Emergency MVR before cesarean section yields favorable maternal and fetal outcomes in two cases.
Case Report (n=2)
Emergency mitral valve replacement and cesarean section with modified cardiopulmonary bypass protocols can yield favorable outcomes in pregnant patients with acute severe MR complicating PTMC.
Acute MR post-PTMC in pregnancy may require emergency MVR; leaves open optimal protocols and outcomes data.
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.

Singh et al. (2016) conducted a case report in Severe mitral stenosis with acute mitral regurgitation (n=2). Emergency mitral valve replacement followed by cesarean section with altered cardiopulmonary bypass and anesthesia protocol was evaluated on Maternal and fetal outcome. Emergency mitral valve replacement followed by cesarean section with altered cardiopulmonary bypass and anesthesia protocols resulted in favorable maternal and fetal outcomes in two parturients.
