Abstract Background: Although Cone reconstruction has been shown to improve biventricular function
over time, postoperative right ventricular dysfunction (RVD) is frequently observed, signiffcantly affecting
reoperation and long-term prognosis. This study aims to identify the predictors for postoperative RVD. Methods: This retrospective cohort study included 51 patients with Ebstein’s anomaly who underwent
the Cone reconstruction. RVD was deffned as right ventricular fractional area change (RV-FAC) less
than 35% and tricuspid annular plane systolic excursion (TAPSE) less than 17 mm through pre-discharge
echocardiography. Univariate and multivariate analyses were used to analyze the pre-operative predictors. Results: The median age at surgery… More >
