Technical performance scores associate with early prognosis of tetralogy of Fallot repair.

ABSTRACT:

Objective

This study aimed to investigate the relationship between technical performance scores (TPS) and the early prognosis of tetralogy of Fallot repair (TOF).

Methods

A retrospective study was conducted on TOF repair patients at our center from Oct 2017 to Oct 2022. Patients were classified into Class 1 (no residua), Class 2 (minor residua), or Class 3 (major residua) based on TPS derived from predischarge echocardiograms and need for reintervention. Statistical methods were used to assess the association between TPS and early prognosis.

Results

A total of 75 TOF repair patients (40% female, 60% male) were analyzed and categorized into TPS1 (24%), TPS2 (53.3%), and TPS3 (22.6%) based on pre-discharge echocardiographic findings. The median follow-up time was 7.0 months. The multivariable Cox regression analysis indicated that TPS3 scores are associated with a 12.68-fold increase in risk compared to TPS1 and TPS2 scores [95% CI = 12.68 (0.9∼179.28), P = 0.06]. The Spearman rank correlation analysis revealed a weak positive correlation between TPS classification and low cardiac output syndrome (r = 0.26, P = 0.03). However, there were no significant differences in ICU stay or duration of mechanical ventilation among the groups.

Conclusion

TPS3 after intracardiac TOF repair is associated with higher risk of early re-intervention, highlighting the importance of close follow-up and monitoring in this patient population. Patients who develop low cardiac output syndrome in the early postoperative period may have residual defects that require prompt identification.

Project description:BackgroundAdults with unrepaired tetralogy of Fallot (ToF) are common in developing countries. Long-term overload of the right ventricle places adult patients at risk for postoperative right heart failure after primary repair, which contributes to morbidity and mortality. The effect of pulmonary valve replacement (PVR) in reducing postoperative morbidity and mortality in adults has never been validated.MethodsWe conducted a retrospective cohort study in adults (age ≥18 years) with ToF undergoing primary repair from January 2014 to December 2019 at our institution. Patients were divided into three groups according to techniques used to enlarge the right ventricle outflow tract (RVOT). Baseline variables and perioperative outcomes were collected. The primary endpoint was operative mortality. Secondary endpoints were incidences of right heart failure and stage 3 acute kidney injury (AKI).ResultsA total of 56 patients were enrolled (mean age 41.5±11.7 years, 30 females, 53.6%). They were divided into three groups designated as the following: TA-PVR group for trans-annular patch enlargement with PVR; TA group for trans-annulus patch enlargement without PVR; and group AP for annulus preservation. Four patients (7.1%) died postoperatively, all due to right heart failure. All twelve patients in the TA-PVR group survived. There was no significant difference in mortalities among groups. Ten patients (17.9%) developed right heart failure after surgery with no significant difference among groups. Three patients (5.4%) developed stage 3 AKI after surgery, none belonging to the TA-PVR group, however, not statistically significant.ConclusionsRight heart failure is a common complication after primary repair of adult ToF. Trans-annulus patch enlargement should be cautiously selected in this population. PVR with trans-annulus patch enlargement may be a promising technique to protect against postoperative right heart failure and mortality when annulus preservation is not feasible.
