Clinical value and index analysis of transesophageal echocardiography in diagnosis of patients with atrial fibrillation

Abstract

Objective To explore the clinical value of transesophageal echocardiography in the diagnosis of patients with atrial fibrillation. Methods 60 patients with atrial fibrillation and 50 without treated at our hospital from May, 2015 to May, 2016 were selected. The LA, LV, RA, RV, EF, FS, MV, 2D-FAC, PEV, TDI-L, TDI-S, TDI-A, and SEC were determined by transesophageal echocardiography. Results The diameters of LA, LV, RA,and RV were larger in the observation group than in the control group [ (4.55±1.11) cm vs. (3.52±0.56) cm, (5.23±0.81) cm vs. (4.80±0.44) cm, (3.87±0.62) cm vs. (3.43±0.23) cm, and (2.26±0.55) cm vs. (1.97±0.36) cm ), with statistical differences (all P<0.05). The functions of left ventricular and left atrial appendage were better in the control group than in the observation group, with statistical differences (all P<0.05). Conclusions Transesophageal echocardiography can help to determine the patients’ functions of left ventricular and left atrial appendage and plays a good guiding role in clinical practice.
