Abstract
Taussig-Bing heart is one of the conotruncal malformations. Embryologically, abnormal cardiac looping with misalignment of conotruncal septum result its complexity and great artery relationships. It was first described in 1949 by two outstanding physicians, Helen Brooke Taussig and Richard John Bing, who worked together at the John Hopkins Hospital in Baltimore. The original “Taussig-Bing heart” may be summarized as a double-outlet right ventricle (DORV) with semilunar valves side-by-side and approximately at the same height, bilateral conus, and a subpulmonary VSD. This original description has been broadened to include all kinds of double-outlet right ventricle with subpulmonary VSD. The evolution of surgical repair for the Taussig-Bing anomaly has progressed from atrial baffle procedures to arterial switch with VSD closure and intraventricular repair. For patients with Taussig-Bing type of DORV, the “arterial switch” operation, first reported in 1981, still appears to be the procedure of choice and can be performed in the neonatal period and also in patients with all types of great artery anatomy without ventriculotomy.
