TAUSSIG-BING MALFORMATION WITH STRADDLING OF THE 2 ARTERIOVENTRICULARVALVES - ECHOCARDIOGRAPHIC FINDINGS IN ONE CASE

The authors report the case of an infant with the Taussig-Bing malform ation and straddling of the two atrioventricular valves, the diagnosis of which was made by echocardiography and confirmed at surgery. Anato mic repair of the transposed great arteries was preceded by reconstruc tion of the interventricular septum which left the abnormal tricuspid subvalvular apparatus in the right ventricle and the abnormal mitral s ubvalvular apparatus in the left ventricle. Postoperative Doppler echo cardiography confirmed the absence of left ventricular outflow obstruc tion.
