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 cardiac cycle. These changes are primarily due to the dynamic motion of the surrounding mitral valve annulus, a collageneous structure which attaches the mitral leaflets and the left atrium to the ostium of the left ventricle and the aortic root. Throughout the cardiac cycle, the annulus undergoes a sphincter motion, narrowing down the orifice area during systole to facilitate coaptation of the two leaflets and widens during diastole to allow for easy diastolic filling of the left ventricle. This motion is further enhanced by a pronounced three-dimensional configuration during systole, the characteristic saddle shape. These changes throughout the cycle
