TALAVERA, María L. et al. Treatment of compression of the left main coronary artery in patients with pulmonary hypertension. Medicina (B. Aires) [online]. 2011, vol.71, n.5, pp.437-440. ISSN 0025-7680.

Chest pain is a frequent symptom in patients with pulmonary hypertension of any etiology. Its pathophysiology has not been clearly established, the proposed causes are ischemia due to increased right ventricle wall stress, transient increased pulmonary hypertension resulting in acute pulmonary artery dilatation and external compression of the left main coronary artery (LMCA) by a dilated pulmonary artery. We report and discuss here three cases where the association between chest pain and compression of the LMCA by a dilated pulmonary artery could be shown, and they were treated with coronary stenting.

Keywords : Pulmonary hypertension; Left main coronary artery; Stenting.
