Echocardiographic diagnosis of left ventricular outflow tract obstruction after mitral valvuloplasty with a flexible Duran ring.
We report on a patient in whom left ventricular outflow obstruction developed after mitral valve repair with a flexible Duran ring. This complication has been reported in 4.5% to 21% of patients when a rigid Carpentier ring was used but was thought to be eliminated with the use of flexible rings.
