title: Left ventricular outflow tract obstruction and hemolytic anemia after mitral valve repair with a Duran ring.
abstract: We report a case of mitral valve repair with a Duran ring that was complicated by left ventricular outflow tract obstruction, mitral regurgitation, and hemolytic anemia. A 59-year-old man with severe mitral valve regurgitation underwent mitral valve repair, including a Duran ring annuloplasty. Postoperatively, left ventricular outflow tract obstruction developed and echocardiography revealed severe systolic anterior motion of the mitral valve. The patient then underwent mitral valve replacement with a 29-mm St. Jude valve.
