Intraoperative transesophageal echocardiography (iTEE) is widely accepted and routinely used during heart valve surgery. However, the impact of iTEE among patients undergoing coronary artery bypass grafting (CABG) is less well documented. In this study, we aim to define the impact of iTEE in patients undergoing myocardial revascularization for severe coronary artery disease.
We analyzed clinical data and preoperative and intraoperative echocardiograms of all adults who underwent on pump coronary bypass and iTEE between January 2008 and December 2008.
521 patients (mean age 69±14 years) were studied. New prebypass findings were obtained in 82 (15.7%) patients: in 62 (11.9%) of these patients, this information changed the surgical plan. New postbypass findings were obtained in 8 patients (1.5%) and the surgical plan was altered in 4 patients (0.7%).
Overall new findings were obtained in 90 patients (17.2%) and the surgical plan was altered in 66 patients (12.6%). These data support the routine use of iTEE among patients undergoing surgical myocardial revascularization.
术中经食管超声心动图（iTEE）在心脏瓣膜手术中已被广泛接受并常规使用。然而，iTEE在冠状动脉旁路移植术（CABG）患者中的影响记录较少。在本研究中，我们旨在确定iTEE对严重冠状动脉疾病患者进行心肌血运重建的影响。
我们分析了2008年1月至2008年12月期间所有接受体外循环冠状动脉搭桥术和iTEE的成年人的临床数据以及术前和术中超声心动图。
共研究了521例患者（平均年龄69±14岁）。82例（15.7%）患者在搭桥术前有新发现：其中62例（11.9%）患者的这些信息改变了手术计划。8例（1.5%）患者在搭桥术后有新发现，4例（0.7%）患者的手术计划被改变。
总体而言，90例患者（17.2%）有新发现，66例患者（12.6%）的手术计划被改变。这些数据支持在进行手术心肌血运重建的患者中常规使用iTEE。
