Mitral regurgitation is one of the more common forms of valvular heart disease. Given the expansion of therapies for structural heart disease, new therapies for mitral regurgitation are emerging. An accurate description and classification of mitral disease is important to understand pathology and provide recommendations for therapy. Areas covered: In the modern evaluation of mitral regurgitation, 3-dimensional echocardiography (3DE) and cardiac magnetic resonance imaging (CMR) play important roles which overcome the prior limitations of 2-dimensional echocardiography. Specifically, an advanced evaluation with these techniques allows accurate characterization of the anatomic etiology of mitral regurgitation and quantification of severity. Furthermore, the role of 3DE during intraprocedural guidance, 'interventional echocardiography,' is expanding. Expert commentary: In our review, we demonstrate a complete diagnostic evaluation of mitral valve dysfunction by 3DE and CMR and describe current implications for invasive therapy and procedural guidance.
二尖瓣反流是较为常见的心脏瓣膜病形式之一。鉴于结构性心脏病治疗方法的不断扩展，二尖瓣反流的新疗法也不断涌现。准确描述和分类二尖瓣疾病对于理解病理状况并提供治疗建议至关重要。涵盖领域：在二尖瓣反流的现代评估中，三维超声心动图（3DE）和心脏磁共振成像（CMR）发挥着重要作用，克服了二维超声心动图先前的局限性。具体而言，运用这些技术进行的高级评估能够准确确定二尖瓣反流的解剖学病因并对严重程度进行量化。此外，3DE在术中引导（“介入性超声心动图”）方面的作用正在不断扩大。专家评论：在我们的综述中，我们展示了通过3DE和CMR对二尖瓣功能障碍进行的全面诊断评估，并描述了其对侵入性治疗和手术引导的当前影响。
