Perkinsus marinus infection intensity was measured in eastern oysters Crassostrea virginica collected in October and December 1993, and March, May, and July 1994 from 3 U.S. sites: Apalachicola Bay (FL), Chesapeake Bay (VA), and Oyster Bay (NY). Gill, mantle, digestive gland, adductor muscle, hemolymph, and remaining tissue (including gonadal material and(More)
BACKGROUND Patients with coronary total occlusions are at especially high risk for restenosis and new revascularizations. Sirolimus-eluting stents dramatically improved the clinical outcome of this subset of patients in randomized trials, but other drug-eluting stents, mainly the everolimus-eluting stent (currently the most frequently used stent), have not(More)
The no-reflow phenomenon (NRP) is characterized by an inadequate myocardial tissue perfusion in the presence of a patent epicardial coronary artery. It generally occurs after temporary occlusion of the artery causing myocardial ischemia and necrosis that persist after relief of the vessel occlusion, without evidence of epicardial mechanical obstruction.(More)
AIMS Data on primary percutaneous coronary intervention for ST-segment elevation in nonagenarian patients are very limited. Our aim was to evaluate the results of primary percutaneous coronary intervention in patients ≥ 90 years old with ST-segment elevation acute myocardial infarction. METHODS AND RESULTS We conducted a multicentre registry focused on(More)
BACKGROUND In order to improve technique and to prevent serious procedural complications during transcatheter aortic valve implantation (TAVI), it is crucial to identify the causes of death of patients undergoing this procedure. OBJECTIVE The objective of this study was to identify the causes of death during the procedure and at 1 month in patients with(More)
The only clinical benefit of drug-eluting stents (DESs) over bare metal stents (BMSs) is a significant decrease in the need for new revascularization procedures. We evaluated whether DESs also decrease the incidence of myocardial infarction at midterm. We performed a meta-analysis from 25 randomized trials comparing commercially available DESs with BMSs(More)
INTRODUCTION AND OBJECTIVES Percutaneous closure of paravalvular leakage is an alternative to surgery in high-risk patients, but its use has been limited by a lack of specific devices. More appropriate devices-like the Amplatzer Vascular Plug III-have recently been developed, but information about their efficacy and safety is still scarce. The objective of(More)
Restenosis is an important limitation of percutaneous coronary interventions (PCI). In-stent restenosis is mainly due to neointimal hyperplasia, a proliferative process modulated by inflammatory mechanisms. Numerous technical and pharmacological means have been tested to reduce restenosis rates, with frequently disappointing clinical results. Drug-eluting(More)
INTRODUCTION AND OBJECTIVES Malignant pericardial effusion has a high recurrence rate after pericardiocentesis. We sought to confirm the efficacy of percutaneous balloon pericardiotomy as the initial treatment of choice for these effusions. METHODS Retrospective analysis of the clinical, echocardiographic, and follow-up characteristics of a consecutive(More)
