Transcatheter Aortic Valve Insertion – TAVI – is a technique involving the implantation of an artificial valve into a narrowed aortic valve without the need to stop the heart. There are two variants of this procedure. In the first, the artificial valve is...
Transcatheter aortic valve implantation (TAVI), also referred to as transcatheter aortic valve replacement (TAVR), is the deployment of a bioprosthesis in the aortic valve using a catheter. In contrast to traditional open-heart surgery (i.e. surgical aortic valve...
Transcatheter aortic valve implantation (TAVI) has become an alternative to surgical aortic valve replacement (sAVR) for patients at high risk for surgery. The objective of this analysis is to evaluate the safety, effectiveness, and cost-effectiveness...
The aortic valve is one of four valves in the heart. It allows blood to flow from the left ventricle of the heart into the aorta (the main artery in the body). Aortic valve stenosis occurs if the valve narrows and cannot open all the way, partially blocking the...
Aortic valvular stenosis, or narrowing of the valve orifice, is a progressive disease that generally affects patients over the age of 65 years in Western countries and is usually caused by degenerative calcification. Aortic stenosis causes increasing resistance...
Research Questions: What is the clinical effectiveness and safety of the Perceval S sutureless valve for patients requiring aortic valve replacement? What is the cost-effectiveness of the Perceval S sutureless valve for patients requiring aortic valve replacement? Key...
Abstract Background Surgical aortic valve replacement (SAVR) is the conventional treatment in patients at low or intermediate surgical risk. Transcatheter aortic valve implantation (TAVI) is a less invasive procedure, originally developed as an alternative for...
