Compressão extrínseca da artéria coronária esquerda por dilatação aneurismática do tronco pulmonar em adolescente: involução após oclusão cirúrgica de comunicação interatrial seio venoso e plastia redutora do tronco pulmonar

Abstract

We report the case of an adolescent referred with initial diagnosis of pulmonary hypertension. Non-invasive investigation disclosed a sinus venous atrial septal defect with pulmonary hypertension. The hemodynamic study confirmed diagnosis, and also showed extrinsic compression of left main coronary artery by pulmonary trunk. Surgical closure of the defect in addition to pulmonary trunk plasty were undertaken. Two years after the surgery the patient is well, with clinical signs of mild pulmonary hypertension, and showing no evidence--also on echocardiogram--of left coronary artery trunk obstruction.
