چکیده
OBJECTIVES The arterial switch operation (ASO) is the method of choice for the Taussig-Bing heart. The aim of the study was to analyse the long-term outcome of correction of the Taussig-Bing heart. METHODS Between 1986 and 2011, 44 infants, including 18 newborns, underwent an ASO. The staged and the primary approach were used in 9 and 35 patients, respectively. Aortic arch (AA) obstruction (n = 26) and right ventricle outflow tract obstruction (n = 34) were common. The mean age at corrective surgery was 112.9 days; the mean weight was 4.17 kg. RESULTS There were 1 early and 4 late deaths. Overall survival was 88% at 15 years, with a mean follow-up of 9.2 years. Freedom from reoperation was 67% at 15 years of follow-up. Eight and 6 patients required right and left ventricular outflow tract surgery, respectively, including resection of the right ventricular outflow tract obstruction (n = 8), a transanular patch (n = 6), aortic valve reconstruction (n = 3), aortic valve replacement (n = 2) and AA reoperation (n = 4). Freedom from aortic regurgitation >mild or aortic valve replacement/reconstruction was 76% at 15 years of follow-up. Freedom from any event was 56% at 15 years of follow-up. All patients are in sinus rhythm, and biventricular function is well-preserved in 95% of patients. All patients are doing well; 86% of them are without medication. CONCLUSIONS Corrective surgery offers excellent survival benefits and encouraging long-term functional outcomes, regardless of the coronary anatomy and associated lesions. Normal biventricular function is preserved in the vast majority of patients, and >3/4 of patients are without cardiac medication. Nevertheless, TBH associated with a complex anatomy continues to be a risk factor for long-term morbidity, and redos and reinterventions are equally common on both outflow tracts. Progressive neoaortic regurgitation and neoaortic root dilatation might be a problem in the future; therefore, close lifelong surveillance of patients is necessary.

Taussig–Bing anomaly is a rare congenital cardiac malformation, first described in 1949 by Helen B. Taussig and Richard J. Bing. The second most common variant of double outlet right ventricle, the anomaly was originally distinguished by a transposed aorta arising entirely from the right ventricle, a pulmonary artery overriding a ventricular septal defect (VSD), side-by-side great vessels, and ...

The third patient had an usual coronary pattern, and f...
