BACKGROUND: The implantation of a coronary artery (CA) is critical for the arterial switch operation (ASO) done to treat @entity3886 ( @entity3886 ). @entity453 are risk factors for both early and late mortality after surgery. In this study, the methodology and effects of ASO surgery with coronary arteries from a single sinus were evaluated. METHODS AND RESULTS: From March 1999 to June 2006, 31 @entity1 were treated with ASO with coronary arteries from a single sinus in our hospital. They aged 11 hours 16 months (2.8 +/- 3.9 months) and weighted 2.3 7.8 Kg (3.1 +/- 2.5 Kg). 27 cases had @entity3886 and a @entity1757 ( @entity1757 ), and 4 had @entity3886 and an intact ventricular septum (IVS). During surgery, a CA button was implanted in the new proximal aorta with "trapdoor" technique or by inverting 90 degrees dorsally; pericardium or arterial augmentation was implanted at the base of the new major artery. The mortality rate after surgery was 25.8%. After 2-5 years of follow-up, 2 cases with residual shunting recovered spontaneously, 2 cases had residual pulmonary @entity432 (30-56 mmHg), and none of the @entity1 had any significant changes in @entity741 . CONCLUSION: The implantation of an abnormal coronary artery is practical and feasible; it can reduce both the occurrence of twisting and deforming in the coronary artery after implantation, as well as @entity741 after surgery. Thus, this could improve the surgical success and cure rates.
