Abstract
Congenital Bochdalek diaphragmatic hernia (DH) is often diagnosed incidentally in adulthood. It is recommended that all cases of DH be repaired immediately at diagnosis since acute presentation after the complications have already developed has higher morbidity and mortality. A 47-year-old male presented with Grade III angina and dyspnea. A routine chest radiograph revealed bowel shadows in the right thorax, and subsequent computerized tomography (CT) scan confirmed the same. Coronary angiogram revealed coronary artery disease which needed surgery. Off-pump coronary artery bypass grafting followed by DH repair under one-lung ventilation.
