The rapid search for suitable tricuspid transcatheter devices has ignited renewed enthusiasm in accurate characterization of tricuspid valve disease. Cardiovascular magnetic resonance (CMR), traditionally used as the gold standard in assessment for right ventricular size and function, has recently seen its use expanded to assess both the structure and function of the tricuspid apparatus. This review will highlight the role of CMR in tricuspid valve disease and compare it with other commonly used imaging modalities.
Dynamic anatomical assessment of the tricuspid apparatus, in combination with accurate leaflet identification, is possible with CMR. Tricuspid regurgitation volume and fraction are derived through an indirect volumetric method, and therefore, able to overcome many traditional hurdles involved with valve regurgitation quantitation. Adverse right heart prognostic factors in tricuspid valve disease, such as right heart volumes, function, and tissue characterization, are optimally assessed using CMR.
Cardiovascular magnetic resonance is a powerful modality that should be harnessed in order to obtain a multifaceted assessment of tricuspid valve structure, function, and the effects of valve disease on right heart remodeling.
对三尖瓣经导管治疗装置的快速探索重新燃起了人们对三尖瓣疾病准确评估的热情。心血管磁共振（CMR）传统上被用作评估右心室大小和功能的金标准，最近其在评估三尖瓣装置的结构和功能方面的应用也得到了扩展。本文将重点介绍 CMR 在三尖瓣疾病中的作用，并将其与其他常用的成像方式进行比较。
CMR 可实现三尖瓣装置的动态解剖评估，并结合准确的瓣叶识别。三尖瓣反流容积和分数通过间接容积法得出，因此能够克服瓣膜反流定量分析中许多传统的障碍。CMR 可以最佳地评估三尖瓣疾病中的不良右心预后因素，如右心容积、功能和组织特征。
心血管磁共振是一种强大的成像方式，应该加以利用，以获得三尖瓣结构、功能以及瓣膜疾病对右心重构影响的多方面评估。
