Compression of the Left Main Coronary Artery by a Giant Pulmonary Artery Aneurysm
Jump to

We present a 70-year–old man who had a past medical history of dilated idiopathic pulmonary artery, incidentally diagnosed at the age of 23 years. He was asymptomatic until a year ago when he was admitted for an episode of anginal chest pain in the context of paroxysmal atrial fibrillation. At rapid rates, he showed pathological ST segment descent. A coronary angiography showed a slight stenosis of the left main coronary artery (LMCA). At that time, the mean pulmonary artery pressure was 36 mm Hg. After recovering sinus rhythm, the patient became asymptomatic and was discharged with β-blockers.
A year later, the patient was admitted with resting angina. The echocardiogram (Figure A) and the computed tomography-angio showed that the aneurysm had increased to 80 mm and compressed the LMCA (Figure B). This finding was …
