title: Outflow tract obstruction after mitral valve repair without an annuloplasty ring.
abstract: We report that systolic anterior motion of the mitral valve with significant left ventricular outflow tract obstruction can occur after mitral valve reconstruction without using an annuloplasty ring. A 69-year-old male patient with mitral regurgitation and ischemic heart disease underwent combined mitral valve reconstruction without an annuloplasty ring, and coronary artery bypass grafting. Intraoperative transesophageal echocardiography performed at the end of the operation revealed systolic anterior motion of the mitral valve with significant outflow tract obstruction requiring a second pump run with return to cardiopulmonary bypass and additional mitral valve replacement during the same thoracotomy.
