Valve replacement surgery is the replacement of one or more of the heart valves with either an artificial heart valve or a bioprosthesis (homograft from human tissue or xenograft e.g. from pig). It is an alternative to valve repair .
Introduced in 2001, the Piaggio Beverly has been produced in engine sizes ranging from 125 to 500 cc. Early models were powered by Piaggio's water-cooled L.E.A.D.E.R. engine. In 2005 models with 250 cm 3 and 500 cm 3 displacement were also presented and the engine range was subsequently expanded to 300 cm 3, 350 cm 3 and 400 cm 3 displacement.
The valve is excised 4–5 mm from the annulus, leaving intact the attached chordae unless they are calcified or otherwise diseased. The valve is replaced by a mechanical or bioprosthetic valve. The replacement valve is sewn into the annulus with interrupted or horizontal mattress sutures with the pledgets on the atrial side. [20]
Minimally invasive cardiac surgery, encompasses various aspects of cardiac surgical procedures (aortic valve replacement, mitral valve repair, coronary artery bypass surgery, ascending aorta or aortic root surgery) that can be performed with minimally invasive approach either via mini-thoracotomy or mini-sternotomy.
Aortic valve repair is a surgical procedure used to correct some aortic valve disorders as an alternative to aortic valve replacement. [2] Aortic valve repair is performed less often and is more technically difficult than mitral valve repair. There are two surgical techniques of aortic-valve repair: The Reimplantation-Technique (David-Procedure ...
Cardiac surgery, or cardiovascular surgery, is a surgery on the heart or great vessels performed by cardiac surgeons.It is often used to treat complications of ischemic heart disease (for example, with coronary artery bypass grafting); to correct congenital heart disease; or to treat valvular heart disease from various causes, including endocarditis, rheumatic heart disease, [1] and ...
Transcatheter aortic valve replacement (TAVR) is the implantation of the aortic valve of the heart through the blood vessels without actual removal of the native valve (as opposed to the aortic valve replacement by open heart surgery, surgical aortic valve replacement, AVR).
Transcatheter pulmonary valve replacement (TPVR), also known as percutaneous pulmonary valve implantation (PPVI), is the replacement of the pulmonary valve via catheterization through a vein. It is a significantly less invasive procedure in comparison to open heart surgery and is commonly used to treat conditions such as pulmonary atresia .
