It’s Never Too Late: Spotting Congenital Absence of the Pericardium in an Older Adult

A 75-year-old male with a cardiopulmonary history presented with chest pain and dyspnea. He was hypertensive. An electrocardiogram showed paced rhythm. A high-sensitivity test showed his troponin T level was minimally elevated. Coronary angiography results were unremarkable. Chest radiography revealed an elevated cardiac apex, previously attributed to cardiomegaly. Echocardiography revealed a teardrop shaped heart in a nonstandard apical window. Computed tomography confirmed congenital absence of the left pericardium. Challenges of recognizing a rare condition are highlighted. Congenital absence of the pericardium, an often benign but rarely catastrophic condition, can masquerade for decades before diagnosis, underlining the importance of clinical vigilance in evaluating common cardiac complaints.
