Intraoperative Transesophageal Echocardiogram Using an Intracardiac Ultrasound Catheter in a Congenital Heart Surgery: A Case Report
- 209 Downloads
Transesophageal echocardiography (TEE) during cardiac surgery is a routine procedure. The use of pediatric TEE probes is limited in small infants weighing less than 5 kg. Recent reports have shown the safety of monoplane intravascular ultrasound catheters in transesophageal echocardiograms. This report describes the case of a newborn with total anomalous pulmonary venous return who underwent cardiac surgery. A pre- and postbypass TEE examination was performed, with successful visualization of the cardiac anatomy and function and no complications.
