Results of 34 transesophageal (TEE) studies in patients with suspected aortic prosthetic dysfunction were compared with transthoracic echocardiographic (TTE) results and to anatomic findings. Mass lesions noted at surgery (autopsy) were correctly described in 93% by TEE versus 43% by TTE. Abscesses were detected in 88% by TEE versus 18% by TTE. Bioprosthetic degeneration was visualized in 88% versus 38% and prosthetic obstruction correctly identified in 75% versus 50% by TEE and TTE, respectively. Anatomic aortic regurgitant lesions were identified in 96% by TEE versus 77% by TTE, whereas the correct origin was detected in 88% of cases by TEE versus 54% of cases by TTE. TEE provides valuable additional information on morphologic conditions and flow pathology in aortic valve prostheses.
对34例疑似主动脉人工瓣膜功能障碍患者的经食管超声心动图（TEE）检查结果与经胸超声心动图（TTE）结果及解剖学发现进行了比较。手术（尸检）时发现的肿块病变，TEE正确描述的比例为93%，而TTE为43%。TEE检测出脓肿的比例为88%，TTE为18%。生物瓣退变的可视化率，TEE为88%，TTE为38%；人工瓣膜梗阻的正确识别率，TEE为75%，TTE为50%。解剖学上的主动脉反流病变，TEE识别率为96%，TTE为77%；而TEE在88%的病例中检测到正确的起源，TTE为54%。TEE可提供有关主动脉瓣人工瓣膜形态状况和血流病理学的有价值的额外信息。
