| 探讨三维经食管超声心动图（3D-TEE）在经心尖入路的经导管主动脉瓣置换术（TA-TAVR）中的监测作用。方法 连续选取西京医院行TA-TAVR植入J-Valve瓣膜的患者44例，所有患者均于全麻下行3D-TEE检查，评估主动脉根部结构及瓣叶病变，引导J-Valve输送系统进入左室并释放人工瓣膜，术后即刻评价手术效果及术后并发症。结果 在3D-TEE实时监测引导下，44例患者中有42例成功植入J-Valve瓣膜，成功率95.45%。3D-TEE预测人工瓣膜与实际植入瓣膜型号的符合率为76.19%，术后即刻瓣周漏的发生率为33.33%，左室射血分数无明显变化。结论 3D-TEE可为TA-TAVR提供重要的引导作用，并即刻评价手术效果和并发症，具有重要的临床价值。 |

| Abstract: |
| Objective To investigate the monitoring effect of 3D transesophageal echocardiography in transapical transcatheter aortic valve replacement（TA-TAVR）.Methods Forty-four consecutive patients with?aortic stenosis underwent J-Valve valves replacement via the transapical route at Xijing Hospital were selected.All patients underwent 3D-TEE examination to evaluation of aortic root structure，valve lesions under 2 Preoperative TEE was applied，Guide the J-Valve delivery system into the left ventricle and release the prosthetic valve during the operation，and evaluate the effect and postoperative complications immediately after procedure.Results Under the guidance of 3D-TEE real-time monitoring，42 of 44 patients successfully implanted J-Valve，with a success rate of 95.45%.The coincidence rate between the valve model predicted by 3D-TEE and the final implanted valve model was 76.19%.The incidence of immediate postoperative perivalvular leakage was 33.33%.Compared with preoperative，there was no significant change in left ventricular ejection fraction postoperative.Conclusion Three-dimensional-TEE plays an important role in guiding TA-TAVR，and can evaluate the effect and complications immediately.It is an indispensable auxiliary means for success of TA-TAVR. |
