This paper describes the role of cardiovascular magnetic resonance (CMR) imaging in assessing patients with mitral valve disease. Mitral regurgitation (MR) is one of the most prevalent valvular heart diseases. It often progresses without significant symptoms, leading to left ventricular overload, dysfunction, frequent decompensated heart failure episodes, and excess mortality. Cardiovascular magnetic resonance assessment is recommended for MR when routine ultrasound imaging information is insufficient or discordant. A well-planned CMR can provide an in-depth assessment of the mitral valve apparatus, leaflet morphology, and papillary muscles. In addition, it can precisely inform the impact of MR on left atrial and ventricular remodelling. The review aims to highlight established and emerging techniques for morphological assessment, flow assessment (including regurgitation and stenosis), myocardial assessment, and haemodynamic assessment of mitral valve disease by CMR. It also proposes a simplified clinical flow chart for CMR assessment of the mitral valve.

二尖瓣疾病的心血管磁共振成像。


本文描述了心血管磁共振 （CMR） 成像在评估二尖瓣疾病患者中的作用。二尖瓣反流 （MR） 是最普遍的瓣膜性心脏病之一。它通常进展无明显症状，导致左心室超负荷、功能障碍、频繁失代偿性心力衰竭发作和超额死亡率。当常规超声影像学信息不足或不一致时，建议对 MR 进行心血管磁共振评估。精心规划的 CMR 可以对二尖瓣器官、瓣叶形态和肌进行深入评估。此外，它可以精确地告知 MR 对左心房和心室重塑的影响。本综述旨在强调用于形态学评估、血流评估 （包括反流和狭窄）、心肌评估和通过 CMR 对二尖瓣疾病进行血流动力学评估的成熟和新兴技术。它还提出了一个简化的二尖瓣 CMR 评估临床流程图。
