Abstract :

Taussig-Bing Heart” is a form of DORV characterized by subpulmonary VSD, double conus and sideby- side great arteries. It was first described in 1949 by Helen B.Taussig and Richard J.Bing at John Hopkins hospital, Baltimore in a 5.5 year old girl. Richard Van braagh differentiated it from transposition of great arteries in which pulmonary-mitral continuity is present, but it is absent in Taussig-Bing heart. The dilated pulmonary artery overrides the ventricular septum and pulmonary stenosis does not occur. The VSD is due to an abnormality of distal conal free walls, lies to the left of crista supraventricularis and above or antero-superior or postero-superior to the septal band. Subsequently described a spectrum of Taussig-Bing hearts depending on the overriding of pulmonary artery as right sided, intermediate, left-sided and malalignment of infundibular septum is a fundamental requisite to define these hearts as “Taussig-Bing complex”. A 14-year old acyanotic boy, presented with severe left-sided AV valve regurgitation due to rheumatic process. resulting in heart failure and bradycardia. ECG revealed left sided morphologic RVH as evidenced by a loss of septal Q waves in left precordial leads, suggesting ventricular inversion and a congenital high grade AV block. Echocardiography revealed the primary origin of both L-transposed great arteries from the left-sided morphologic right ventricle, suggesting a ‘double-outlet morphologic right ventricle’ with ‘double discordance’ and a subpulmonary VSD of Taussig-Bing type. Left AV valve replacement with intraventricular repair is preferred in this child since the malformation is consistent with Taussing-Bing type of DORV with L-transposition.
