It is a common fact that thousands of mothers die because of pregnancy around the world each year. Acomprehensive antepartum screening is of prime importance for the reduction of maternal mortality. Heart diseases are a major cause of maternal mortality. Atrial Septal Defect (ASD) is the most common acyanotic congenital heart disease.
A 22-year-old primiparous woman at 38 weeks of gestation applied to the gynecology department with palpitations and excessive fatigue. ASD was detected in the cardiology outpatient clinic. Due to fetal distress, emergency cesarean section (C-section) was performed under spinal anesthesia. The patient developed acute-onset hypotension and respiratory distress. In this report, we present a case with ASD that underwent emergency C-section due to fetal distress.
