Transcatheter aortic-valve replacement with a self-expanding prosthesis.
BACKGROUND We compared transcatheter aortic-valve replacement (TAVR), using a self-expanding transcatheter aortic-valve bioprosthesis, with surgical aortic-valve replacement in patients with severe aortic stenosis and an increased risk of death during surgery. METHODS We recruited patients with severe aortic stenosis who were at increased surgical risk as determined by the heart team at each ...
متن کاملPercutaneous Implantation of the CoreValve Self-Expanding Valve Prosthesis in High-Risk Patients With Aortic Valve Disease
Background—The morbidity and mortality of surgical aortic valve replacement are increased in elderly patients with multiple high-risk comorbid conditions. Therefore, a prospective, single-center, nonrandomized study was performed in high-risk patients with aortic valve disease to evaluate the feasibility and safety of percutaneous implantation of a novel self-expanding aortic valve bioprosthesi...
متن کاملPercutaneous implantation of the CoreValve self-expanding aortic valve prosthesis in patients with severe aortic stenosis: early experience in Spain.
INTRODUCTION AND OBJECTIVES The aim of the study was to describe early experience and medium-term follow-up with the CoreValve self-expanding aortic prosthesis at three Spanish hospitals. METHODS The study included patients with severe symptomatic aortic stenosis. Other inclusion criteria were: aortic valve area <1 cm(2) (<0.6 cm(2)/m(2)); aortic valve annulus diameter in the range 20-27 mm; ...
متن کاملCost-Effectiveness of Transcatheter Aortic Valve Replacement With a Self-Expanding Prosthesis Versus Surgical Aortic Valve Replacement.
BACKGROUND Previous studies of the cost-effectiveness of transcatheter aortic valve replacement (TAVR) have been based primarily on a single balloon-expandable system. OBJECTIVES The goal of this study was to evaluate the cost-effectiveness of TAVR with a self-expanding prosthesis compared with surgical aortic valve replacement (SAVR) for patients with severe aortic stenosis and high surgical...
متن کاملPercutaneous transcatheter implantation of an aortic valve prosthesis for calcific aortic stenosis: first human case description.
BACKGROUND The design of a percutaneous implantable prosthetic heart valve has become an important area for investigation. A percutaneously implanted heart valve (PHV) composed of 3 bovine pericardial leaflets mounted within a balloon-expandable stent was developed. After ex vivo testing and animal implantation studies, the first human implantation was performed in a 57-year-old man with calcif...
