ABSTRACT
Objective To assess the feasibility and accuracy of transesophageal echocardiography (TEE) in screening patients,intraoperative guidance of occluder releasing and efficacy assessment in the patients of percutaneous left atrial appendage (LAA) occlusion with Watchman.Methods Ultrasonic instrument Philips iE33(proble model X7-3t) were used to measure the maximum diameter and the depth of LAA ostium in enrolled patients by TEE,and intraoperative guided puncture of interatial septum,positioning Watchman transmission system and instruction closure release under TEE,immediate evaluate the postoperative therapeutic effect and record the complications by TEE.At 45 days after implantation,patients should repeat TEE to assess the efficacy.Results Eighteen patients underwent device implantation.Seventeen patients implant successfully,except one patient can't implant device beacuse of the LAA morphologe was not suitable.There was one patient showing thrombus formation on the surface of device,one patient of LAA and the device axial angulation was 90 °.At 45 days after implantaion,16 patients were fullowed up,there were no major stroke at all.Conclusions TEE has important application value in screening of preoperative patients,intraoperative guidance of occluder releasing and efficacy assessment in the patients of percutaneous left atrial appendage occlusion with Watchman.
