Change in Right Ventricular Strain after Cone Reconstruction of Ebstein's Anomaly: A CMR Feature Tracking Study

Background: Ebstein's anomaly (EA) is a rare congenital heart disease defined by apical displacement of the tricuspid valve. It is, however, deemed a disorder of development involving the entire right ventricular myocardium. The latest surgical approach for EA has been Da Silva's cone repair. Identifying a parameter that truly reflects myocardial function before and after cone repair remains challenging. Cardiovascular magnetic resonance feature tracking (CMR-FT) is a relatively new method to quantify myocardial contraction, which has demonstrated diagnostic and prognostic value in many diseases. We therefore aimed to assess the value of CMR-FT of the right ventricle (RV) in pre- and postoperative management of EA patients undergoing cone repair.
