Key result
CMR improves MVP risk prediction by identifying high-risk features like myocardial fibrosis and MAD.
Why the study?
Do noninvasive imaging techniques like echocardiography and CMR improve risk prediction for sudden cardiac death in patients with mitral valve prolapse?

Echocardiography and CMR are valuable for identifying malignant forms of mitral valve prolapse and improving risk prediction for sudden cardiac death.
May refine sudden cardiac death risk stratification in mitral valve prolapse; leaves open prospective validation before practice change.
Mitral valve prolapse (MVP) is a common and benign condition. However, some anatomic forms have been recently associated with life-threatening ventricular arrhythmias and sudden cardiac death. Imaging MVP holds the promise of individualized MVP risk assessment. Noninvasive imaging techniques available today are playing an increasingly important role in the diagnosis, prognosis and monitoring of MVP. In this article, we will review the current evidence on arrhythmogenic MVP, with special focus on the utility of echocardiography and CMR for identifying benign and "malignant" forms of MVP. The clinical relevance of this manuscript lies in the value of imaging technology to improve MVP risk prediction, including those arrhythmic-MVP cases with a higher risk of sudden cardiac death.

Fernández‐Friera et al. (2018) conducted a review in Arrhythmogenic mitral valve prolapse. Noninvasive imaging (Echocardiography and Cardiac Magnetic Resonance) was evaluated. Noninvasive imaging techniques, particularly cardiac magnetic resonance, improve risk prediction in mitral valve prolapse by identifying high-risk features like myocardial fibrosis and mitral annulus disjunction.
