Abstract：
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.
摘要：
通过超声心动图定量评估二尖瓣返流（MR）具有局限性。心脏磁共振（CMR）成像在MR的定量中具有新兴的作用，初步研究表明，CMR评估可以更准确地量化MR，并与术后左心室逆转重构更好地相关。作者在此报告了一例MR，其中CMR和经食道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，经胸和挑衅性仰卧位自行车超声心动图低估了MR的程度，这种独特的变体称为“花园软管”MR。
