B, Open position of a stenosed valve (left) and position of closed regurgitant valve (right). C, Hemodynamic effect of mitral stenosis. The stenosed valve is unable to open sufficiently during left atrial systole, inhibiting left ventricular filling. D, Hemodynamic effect of mitral regurgitation. The mitral valve does not close completely during left ventricular systole, permitting blood to reenter the left atrium.

41 Copyright © 2011, 2007 by Mosby, Inc., an affiliate of Elsevier Inc. Fig Mitral valvuloplasty performed by the Inoue technique. The catheter is placed in the mitral valve and the distal part of the Inoue balloon inflated (top). The balloon is then pulled back in the mitral valve and inflated for 10 to 15 seconds under fluoroscopic control (middle) until the waist of the balloon is no longer visible (bottom) and the balloon falls back into the left atrium.
