Evaluation of left atrial volume and function using single-beat real-time three-dimensional echocardiography in atrial fibrillation patients.

ABSTRACT:

Background

This study was aimed to evaluate the feasibility and accuracy of real-time three-dimensional echocardiography (RT-3DE) measurement of left atrial (LA) volume and function in comparison with two-dimensional echocardiography (2DE) measurements in atrial fibrillation (AF) patients.

Methods

A total of 50 pairs of AF patients and healthy controls were enrolled in this study. Indexed LA end-diastole volume (ILAEDV) and indexed LA end-systolic volume (ILAESV), as well as LA function indices such as segmental LA ejection fraction (LAEF), were assessed using 2DE Simpson's method and the RT-3DE method.

Results

The images showed that regional LA volume-time curves and LAEF were disordered in AF patients. ILAEDV and ILAESV were markedly increased and global LAEF was si
