Iatrogenic Superior Vena Cava Syndrome after Cardiopulmonary Bypass Diagnosed by Intraoperative Echocardiography

Figure 1

The image in the left panel shows a two-dimensional presurgical midesophageal bicaval view obtained via transesophageal echocardiography (TEE) which demonstrates mild narrowing of the SVC at the SVC-right atrial junction. The image in the right panel is the same with the addition of color flow Doppler demonstrating no flow acceleration from the superior vena cava into the right atrium.
