title: Short- and mid-term outcomes of total correction of Taussig-Bing anomaly.
abstract: Double-outlet right ventricle (DORV)/Taussig-Bing (TB) anomaly is the second most common type of DORV. This study evaluates our experience and outcomes of total correction of DORV-TB anomaly at King Abdulaziz Cardiac Center. We conducted a retrospective study for all cases of TB anomaly repaired between June 2001 and April 2009. Patients were divided into two groups: Group A included patients repaired with arterial switch operation, and group (B) included patients repaired with Rastelli procedure. Thirteen patients with TB anomaly underwent total correction. There were 5 male (38%) and 8 female (62%) patients. Mean age and weight at surgery were 6.8 ± 6 weeks and 3.6 ± 0.7 kg, respectively. Of the 13 patients, 9 (69%) were in group A, and 4 (31%) were in group B. Aortic arch abnormalities were present in 9 patients (69%); abnormal coronary artery patterns were present in 7 patients (54%); side-by-side great arteries were present in 5 patients (38%); dextrotransposition of the great arteries was present in 7 patients (54%); and levo-malposition of the great arteries was present in 1 patient (8%). At postoperative follow-up, 4 patients (31%) had developed either left- or right-ventricular outflow tract (VOT) obstruction requiring surgical and/or catheter intervention. There was no early mortality, but there was 1 late mortality caused by left-ventricle dysfunction. DORV-TB is often associated with other congenital cardiac anomalies. In general, total repair is feasible in the majority of patients with satisfactory results and improved outcome. Residual lesion and development of VOT obstruction can occur, requiring close follow-up and intervention for residual lesion.
