Extrinsic compression of left main coronary artery due to pulmonary artery aneurysm and pulmonary hypertension

Radiol Case Rep. 2024 Apr 24;19(7):2837-2840. doi: 10.1016/j.radcr.2024.03.073. eCollection 2024 Jul.

Abstract

Idiopathic pulmonary arterial hypertension is a serious condition that carries a poor prognosis. While exertional dyspnea is the most common symptom, angina like chest pain, most often due to right ventricle ischemia, may occur at advanced stages. We present a patient with pulmonary hypertension symptomatic for dyspnea and angina in whom computed coronary tomography angiography showed compression of the left main coronary artery by a large pulmonary artery aneurysm. Percutaneous coronary intervention and stenting was performed resulting in significant clinical improvement. This case emphasizes the role of different cardiovascular imaging modalities for the diagnosis of rare conditions.
