Taussig-Bing Heart” is a form of DORV characterized by subpulmonary VSD, Double conus and side- by- side great arteries and it is frequently associated with aortic coarctation, arch hypoplasia, subsortic obstruction and atypical coronary 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, but does not override the LV cavity at all and pulmonary stenosis does not occur. The VSD is not a membranous or conal septal or intrinsically defective and it is due to an abnormality of distal conal free walls and lies to the left of crista supraventricularis and above or antero-superior or posterosuperior 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, collectively termed as “Taussig-Bing complex”. A 14-year old acyanotic boy, presented with severe left-sided AV valve regurgitation and bradycardia. ECG revealed left sided morphologic right ventricular hypertrophy (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 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. The left-sided morphologic tricuspid valve is severely regurgitant due to rheumatic process. resulting in heart failure. Systemic AV valve regurgitation is a potential risk factor for morphologic RV dysfunction and without this complication, function well into late adulthood. Cardiac resynchronization therapy improves the hemodynamics of failing systemic right ventricle in patients with wide QRS on ECG, but is technically challenging. Early pacemaker placement is recommended in the setting of complete heart block with RV dysfunction, bradycardia or heart failure and urgently done during or after the surgical intervention when bradycardia is intolerable. The evolution of surgical repair for Taussig-Bing anomaly has progressed from atrial baffle procedures to arterial switch with VSD closure or intraventricular repair. Of these intraventricular repairs, Patrick-McGoon operation has been used for antero-posterior great artery anatomy by tunnelling the left ventricular flow anterior to the pulmonary valve. The other, Kawashima operation is used for side-by-side great artery anatomy by tunnelling left ventricular flow posterior to the pulmonary valve. The need for surgical interventions vary according to the associated defects and several options are available.
