ABSTRACT
The objective of this paper was to describe the outcomes in patients submitted to arterial switch operation and to analyze the predictors of in-hospital mortality and further need of re-operation at a single-center institution. Between September 1995 and January 2014, 128 consecutive arterial switch operations were performed. Surgical mortality during this period was analyzed retrospectively, and a follow-up analysis of the survivors was conducted. Surgical era, cardiopulmonary bypass time (p = 0.001), and diagnosis category (p = 0.025) influenced in-hospital mortality. The estimated overall survival for the 91 hospital survivors was 96.8, 96.4, and 96.2 % at 5, 10, and 15 years, respectively. The median follow-up time was 67 months (range 0.71-222 months). Three patients (5 %) presented severe aortic regurgitation. Right ventricle outflow tract systolic gradient by echocardiography was above 60 mmHg in 2 %. Late re-interventions occurred in 12 (13 %) patients with mean time of 64 ± 34 months after the initial procedure. Actuarial freedom from re-interventions at 5, 10, and 15 years was 96.4, 69.7, and 61.9 %, respectively. Arterial switch operation remains the procedure of choice in patients with transposition of great arteries. It can be performed even in middle-volume institutions, leading to the same middle- and long-term outcomes of high-volume institutions. Early high mortality rate may occur due not only to learning curve, but also to cardiopulmonary bypass time and ventricular septal defect closure.

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.

Relatamos o caso de um adolescente encaminhado com o diagnóstico de hipertensão pulmonar. A investigação não invasiva detectou comunicação interatrial seio venoso com sinais de hipertensão pulmonar. No estudo hemodinâmico o diagnóstico foi confirmado, sendo também notada compressão esquerda pelo tronco pulmonar. O paciente foi submetido à oclusão cirúrgica da comunicação interatrial e à plastia redutora do tronco pulmonar. Dois anos após o procedimento, o paciente encontra-se bem, com sinais clínicos e ecocardiográficos de hipertensão pulmonar discreta e sem evidências, também pelo ecocardiograma, de obstrução do tronco da artéria coronária esquerda.
