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 .
Aortic valve replacement is a procedure whereby the failing aortic valve of a patient's heart is replaced with an artificial heart valve. The aortic valve may need to be replaced because: The valve is leaky ( aortic insufficiency, also known as aortic regurgitation) The valve is narrowed and doesn't open fully ( aortic stenosis)
Transcatheter aortic valve implantation ( TAVI) 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). The first TAVI was performed on 16 April 2002 by Alain Cribier ...
See media help. Valvular heart disease is any cardiovascular disease process involving one or more of the four valves of the heart (the aortic and mitral valves on the left side of heart and the pulmonic and tricuspid valves on the right side of heart). These conditions occur largely as a consequence of aging, [1] but may also be the result of ...
The Ross procedure, also known as pulmonary autograft, is a heart valve replacement operation to treat severe aortic valve disease, such as in children and young adults with a bicuspid aortic valve. [1] It involves removing the diseased aortic valve, situated at the exit of the left side of the heart (where the aorta begins), and replacing it ...
Bentall procedure. The Bentall procedure is a type of cardiac surgery involving composite graft replacement of the aortic valve, aortic root, and ascending aorta, with re-implantation of the coronary arteries into the graft. This operation is used to treat combined disease of the aortic valve and ascending aorta, including lesions associated ...
Artificial heart valve. An artificial heart valve is a one-way valve implanted into a person's heart to replace a heart valve that is not functioning properly ( valvular heart disease ). Artificial heart valves can be separated into three broad classes: mechanical heart valves, bioprosthetic tissue valves and engineered tissue valves.
Aortic valve. The aortic valve is a valve in the heart of humans and most other animals, located between the left ventricle and the aorta. It is one of the four valves of the heart and one of the two semilunar valves, the other being the pulmonary valve. The aortic valve normally has three cusps or leaflets, although in 1–2% of the population ...
