Key result
3D echocardiography revealed significantly higher left atrial volume and pulmonary vein structure parameters in patients with atrial fibrillation compared to healthy controls.
Why the study?
The clinical value of 3D echocardiography in evaluating changes in left atrial volume and pulmonary vein structure in patients with AF remained to be explored.
Does 3D echocardiography identify differences in left atrial volume and pulmonary vein structure between patients with atrial fibrillation and healthy people?

Does 3D echocardiography identify differences in left atrial volume and pulmonary vein structure between patients with atrial fibrillation and healthy people?
3D echocardiography is a valuable imaging modality for evaluating structural changes in the left atrium and pulmonary veins in patients with atrial fibrillation.
OBJECTIVE: To explore the clinical value of 3D Echocardiography (3DE) in evaluating the changes of left atrial volume and pulmonary vein structure in patients with Atrial Fibrillation (AF). METHODS: Clinical data were collected from 54 AF patients. Left Atrial Anteroposterior Diameter (LADap), Left Atrial left and right Diameter (LADml), and Left Atrial upper and lower Diameter (LADsi) were measured; the maximum Left Atrial Volume (LAVmax), minimum Left Atrial Volume (LAVmin), left atrial presystolic volume (LAVpre), and Cross-Sectional Area (CSA) of each pulmonary vein were analyzed. Passive Ejection Fraction (LAPEF) was calculated. The differences in left atrial volume and pulmonary vein structure between patients with AF and healthy people were compared, and the correlation between the indexes was analyzed. The diagnostic value of the above indicators for AF patients was analyzed. RESULTS: LADap, LADml, LADsi, LAVmax, LAVmin, LAVpre, LAPEF, LSPV CSA, LIPV CSA, RSPV CSA, and RIPV CSA of AF patients were significantly higher. There was a significant positive correlation between left atrial diameter and pulmonary vein structure. There was a significant positive correlation between left atrial volume and pulmonary vein structure. There was a negative correlation between LAPEF and pulmonary vein structure. LADap, LADml, LADsi, LAVmax, LAVmin, LAVpre, LAPEF, LSPV CSA, LIPV CSA, RSPV CSA, and RIPV CSA had a diagnostic value for AF patients. CONCLUSION: 3DE is applicable for evaluating left atrial volume and pulmonary vein structure in patients with AF.
