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.
St. Jude Medical was founded in 1976 to further develop bi-leaflet artificial heart valves, which were originally created in 1972 at the University of Minnesota. [4] [5] St. Jude Medical's bi-leaflet valve was developed in large part by Dr. Demetre Nicoloff of the University of Minnesota and St. Jude Medical employee Don Hanson.
In 1976, he founded St. Jude Medical where his team engineered the first bileaflet mechanical heart valve, which reduced the frequency of blood clots in patients. It still dominates the mechanical valve replacement market. [4] [5] In 1982, Villafana founded GV Medical, which developed a device to open blood vessels open. [6]

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 with Marfan syndrome.
Current methods for aortic valve replacement include open-heart surgery, minimally invasive cardiac surgery (MICS), surgical aortic valve replacement (SAVR) and percutaneous or transcatheter aortic valve replacement (TAVR; also PAVR, PAVI, TAVI). A cardiologist can evaluate whether a heart valve repair or valve replacement would be of benefit. [1]
Mitral valve repair is mainly used to treat stenosis (narrowing) or regurgitation (leakage) of the mitral valve. [citation needed] A mitral balloon valvuloplasty enlarges the valve opening to allow greater oxygenated blood flow into the left ventricle, and since severe mitral regurgitation can be a major complication, degrees of stenosis, regurgitation, and valve anatomical features are taken ...
