Case report: arrhythmic mitral valve prolapse syndrome—are risk factors underdiagnosed?

Abstract

Abstract Background Arrhythmic mitral valve prolapse syndrome (ARMV) is a recognized but underdiagnosed disease pattern. Risk factors for ARMV are established but not very well known, and the association of the structural abnormality with ventricular arrhythmias is incompletely understood. Case summary Here, we present the case of a young man who presented at our hospital for radiofrequency catheter ablation and mitral valve surgery after two episodes of survived sudden cardiac arrest. We discuss the diagnostic and therapeutic strategies that were used. We shine light on the risk factors for ARMV and why early identification is crucial. We address the topic of primary prevention and its limitations. Finally, we discuss different treatment modalities for patients with ARMV. Discussion More awareness for ARMV is crucial. A consensus statement on clinical management exists, but scientific gaps in prospective data for primary prevention need to be filled and there is a need for a better understanding of the pathogenesis of ARMV.
