Title
Evaluation of left atrial volume and function using single-beat real-time three-dimensional echocardiography in atrial fibrillation patients.
Abstract
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.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.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 significantly decreased in AF patients compared with those in healthy controls (P < 0.01). No significant differences were found in ILAEDV, ILAESV, and LAEF levels as determined by the RT-3DE method or 2DE Simpson's method. Bland-Altman analysis showed that the two methods agreed well for measuring ILAEDV, ILAESV, and segmental LAEF.The RT-3DE method may be a feasible and accurate method for evaluating LA volume and function of AF patients in clinical practice.
