Emergency mitral valve replacement and cesarean section in parturients: Two case reports

Abstract

Cardiac surgery during pregnancy using cardiopulmonary bypass has a maternal mortality rate (MMR) of about 3-15%. Cardiopulmonary bypass, in addition, alters placental perfusion, which can increase infant mortality. Here, we report two cases of parturients with severe mitral stenosis, who developed acute mitral regurgitation (MR) after percutaneous transluminal mitral commissurotomy (PTMC) due to anterior mitral leaflet tear. They were posted for emergency mitral valve replacement (MVR) followed by cesarean section. Altering the routine cardiopulmonary bypass and anesthesia protocol resulted in a favorable maternal and fetal outcome.
