Congenital Partial Absence of the Left Pericardium Associated With Tricuspid Regurgitation

We report the case of a 47-year-old man who presented with several episodes of left precordial pain, one of which had been severe, but was unrelated to exertion or posture. Transthoracic echocardiography and cardiovascular magnetic resonance showed evidence of congenital partial absence of the left pericardium and severe tricuspid regurgitation. Both diagnoses were confirmed at surgery when the pericardial defect was repaired and the tricuspid valve was replaced at the same operation. He went on to make a good recovery.
