Abstract:
Objective To investigate the feasibility and safety of modified percutaneous left atrial appendage occlusion (PLAAO) under transthoracic echocardiographic (TTE) guidance without general anesthesia instead of transesophageal echocardiographic guidance.Methods A total of 14 patients who met the inclusion criteria underwent modified PLAAO guided by TTE instead of TEE without general anesthesia.Regular clinical follow-up observations of PLAAO-related major adverse events were done in the perioperative period.Results All patients were successfully implanted with left atrial appendage occluder device (Watchman) without device-related serious complications.Immediately occlusion success rate was 100％.No major adverse events occurred during hospitalization and follow-up.The mean operation time was 108 ± 22 min(range 75-150 min)and the mean radiation exposure time was 15.8 ± 7.6 min(range 8-32 min).Conclusion Modified PLAAO guided by TTE instead of TEE without general anesthesia may be safe and effective.This method simplifies the operation process and is favorable for PLAAO application.But this modified PLAAO is still needed to be validated in more patients.
