Abstract Pr273: The Perioperative Application of Micro-probe Transesophageal Echocardiography Among Low-body-weight Pediatric Patients with Congenital Heart Diseases

Materials & Methods: Patient data was retrospectively collected from 395 cases of low-bodyweight pediatric patients (<5.0kg) with congenital heart diseases admitted to our hospital from November 1st, 2012 to December 31st, 2014. Among them 236 were male and 159 were female with the mean age of 2.1±1.7 months and mean body weight of 3.9±0.6 kg. Cardiac functions were all evaluated as NYHA class II~IV. Preoperative diagnoses, intraoperative guidance and postoperative assessments were performed using micro-probe TEE and the results were compared to that of transthoracic echocardiography (TTE) and of surgical exploration. The complications of micro-probe TEE and corresponding management were also recorded.
