Left main coronary artery (LMCA) disease caused by external compression by a dilated main pulmonary artery (MPA) is an uncommon clinical entity but is one of the reversible causes of chest pain in patients with pulmonary hypertension. Traditionally, treatment of LMCA disease involves coronary artery bypass graft surgery. However, for LMCA compression by a dilated MPA, coronary angioplasty with stenting has recently been reported to have good outcomes and might be more suitable in some patients with high risk associated with surgery. Herein, we describe a 54-year-old man with pulmonary arterial hypertension and external compression of the LMCA by the dilated main pulmonary artery that was treated with angiographic and intravascular ultrasound-guided coronary angioplasty and stenting. Also we briefly review current literatures about LMCA compression by a dilated MPA.
