Why the study?
This study was conducted to determine the longitudinal changes in systemic ventricular function and atrioventricular valve regurgitation after total cavopulmonary connection.
Does ventricular morphology (dominant RV vs dominant LV) affect longitudinal systemic ventricular function and atrioventricular valve regurgitation after the Fontan procedure?
Population
620 patients who underwent TCPC between 1994 and 2021
Comparison
Dominant right ventricle vs dominant left ventricle
Design
Retrospective longitudinal cohort study

Dominant RV Fontan patients may need intensified long-term ventricular surveillance after 10 years; extends morphology-outcome data but leaves open targeted interventions.
Does ventricular morphology (dominant RV vs dominant LV) affect longitudinal systemic ventricular function and atrioventricular valve regurgitation after the Fontan procedure?
In patients undergoing the Fontan procedure, those with a dominant right ventricle experience worse long-term systemic ventricular function and more atrioventricular valve regurgitation after 10 years compared to those with a dominant left ventricle.
