Mitral valve stenosis procedure does not provide permanent relief from mitral stenosis. Regular follow-up is mandatory, to detect restenosis. Long-term follow-up data from patients undergoing PBMV indicates that up to 70-75% individuals can be free of restenosis 10 years following the procedure. The number falls to about 40% 15 years post-PBMV. Mitral valve stenosis Mitral stenosis is a valvular heart disease characterized by the narrowing of the orifice of the mitral valve of the heart. Signs and symptoms of mitral stenosis include the following: Fatigue and weakness increase with exercise and pregnancy. The natural history of mitral stenosis secondary to rheumatic fever (the
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
