The quantitative assessment of mitral regurgitation (MR) by echocardiography has limitations. Cardiac magnetic resonance (CMR) imaging has an emerging role in the quantitation of MR, and preliminary studies indicate that CMR assessment may more accurately quantify MR and better correlate with postsurgical left ventricular reverse remodeling. The authors here report a case of MR in which multimodality imaging with CMR and transesophageal echocardiography was crucial in accurately diagnosing the severity of MR when transthoracic and provocative supine bike echocardiography underestimated the degree of MR in a unique variant known as "garden-hose" MR.
超声心动图对二尖瓣反流（MR）的定量评估存在局限性。心脏磁共振（CMR）成像在 MR 的定量评估中具有新兴作用，初步研究表明 CMR 评估可能更准确地定量 MR，并与术后左心室逆重构更好地相关。作者在此报告了一例 MR 病例，其中 CMR 和经食管超声心动图的多模态成像对于准确诊断 MR 的严重程度至关重要，当经胸和激发性仰卧自行车超声心动图低估了一种称为“花园 hose”MR 的独特变异型的 MR 程度时。
