Intraoperative Transesophageal Echocardiography in the Evaluation of Residual Gradients after Surgical Correction of Right and Left Ventricular Outflow Tract Obstructions

Background: Despite the large use of intraoperative Transesophageal Echocardiography (TEE) in congenital heart surgery, limited information is available regarding ventricular outflow tract obstruction. Objective: The aim of this study was to assess the reliability of the post-bypass TEE to detect residual gradients in patients with ventricular outflow obstruction. Patients and Methods: Post-bypass TEE peak systolic gradients of 127 patients...
