Detecting and managing arrhythmic mitral valve prolapse.

Abstract

We describe a case of likely arrhythmic mitral valve prolapse (MVP) resulting in cardiac arrest, cardiopulmonary resuscitation, and initiation of extracorporeal membranous oxygenation. The case provides the clinical stimulus to review what knowledge exists, and what data gaps remain, to guide clinicians toward a proactive approach in managing arrhythmic mitral valve prolapse, a rare but potentially fatal condition. Since MVP is rare, performing several imaging modalities on every patient in whom there is a clinical suspicion would have a low yield. However, raising awareness of concerning features on history, electrocardiogram, and transthoracic echocardiography could improve the utility of more advanced imaging studies.
