety and the feasibility of transendocardial injection of CD133(+) cells to foster angiogenesis in patients with refractory angina. METHODS AND RESULTS In this randomized, double-blinded, multicenter controlled trial, eligible patients were(More)
BACKGROUND Scarce data exist on the incidence of and factors associated with valve hemodynamic deterioration (VHD) after transcatheter aortic valve replacement (TAVR). OBJECTIVES This study sought to determine the incidence, timing, and predictors of VHD in a large cohort of patients undergoing TAVR. METHODS This multicenter registry included 1,521(More)
INTRODUCTION AND OBJECTIVES Despite the rapid global uptake of transcatheter aortic valve implantation, valve trombosis has yet to be systematically evaluated in this field. The aim of this study was to determine the clinical characteristics, diagnostic criteria, and treatment outcomes of patients diagnosed with valve thrombosis following transcatheter(More)
A 72-year-old woman with diabetes mellitus and end-stage ischemic heart disease was admitted to the hospital because of an episode of unstable angina. She had undergone coronary artery bypass graft surgery 4 years earlier with sequential left internal mammary artery to left anterior descending and diagonal artery, and saphenous vein graft to left marginal(More)
