Case ReportsSevere intermittent intraprosthetic regurgitation after mitral valve replacement with subvalvular preservation.
Preservation of the subvalvular apparatus during mitral valve replacement preserves left ventricular function and improves long-term survival. Complications of subvalvular preservation include left ventricular outflow tract obstruction and prosthesis impingement. ⋯ Postoperative transesophageal echocardiography showed neither abnormal mitral regurgitation nor residual mass. The use of intraoperative transesophageal echocardiography could enable the detection of this rare complication.
