How does myocardial delayed enhancement burden relate to right ventricular remodeling and contractility in patients with pulmonary hypertension?
In pulmonary hypertension, delayed enhancement at RV septal insertions correlates with RV remodeling and reduced regional contractility.
In PH, total delayed enhancement burden at the RV septal insertions is predicted by RV remodeling in response to increased afterload. Local fibrosis mass at the anterior septal insertion is associated with reduced regional longitudinal contractility at the base.
