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.
二尖瓣脱垂（MVP）是一种常见的良性病症。然而，最近一些解剖学形式已被发现与危及生命的室性心律失常和心源性猝死有关。对MVP进行成像有望实现个性化的MVP风险评估。当今可用的非侵入性成像技术在MVP的诊断、预后和监测中发挥着越来越重要的作用。在本文中，我们将回顾关于致心律失常性MVP的现有证据，特别关注超声心动图和心脏磁共振成像（CMR）在识别MVP的良性和“恶性”形式方面的效用。本手稿的临床意义在于成像技术在改善MVP风险预测方面的价值，包括那些具有较高心源性猝死风险的心律失常性MVP病例。
