Tratamento com stent em tronco de artéria coronária esquerda por compressão do tronco da artéria pulmonar em paciente com hipertensão pulmonar esquistossomótica

Abstract

Pulmonary hypertension is frequently associated to chest pain with anginous characteristics and its etiology is uncertain. Extrinsic compression of the left main coronary artery by the pulmonary artery is a treatable cause and should be taken into consideration. We present the case of a patient with pulmonary hypertension of schistosomotic etiology presenting angina due to compression of the left main coronary artery, who was treated with an intracoronary stent. Signs and symptoms of ischemia were completely resolved and a late follow-up intravascular ultrasound confirmed the vessel patency.
