Abstract Objective: To explore application values of transesophageal echocardiograghy(TEE) in the hybrid therapy to balloon pulmonary valvuloplasty for young infants of pulmonary atresia with intact ventricular septum(PA/IVS). Methods: Twenty-five young infants with PA/IVS were diagnosed by transthoracic echocardiography(TTE) before operation. After general anesthesia with endotracheal intubation, all patients were inserted TEE probe to evaluate development of pulmonary valve annulus and right ventricle and instruct the surgeon to select the appropriate balloon. Pulmonary valve was punctured by needle, and then sheath and balloon were inserted with the guidance of TEE. All patients were performed by the balloon pulmonary valvuloplasty monitored by TEE, and the effect of valvuloplasty was evaluated by TEE immediately. Results: All patients were performed successfully for balloon pulmonary valvuloplasty with the guidance of TEE, and no severe complications occurred during the operation. The forward flow of pulmonary valve was unobstructed in 88.0% of the patients, and 80.0% of the patients had mild pulmonary valve insufficiency. The degree of tricuspid valve insufficiency was significantly reduced in 80.0% of the patients. The pulmonary valve blood flow velocity in the three patients was more than 3.0 m/s after surgery, who had to need right ventricle outflow tract reconstruction 10~25 months after balloon pulmonary valvuloplasty. Conclusions: TEE accurately makes preoperative evaluation for the patients with PA/IVS, real-time monitors the placement of sheath and balloon during operation, and may evaluate the effect of dilation immediately. TEE is a safe and effective guidance technique for the hybrid therapy of young infant patients with PA/IVS.
