In the local anesthesia state, left atrial appendage closure cannot be accomplished under the real-time guidance of conventional transesophageal echocardiography because it induces significant discomfort for the patient. Transnasal transesophageal echocardiography can be well-tolerated by patients without general anesthesia for a prolonged examination time and can acquire excellent images. This case report describes the initially successful percutaneous left atrial appendage closure under the real-time guidance of transnasal transesophageal echocardiography without general anesthesia in a nonvalvular atrial fibrillation patient. The device covered the ostium of the left atrial appendage properly and stably, and there was no significant residual peridevice leak or device-associated thrombus postoperatively.
在局部麻醉状态下，由于常规经食管超声心动图会引起患者明显不适，因此无法实时指导左心耳封堵术。经鼻经食管超声心动图无需全身麻醉即可耐受，且可进行长时间检查，并能获得优质的图像。本病例报告描述了在非瓣膜性心房颤动患者中，首次在实时经鼻经食管超声心动图引导下，无需全身麻醉成功进行经皮左心耳封堵术。该器械适当地、稳定地覆盖左心耳口，术后无明显残余器械周围漏或器械相关血栓。
