OBJECTIVE: To investigate the effect of transesophageal echocardiography (TEE) in the surgical treatment of tetralogy of Fallot.

PATIENTS AND METHODS: 98 patients with tetralogy of Fallot received and cured by Zhengzhou Cardiovascular Hospital (Zhengzhou No. 7 People’s Hospital) from January 2015 to January 2017 were selected as the study objects. All patients were examined by TEE before surgery, and the pulmonary artery index (PAI) and pulmonary vein index (PVI) were measured, so as to analyze the effect of TEE in the surgical treatment of tetralogy of Fallot. Among the 98 patients, 12 patients were diagnosed with intensive care unit (ICU) retention, 23 patients were diagnosed with respirator assisted respiration extension, 8 patients were diagnosed with low cardiac output syndrome, and 10 patients were diagnosed with respiratory tract infection, which indicated that TEE could diagnose conditions after radical operation of tetralogy of Fallot.

RESULTS: The calculation results showed that the PAI was (171.37±58.39) mm2/m2 and the PVI was (282.46±54.37) mm2/m2. The Pearson correlation analysis showed that the correlation between them was good (r=0.821, p<0.001). TEE had good specificity and sensitivity in the diagnosis of respirator assisted respiration extension, ICU retention, and low cardiac output syndrome after radical surgery of tetralogy of Fallot.

CONCLUSIONS: TEE can predict the occurrence of respirator assisted respiration extension, ICU retention and low cardiac output syndrome of patients after radical surgery by evaluating the PAI and PVI of patients with tetralogy of Fallot.
