Abstract:
Objective: To investigate the clinical value of transthoracic echocardiography (TTE) measured pulmonary artery parameters and pulmonary valve annulus Z scores for choosing the type of operation in complete repair of pediatric tetralogy of Fallot (TOF) Methods: A total of 143 patients received complete repair of pediatric TOF in our hospital were retrospectively studied. The patient's median age was 8 (1-171) months. Based on the type of operation, patients were divided into 2 groups: Trans-annular patch group, n=100 and Valve sparing repair group, n=43. Conventional TTE parameters, right ventricular outflow parameters and pulmonary valve annulus Z scores were compared between 2 groups; pulmonary valve annulus diameters measured by TTE and surgery were studied by correlation analysis. Results: Compared with Valve sparing repair group, Trans-annular patch group had decreased left ventricular end diastolic diameter (23.14±3.82) mm vs (25.23±4.56) mm, pulmonary valve annulus diameter (8.52±2.18) mm vs (10.01±2.61) mm and main pulmonary artery diameter (67.31 vs 82.91) all P<0.05. With reduced value of pulmonary valve annulus Z scores, the constituent ratio in Trans-annular patch group was gradually increasing and in Valve sparing repair group was gradually decreasing, all P<0.05. Correlation analysis indicated that pulmonary valve diameters measured by TTE and surgery had moderate agreement (r=0.581, P<0.001). Conclusion: TTE measured pulmonary valve annulus diameter, main pulmonary artery diameter and pulmonary valve annulus Z scores were the objective parameters provided to surgeon at pre-operation, which had clear clinical value.
