Abstract:
A 62-year-old female with severe symptomatic rheumatic mitral stenosis was referred for mitral valve replacement. A 27-mm Carbomedics mechanical mitral valve was placed using everting sutures. As the patient was weaned off cardiopulmonary bypass, she became hemodynamically unstable. Intraoperative transesophageal echocardiogram revealed a significant drop in left ventricular function along with severe LVOT obstruction. The Carbomedics prosthesis was replaced by a 27-mm St. Jude mechanical valve using noneverting sutures which relieved the LVOT obstruction. doi: 10.1111/jocs.12749 (J Card Surg 2016;31:376-379).
