The efficacy of trans-esophageal echocardiography in treatment of nonvalvular atrial fibrillation with left atrial appendage occlusion.
2018
OBJECTIVE: To investigate the efficacy of transesophageal echocardiography (TEE) in the treatment of nonvalvular atrial fibrillation with left atrial appendage (LAA) occlusion. PATIENTS AND METHODS: Forty-nine patients with nonvalvular atrial fibrillation were selected from January 2015 to December 2015 to serve as control group, and 49 patients with nonvalvular atrial fibrillation were selected from January 2016 to December 2016 to serve as observation group. Patients in both groups were treated with LAA occlusion. After surgery, patients in control group received 2D-transesophageal echocardiography (2D-TEE), while patients in observation group received 3D-TEE. LAA diameter, maximum depth, postoperative parameters, and postoperative complications were compared between two groups. RESULTS: The maximum LAA diameter can be measured from different angles in control group, and maximum depth cannot be measured in control group. No significant differences in maximum LAA diameter and maximum depth were found between two groups from different angles (p<0.05). No significant difference in left ventricular end diastolic diameter (LVEDd), left atrial diameter (LA-d), left ventricular ejection fraction (LVEF), mitral regurgitation volume (MV Reg V), E peak and pulmonary vein diastolic flow velocity (PVd) were found between those two groups (p<0.05). The overall occurrence of postoperative complications in observation group and control group were 0.00% and 12.24%, respectively, significant difference was found between those two groups (p<0.05). CONCLUSIONS: Compared with 2D-TEE, the application of 3D-TEE in treatment of nonvalvular atrial fibrillation with left atrial appendage occlusion is more conducive to the selection of the size of the reservoir, and can reduce the occurrence of postoperative complications.
