Key result
Right atrial fibrillation was associated with a smaller left atrial volume (64.5 vs 81.3 mL/m2; P=0.04) and less epicardial adipose tissue compared to left atrial fibrillation.
Why the study?
What are the differences in structural characteristics and epicardial adipose tissue volume between patients with right atrial fibrillation and left atrial fibrillation?
Population
40 patients with atrial fibrillation
Comparison
Right atrial fibrillation (RAF) vs Left atrial fibrillation (LAF)
Design
Cross-sectional

Smaller LA volume distinguishes RAF from LAF; hypothesis-generating for biatrial remodeling patterns in AF subtypes.

Absolute Event Rate: 64.5% vs 81.3%
p-value: p=0.04
Right atrial fibrillation is structurally characterized by predominant right atrial appendage enlargement, a smaller left atrium, and less epicardial adipose tissue surrounding the atria compared to left atrial fibrillation.
Hasebe et al. (2017) conducted an observational in Atrial fibrillation (n=40). Right atrial fibrillation vs. Left atrial fibrillation was evaluated on Left atrial (LA) volume (mL/m2) (p=0.04). Right atrial fibrillation was associated with a smaller left atrial volume (64.5 vs 81.3 mL/m2; P=0.04) and less epicardial adipose tissue compared to left atrial fibrillation.
