Mitral valve replacement Mitral valve replacement Mitral valve replacement is a cardiac surgical procedure in which a patient’s diseased mitral valve is replaced by either a mechanical or bioprosthetic valve. Mitral valve replacement is performed when the valve becomes too tight (mitral valve stenosis) for blood to flow into the left ventricle, or too loose (mitral valve regurgitation) in which case blood can leak back into the left atrium and thereby back into the lung. Mitral valve disease can occur from infection, calcification, inherited collagen disease, or other causes. Since a mitral valve replacement is an open heart surgical procedure, it requires placing
Mitral valve annuloplasty Drug Administration (FDA) as medical devices. Mitral valve annuloplasty Mitral valve annuloplasty is a surgical technique for the repair of leaking mitral valves. Due to various factors, the two leaflets normally involved in sealing the mitral valve to retrograde flow may not coapt properly. Surgical repair typically involves the implantation of a device surrounding the mitral valve, called an annuloplasty device, which pulls the leaflets together to facilitate coaptation and aids to re-establish mitral valve function. Mitral regurgitation is the most common form of mitral valve dysfunction. Today more than 2.5 million Americans are estimated to be affected by mitral
