ABSTRACT
The most commonly reported coronary arterial malformation, in accounts of sudden deaths, is anomalous aortic origin of a coronary artery. Anomalous coronary arteries may arise from the left, right, or non-coronary sinuses of Valsalva. Importantly, although the left coronary artery from the right sinus has the worst prognosis, sudden death has been reported in all variants of origin from the various sinuses of Valsalva. This paper describes a technique that addresses all of the problems relating to anomalous aortic origin of a coronary artery from the wrong sinus of Valsalva. This technique includes the transection of the ascending aorta and pulmonary trunk, coronary arterial enlargement with a pericardial patch, and lateral translocation of the pulmonary trunk to the left pulmonary artery. Anomalous aortic origin of a coronary artery from the wrong sinus of Valsalva is a potentially lethal cardiac anomaly that can be corrected in all cases using this simplified surgical technique that addresses the major anatomic and physiological problems.

Atrioventricular septal defect with common atrioventricular junction is a relatively common congenital cardiac malformation. It sometimes presents challenging surgical problems, especially when seen in combination with tetralogy of Fallot. We describe herein our current concepts regarding surgical repair of atrioventricular septal defect with and without tetralogy, discussing indications for surgery, timing, technical aspects, and outcomes.

We report a case of idiopathic pulmonary trunk aneurysm in an infant, in which the main clinical picture was airway obstruction. Aneurysmorraphy was the chosen surgical approach and showed to be successful on 13 months follow-up.

We describe a simple and inexpensive system designed to deliver blood cardioplegia either diluted or at the patient's hematocrit, with controlled temperature and additive concentration. This system can be applied to any pump set, and suits any strategy for clinical myocardial preservation.

OBJETIVO: A valva aórtica bicúspide (VAB) está associada a maior prevalência de ectasia anulo-aórtica, aneurisma e dissecçäo da aorta ascendente. Este estudo investigou a quantidade de fibrilina-1 e elastina nos grandes vasos de portadores de VAB. MÉTODO:Amostras de tecidos foram colhidas da aorta ascendente e tronco da artéria pulmonar de 22 portadores de VAB e 16 portadores de valva aórtica tricúspide (VAT) submetidos a cirurgia cardíaca, incluindo seis portadores de valva aórtica normal, provenientes do programa de transplante. Imunofluorescência indireta e análise computadorizada de imagens foram utilizadas para quantificaçäo das proteínas na camada média dos vasos, expressas como densidade óptica integrada média (DOI). RESULTADOS: Na aorta, a DOI específica para fibrilina-1 foi 15 ± 8 no grupo bicúspide e 24 ± 7 no grupo tricúspide (p=0,001). Na artéria pulmonar, a DOI específica para fibrilina-1 foi 18 ± 10 no grupo bicúspide e 25 ± 9 no grupo tricúspide (p=0,07). A DOI específica para elastina na aorta foi 34 ± 13 no grupo bicúspide e 36 ± 19 no grupo tricúspide (p=0,31). Na artéria pulmonar, a DOI para elastina foi 30 ± 12 no grupo bicúspide e 29 ± 14 no grupo tricúspide (p=0,34). CONCLUSÕES: Os portadores de VAB apresentaram menor quantidade de fibrilina-1, mas näo elastina, na aorta ascendente e artéria pulmonar que os portadores de VAT normal ou doente. Estes achados podem explicar a maior incidência de dilataçäo e dissecçäo da aorta ascendente em portadores desta má-formaçäo da valva aórtica.
