ABSTRACT

Objective:

Pulmonary annulus index is used to predict the application value of transannular patch in children with tetralogy of Fallot.

Methods:

A retrospective analysis of 130 patients with pediatric heart disease diagnosis of TOF and undergoing TOF repair in Beijing Anzhen Hospital affiliated to Capital Medical University from December 2018 to December 2019, 112 cases were included in this study, 18 cases were excluded. They were divided into TAP group and no TAP group, related values of pulmonary annulus and aortic annulus were measured. The pulmonary annulus index, the pulmonary annulus Z-score and main pulmonary artery Z-score were calculated to do statistically analyze.

Results:

A total of 112 patients, average age(22.87±12.21) months; 66 males and 46 females; weight( 9.94±4.08)kg; 3 cases died, 1 case died of sepsis caused by pulmonary infection, 1 case died of low cardiac output syndrome, and 1 case died of multiple organ failure. 62 cases(55.8%) did not transannular patch, 50 cases(44.2%) transannular patch. The pulmonary annulus Z-score, main pulmonary artery Z-score and PAI in TAP group were smaller than those in no TAP group( P<0.05). Receiver operator curves( ROC) analysis showed that the cut-off value of PAI at 0.53 AUC was 0.85, the sensitivity was 75%, the specificity was 80%; the cutoff value of pulmonary annulus at -1.98 AUC was 0.88, the sensitivity was 80%, the specificity was 71%; the cutoff value of main pulmonary artery at -2.12 AUC was 0.87, the sensitivity was 77%, and the specificity was 87%. When the critical value of PAI(>0.53) and main pulmonary artery Z-score(>2.12), 88.2% of the children could avoid TAP, and 94% of the children could avoid TAP when the critical value of pulmonary annulus Z-score(> -1.91) and main pulmonary artery Z-score(>-2.12) were combined.

Conclusion:

The predictive effect of pulmonary annulus index as a simple and effective predictor of TAP in TOF radical operation is the same as that of pulmonary annulus Z-score. Combining either with main pulmonary artery Z-score was the most accurate method of prediction.
