To compare transthoracic and transesophageal echocardiography in the clinical assessment of left-sided valvular regurgitation, 118 patients who underwent both transesophageal and transthoracic echocardiographic studies within a 24-hour period were included in this study. Presence or absence of aortic regurgitation was identified concordantly by both techniques in 93 patients (79%). Complete agreement between both techniques was found in 88 patients (75%). Presence or absence of mitral regurgitation was identified concordantly by both techniques in 89 patients (75%). Complete agreement in grade was found in only 74 patients (63%). Twenty-nine patients (25%) had mitral regurgitation detected by transesophageal echocardiography, but not by transthoracic echocardiography. Four of these patients (14%) had significant (2 to 3+) mitral regurgitation. Differences between transesophageal and transthoracic echocardiography do not appear to be clinically important in patients with aortic regurgitation. In mitral regurgitation, significant differences exist between these 2 techniques, with transesophageal echocardiography being much more sensitive.
为比较经胸超声心动图和经食管超声心动图在左侧瓣膜反流临床评估中的作用，本研究纳入了118例在24小时内同时接受经食管和经胸超声心动图检查的患者。两种技术在93例患者（79%）中对主动脉瓣反流的有无判断一致。两种技术完全一致的有88例患者（75%）。两种技术在89例患者（75%）中对二尖瓣反流的有无判断一致。仅在74例患者（63%）中反流程度判断完全一致。29例患者（25%）经食管超声心动图检测到二尖瓣反流，但经胸超声心动图未检测到。其中4例患者（14%）有显著（2至3+）二尖瓣反流。经食管和经胸超声心动图之间的差异在主动脉瓣反流患者中似乎不具有临床重要性。在二尖瓣反流中，这两种技术存在显著差异，经食管超声心动图更为敏感。
