Patent ductus arteriosus (PDA) presenting in an elderly patient is unusual. This report describes a 66-year-old woman who was scheduled to undergo surgical interruption of a calcified PDA without the assistance of extracorporeal circulation.A 66-year-old woman with a history of hypertension, atrial fibrillation, patent ductus arteriosus, pulmonary hypertension, and congestive heart failure was admitted because of an exacerbation of dyspnea. Cardiac catheterization revealed a left-to-right shunt across the PDA with a pulmonary-to-systemic flow ratio of 3.5:1. The coronary anatomy was normal. Transthoracic echocardiography showed markedly dilated main pulmonary artery (6 cm in diameter), tortuous right and left pulmonary arteries and moderate tricuspid and mitral regurgitation with an ejection fraction of 50%. PDA (10 mm in diameter) with prominent calcification was noted in an aortogram. Laboratory testing showed no abnormalities.
