Abstract Background: Patients with unrepaired Ebstein’s anomaly experience exercise intolerance, heart failure and premature mortality. Volumetric assessment of right ventricular function is difficult due to the complex anatomy of the right ventricle and tricuspid valve. Myocardial deformation indices are an early marker in other cardiac pathologies of ventricular dysfunction. Objectives: 1. Assess myocardial deformation in unrepaired Ebstein’s compared to healthy controls. 2. Investigate the relationships between myocardial deformation and exercise capacity. Methods: Myocardial deformation parameters (strain) were calculated using feature tracking from standard cardiac magnetic resonance cine images. Cardiopulmonary exercise results were included where available. Results: 36 patients… More >
