In light of the adverse prognosis related to severe mitral regurgitation, heart failure, or sudden cardiac death in a subset of patients with mitral valve prolapse (MVP), identifying those at higher risk is key. For the first time in decades, researchers have the means to rapidly advance discovery in the field of MVP thanks to state-of-the-art imaging techniques, novel omics methodologies, and the potential for large-scale collaborations using web-based platforms. The National Heart, Lung, and Blood Institute recently initiated a webinar-based workshop to identify contemporary research opportunities in the treatment of MVP. This report summarizes 3 specific areas in the treatment of MVP that were the focus of the workshop: 1) improving management of degenerative mitral regurgitation and associated left ventricular systolic dysfunction; 2) preventing sudden cardiac death in MVP; and 3) understanding the mechanisms and progression of MVP through genetic studies and small and large animal models, with the potential of developing medical therapies.
鉴于部分二尖瓣脱垂(MVP)患者存在严重二尖瓣反流、心力衰竭或心源性猝死的不良预后,确定高危患者至关重要。几十年来,研究人员首次有了先进的成像技术、新型组学方法,以及使用基于网络的平台进行大规模合作的潜力,从而可以快速推进 MVP 领域的发现。美国国立心肺血液研究所(National Heart, Lung, and Blood Institute)最近启动了一个基于网络研讨会的工作组,以确定 MVP 治疗方面的当代研究机会。本报告总结了工作组关注的 MVP 治疗的 3 个具体领域:1)改善退行性二尖瓣反流及相关左心室收缩功能障碍的管理;2)预防 MVP 中心源性猝死;3)通过遗传研究以及小型和大型动物模型来了解 MVP 的发病机制和进展,从而有可能开发出医学治疗方法。
