Key result
Having ≥2 preoperative risk factors (RV end-diastolic volume index >200 ml/m2, RV-EF <40%, age >50 years) significantly increased the odds of death or need for ECMO (OR 18.5; P=0.001).
Why the study?
Postoperative RV failure is a severe complication following tricuspid valve surgery for Ebstein anomaly, but the preoperative predictability of postoperative mortality and morbidity remained unclear.
Do preoperative risk factors (RV EDVI >200 ml/m2, RV-EF <40%, age >50 years) predict postoperative mortality and morbidity in patients undergoing surgery for Ebstein's anomaly?
Cohort (n=70)
No
Do preoperative risk factors (RV EDVI >200 ml/m2, RV-EF <40%, age >50 years) predict postoperative mortality and morbidity in patients undergoing surgery for Ebstein's anomaly?
Odds Ratio: 18.5
p-value: p=0.001
Preoperative RV end-diastolic volume index >200 ml/m2, RV-EF <40%, and age >50 years strongly predict postoperative mortality and morbidity in patients undergoing surgery for Ebstein's anomaly.

Preoperative RV size, function and age may aid risk stratification in Ebstein surgery; leaves open prospective validation before guiding decisions.
Agua et al. (2018) conducted a cohort in Ebstein's anomaly (n=70). ≥2 preoperative risk factors (RV end-diastolic volume index >200 ml/m2, RV-EF <40%, age >50 years) vs. <2 preoperative risk factors was evaluated on Death or the need for extracorporeal membrane oxygenation (OR 18.5, p=0.001). Having ≥2 preoperative risk factors (RV end-diastolic volume index >200 ml/m2, RV-EF <40%, age >50 years) significantly increased the odds of death or need for ECMO (OR 18.5; P=0.001).
