title: Extrinsic compression of left main coronary artery from aneurysmal dilation of pulmonary trunk in a adolescent: involution after surgery occlusion of sinus venosus atrial septal defect and pulmonary trunk plasty for reduction.
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.
