Case ReportsLeft ventricular outflow obstruction: a complication of mitral valvuloplasty.
Thirty-two patients with severe mitral regurgitation underwent Carpentier mitral valvuloplasty. Postoperatively, three of these patients developed clinical and echocardiographic evidence of left ventricular outflow tract obstruction. ⋯ Outflow obstruction postoperatively was caused by systolic anterior motion of the mitral valve. Because this potential complication of Carpentier mitral valvuloplasty produced significant hemodynamic effects in two patients, echocardiography should be routinely performed after this operation.
