Congenitally Corrected Transposition of Great Arteries Associated with Interrupted Aortic Arch Type A, Complex and Rare Anatomy Detected by Echocardiography: A Case Report

We report an extremely rare case of congenitally corrected transposition of great arteries (CCTGA) (Pic. 1) associated with interrupted aortic arch (IAA) type A (Pic. 2) and a ventricular septal defect (VSD), in a preterm infant born at 36 weeks of gestation with a birth weight of 2.5 kg. This baby was diagnosed in utero with a large VSD and severe coarctation of the aorta. A comprehensive echocardiographic examination confirmed the diagnosis and revealed that the congenitally corrected transposition of great arteries was associated with Interrupted aortic arch type A. A review of the literature revealed only one similar case, reported earlier by Cottrell, et al. [1]. In their case, the initial diagnosis was confirmed angiographically as 2D and color Doppler echocardiography were not available in their center. The clarity of echocardiographic images obtained in our institution enabled us to make this diagnosis without needing additional imaging modalities. The infant was managed successfully as he underwent an aortic arch repair using an end-to-end anastomosis and a pulmonary artery (PA) band placement as a palliation towards second stage repair.
