Does CMR quantification of mitral regurgitation predict the development of symptoms or indications for surgery better than CMR-derived ventricular volumes in patients with mitral regurgitation?
CMR quantification of mitral regurgitation provides superior prognostic discrimination compared to standard ventricular volumes, potentially identifying patients who would benefit from early surgery.
CMR quantification of mitral regurgitation was associated with the development of symptoms or other indications for surgery and showed better discriminatory ability than the reference-standard CMR-derived ventricular volumes. CMR may be able to identify appropriate patients for early surgery, with the potential to change clinical practice, although the clinical benefits of early surgery require confirmation in a clinical trial.
Myerson et al. (Tue,) studied this question.
