Abstract:
Objective To explore the value of echocardiography in percutaneous left atrial appendage (LAA)closure for stroke prevention in patients with nonvalvular atrial fibrillation during procedure and for short-term follow-up.Methods Twenty patients were enrolled to undergo percutaneous LAA closure with the LAmbre device.Rheumatic valvular diseases were excluded by transthoracic echocardiography (TTE) and transesophageal echocardiography(TEE)before the closure procedure.TEE was performed during the procedure for the trans-septal puncture and the release of the closure device.Combined TEE with angiographic measurements,guidance for the optimal device size was provided.The closure effect and procedure-related complications were observed immediately by TEE and also evaluated by TTE at 1-day and 1-month follow-up.Results All patients underwent LAA occlusion successfully.TEE color Doppler evaluation have shown nine patients with complete closure immediately,one with a ≤ 1 mm residual LAA leak,and ten with a 1 -3 mm jet.There were no other complications during the procedure.One day after the closure,small pericardial effusions were observed for three patients while two of the three were free of the pericardial effusion at the 1-month follow-up.During the short-term follow-up,no damage was found at any anatomical structures near LAA due to the closure process,and there was no significant difference of cardiac function before and after the procedure.Conclusions With the guidance of TEE,the successful rate of percutaneous LAA closure procedure was preferable and the occurrence rate of compliance was acceptable. And TTE played an important role in patients'short-term follow-up.
