In this cohort, LV and RV ECV values were positively correlated, indicating an adverse ventricular-ventricular interaction at the tissue level. Increased ECV was associated with RV volume overload and arrhythmia. These findings may lead to future studies exploring the role of ECV in improving risk stratification and guiding therapeutic interventions.

In young patients with AS, myocardial ECV is significantly elevated compared with control subjects and is associated with echocardiographic indexes of diastolic dysfunction. ECV measured by CMR may be a useful method for risk stratification and monitoring therapies targeting fibrosis.
