Background As right ventricular dysfunction is a major cause of adverse outcome in patients with hypoplastic left heart syndrome, the aim was to assess right ventricular function and deformation after Fontan completion by performing 2‐dimensional cardiovascular magnetic resonance feature tracking in serial cardiovascular magnetic resonance studies. Methods and Results Cardiovascular magnetic resonance examinations of 108 patients with hypoplastic left heart syndrome (female: 31) were analyzed. Short‐axis cine images were used for right ventricular volumetry. Two‐dimensional cardiovascular magnetic resonance feature tracking was performed using long‐axis and short‐axis cine images to measure myocardial global longitudinal, circumferential, and radial strain. All patients had at least 2 cardiovascular magnetic resonance examinations after Fontan completion and 41 patients had 3 examinations. Global strain values and right ventricular ejection fraction decreased from the first to the third examination with a significant decline in global longitudinal strain from the first examination to the second examination (median, first, and third quartile: −18.8%, [−20.5;−16.5] versus −16.9%, [−19.3;−14.7]) and from the first to the third examination in 41 patients (−18.6%, [−20.9;−15.7] versus −15.8%, [−18.7;−12.6]; P‐values |
