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
Guidelines for aortic valve replacement. As long-term data on the survival and quality of life of people following valve replacement have become available, evidence-based guidelines for aortic valve replacement have been developed. These help healthcare professionals decide when aortic valve replacement is the best option for a patient.
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.
Percutaneous aortic valve replacement (PAVR), also known as transcatheter aortic valve implantation (TAVI) or transcatheter aortic valve replacement (TAVR), is the replacement of the aortic valve of the heart through the blood vessels (as opposed to valve replacement by open heart surgery).
An artificial heart valve is a device implanted into the heart of a patient to replace a dysfunctional native heart valve (valvular heart disease).. The human heart contains four valves: tricuspid valve, pulmonic valve, mitral valve and aortic valve.
An aortic valve repair will realistically be possible in the absence of relevant calcification or shrinking (retraction) of the aortic valve. Thus, congenital aortic stenosis may be treated by aortic valve repair. In acquired aortic stenosis valve replacement will be the only realistic option.

The durability of homograft valves is probably the same as for porcine tissue valves. Another procedure for aortic valve replacement is the Ross procedure (after Donald Ross) or pulmonary autograft. The Ross procedure involves going to surgery to have the aortic valve removed and replacing it with the patient's own pulmonary valve.
Mitral valve repair is a cardiac surgery procedure performed by cardiac surgeons to treat stenosis (narrowing) or regurgitation (leakage) of the mitral valve. The mitral valve is the "inflow valve" for the left side of the heart. Blood flows from the lungs, where it picks up oxygen, through the pulmonary veins, to the left atrium of the heart.
Sep 06, 2019 · How to Replace a Water Valve. Replacing a water valve is a relatively simply plumbing project. If your old valve is threaded, or screws directly onto the pipe, you can simply twist it off and replace it with a new valve.
With one type of operation, called transcatheter aortic valve replacement (TAVR), you get a thin tube that runs through a small opening in your leg and up to your heart. Your doctor uses that tube ...
