We herein describe the previously unreported combination of partial anomalous venous connection to the superior vena cava combined with situs inversus totalis. Following peripheral contrast injection, bubbles appeared initially in the left atrium allowing the diagnosis of a supra-atrial connection to be made using transthoracic echocardiography, but this timing was not anymore reproduced during transesophageal echocardiography performed minutes later. Cardiac computed tomography allowed the final diagnosis to be made. This case emphasizes the importance of performing bubble studies both during transesophageal and transthoracic echocardiography.
