Atrial function in Fontan patients assessed by CMR: Relation with exercise capacity and long-term outcomes

ObjectiveTo assess the role of atrial function on exercise capacity and clinical events in Fontan patients.DesignWe included 96 Fontan patients from 6 tertiary centers, aged 12.8 (IQR 10.1–15.6) years, who underwent cardiac magnetic resonance imaging and cardiopulmonary exercise testing within 12 months of each other from 2004 to 2017.
