Case report


Following images and video show a case of double outlet right ventricle with D-transposition of the great arteries (Taussig-Bing form of double outlet right ventricle). The young mother (G2P1) with non contributive history was referred to our department for evaluation of the cardiac abnormality. No other anomalies were found. The mother opted for the termination of the pregnancy.

Images 1, 2: The image 1 shows lateral 4-chamber view of the heart with no evident anomaly, but the outflow tract view (image 2) shows a large ventricular septal defect of the heart.


Image 3, 4, 5, and 6: The images show cardiac outflows with aorta anterior and to the right and pulmonary artery posterior on the left with sub-pulmonic ventricular septal defect.



Image 7, 8: The images show three-vessel view of the heart with just two vessels - the aorta and superior vena cava. Pulmonary artery is not seen as it courses below the aorta in parallel manner.


Image 9, 10: The images show parallel course of the aorta and pulmonary artery - the anterior vessel forming a wide arch represents the aorta with neck vessels arising from the arch.


Image 11, 12: The images show parallel course of the aorta and pulmonary artery arising from the right ventricle of the heart.


Video 1: The video summarizes the findings described above.

Taussig-Bing anomaly (Taussig-Bing syndrome) represents combination of transposition of the aorta to the right ventricle and malposition of the pulmonary artery with subpulmonary ventricular septal defect. The anomaly bears the names of Dr. Helen Taussig and Dr. Richard Bing, coworkers at The Johns Hopkins Hospital in Baltimore.
