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 stenosis acute severe mitral regurgitation. Severe mitral regurgitation usually results from a tear in one of the valve leaflets or the subvalvular apparatus. It can lead to pulmonary edema and hemodynamic compromise, necessitating urgent surgical mitral valve replacement. Other serious complications with PBMV usually relate to the technique of trans-septal puncture (TSP). The ideal site for TSP is the region of the fossa ovalis in the inter-atrial septum. Occasionally, however, the sharp needle used for TSP may inadvertently traumatize other cardiac structures, leading to cardiac tamponade or serious blood loss. Although the immediate results of PBMV are often quite gratifying, the
