Mitral insufficiency ring is typically secured to the annulus, or opening of the mitral valve, to provide additional structural support. In some cases, the "double orifice" (or 'Alfieri') technique for mitral valve repair, the opening of the mitral valve is sewn closed in the middle, leaving the two ends still able to open. This ensures that the mitral valve closes when the left ventricle pumps blood, yet allows the mitral valve to open at the two ends to fill the left ventricle with blood before it pumps. In general, mitral valve surgery requires "open-heart" surgery in which the heart is arrested and
Mitral valve stenosis left atrium correlates with the severity of the mitral stenosis. As the severity of the mitral stenosis increases, the pressure in the left atrium increases, and the mitral valve opens earlier in ventricular diastole. A mid-diastolic rumbling murmur with presystolic accentuation will be heard after the opening snap. The murmur is best heard at the apical region and is not radiated. Since it is a low-pitch sound, it is heard best with the bell of the stethoscope. Its duration increases with worsening disease. Rolling the patient toward left as well as isometric exercise will accentuate the murmur. A thrill might
