Measuring Atrioventricular Valve Regurgitation in Fontan Patients Using Cardiac MRI and the Association with Clinical Outcomes: A FORCE Study.

This is the first study evaluating different CMR measurements of atrioventricular valve regurgitation in a large cohort of Fontan patients.

Compared with atrioventricular valve regurgitation Standard , atrioventricular valve regurgitation AVV-AO had higher concordance with the reported categorical atrioventricular valve regurgitation using CMR.

Moderate and severe atrioventricular valve regurgitation determined by both CMR and echocardiography were associated with comparably increased hazards of adverse clinical outcomes.
