Clinical application value of intraoperative transesophageal echocardiography in pediatric cardiac valvular disease

Background: To explore the value of intraoperative transesophageal echocardiography (TEE) in the surgical treatment of pediatric cardiac valvular disease. Methods: Transthoracic echocardiography (TTE) was performed in 64 children with cardiac valvular disease, of which 49 patients underwent TEE before and after cardiopulmonary bypass. Results: The coincidence rate of preoperative TEE with the surgical diagnosis on valvular lesions was 100%, higher than that of TTE (78%). TEE supplemented or corrected 10 cases of TTE valvular lesion diagnosis, improving the accuracy of valvular disease diagnosis. Besides, TEE can effectively evaluate the surgical results. Conclusions: Preoperative TEE can accurately diagnose valvular disease in children, which helps to develop a surgical plan. Postoperative TEE can find the remaining problems in time and improve the success rate of surgery.
