A case of Eisenmenger syndrome with obstetric complication

Abstract

Background: Eisenmenger Syndrome is a serious complication of untreated congenital heart disease where long-standing hypertension causes reversal of blood flow, leading to hypoxemia. We report a 27-year-old female with a large atrial septal defect who later developed Eisenmenger syndrome with severe pulmonary hypertension. Her condition became complicated during pregnancy, which resulted in a missed abortion and medical termination. She later presented with cough and vomiting of dark brown material, and investigations showed gastric erosions. She was managed with supportive treatment, antibiotics, and acid-reducing therapy and improved clinically before discharge. This case highlights the importance of early diagnosis of congenital heart disease, careful monitoring in pregnancy, and multidisciplinary care to prevent serious complications.
