Mitral valve severe form known as caseous calcification of the mitral valve that can be mistaken for intracardiac mass or thrombus. The closing of the mitral valve and the tricuspid valve constitutes the first heart sound (S1), which can be heard with a stethoscope. It is not the valve closure itself which produces the sound but the sudden cessation of blood flow, when the mitral and tricuspid valves close.. Abnormalities associated with the mitral valve can often be heard when listening with a stethoscope. The mitral valve is often also investigated using an ultrasound scan, which can reveal the size and flow
Mitral valve annuloplasty the native annulus and some of its natural dynamics. The goal of semi-rigid rings is to maintain coaptation and valve integrity during systole, while allowing for good hemodynamics during diastole. Rigid rings are designed to provide rigid support in large dilation and under high-pressure. Annuloplasty devices usually come in different sizes. The surgeon can estimate the dimensions of the patient’s mitral valve and decide on an appropriate ring size. Depending on the disease etiology, different approaches are taken. Surgeons can decide to "undersize" the device, "truesize" the device, or "oversize" it. Annuloplasty devices are classified by the U.S. Food and
