Mitral valve stenosis secondary to mitral stenosis is severe, the P (pulmonic) component of the second heart sound (S) will become loud. An opening snap that is a high-pitch additional sound may be heard after the A (aortic) component of the second heart sound (S), which correlates to the forceful opening of the mitral valve. The mitral valve opens when the pressure in the left atrium is greater than the pressure in the left ventricle. This happens in ventricular diastole (after closure of the aortic valve), when the pressure in the ventricle precipitously drops. In individuals with mitral stenosis, the pressure in the
Mitral valve stenosis individuals with a crisp opening snap, score < 8, and no calcium in the commissures. Treatment also focuses on concomitant conditions often seen in mitral stenosis: Mitral valvuloplasty is a minimally invasive therapeutic procedure to correct an uncomplicated mitral stenosis by dilating the valve using a balloon. Under local anaesthetic, a catheter with a special balloon is passed from the right femoral vein, up the inferior vena cava and into the right atrium. The interatrial septum is punctured and the catheter passed into the left atrium using a "trans-septal technique." The balloon is sub-divided into 3 segments and is dilated
