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 annuloplasty Drug Administration (FDA) as medical devices. Mitral valve annuloplasty Mitral valve annuloplasty is a surgical technique for the repair of leaking mitral valves. Due to various factors, the two leaflets normally involved in sealing the mitral valve to retrograde flow may not coapt properly. Surgical repair typically involves the implantation of a device surrounding the mitral valve, called an annuloplasty device, which pulls the leaflets together to facilitate coaptation and aids to re-establish mitral valve function. Mitral regurgitation is the most common form of mitral valve dysfunction. Today more than 2.5 million Americans are estimated to be affected by mitral
