Cesarean section under epidural anesthesia in a documented case of ruptured aneurysm of the sinus of valsalva.

Ruptured aneurysm of sinus of Valsalva (RSOV) occurring in pregnancy is a rare cardiac anomaly and it may be either congenital or acquired. Congenital sinus of Valsalva aneurysms are commonly associated with other structural defects such as ventricular septal defect (50-55%), aortic regurgitation (AR) (25-35%), bicuspid aortic valve (10-15%) and Marfan's syndrome (10%). RSOV in pregnancy accentuates the hemodynamic stress on maternal cardiovascular system and pose a significant challenge from obstetric anesthesia point of view. We report a case of 35-year-old documented patient of RSOV with mild AR presenting completely asymptomatic at 37 weeks 4 days of gestation. A successful elective lower segment cesarean section was conducted under epidural anesthesia.
