Minimally Invasive Mitral Valve Repair for Acute Papillary Muscle Rupture During Pregnancy.

Acute papillary muscle rupture during pregnancy is a rare cardiac condition with potential for 200% mortality. We describe a 28-year-old morbidly obese woman at 27 weeks gestation who presented with acute decompensated mitral regurgitation secondary to spontaneous papillary muscle rupture. After hemodynamic stabilization and caesarean delivery, we performed an emergent mitral valve repair through a minimally invasive right thoracotomy.
