Key result
Higher LAESVI linked to ~24% increased LAA thrombus risk in AF.
Why the study?
Assessing thromboembolic risk in atrial fibrillation patients is crucial, and left atrial volume is a promising predictor of cardiac thrombosis that requires evaluation.
Does increased left atrial volume predict left atrial appendage thrombus in patients with atrial fibrillation?
Population
73 patients with atrial fibrillation
Comparison

Increased left atrial volume measured by cardiac CT is a significant predictor of left atrial appendage thrombus in patients with atrial fibrillation.
Observational (n=73)
Does increased left atrial volume predict left atrial appendage thrombus in patients with atrial fibrillation?
Odds Ratio: 1.24 (95% CI 1.03–1.5)
p-value: p=0.02
Increased left atrial volume measured by cardiac CT is a significant predictor of left atrial appendage thrombus in patients with atrial fibrillation.
Osawa et al. (2020) conducted an observational in atrial fibrillation (n=73). Left atrial end-systolic volume index (per 10 mL/m2 increase) was evaluated on Left atrial appendage thrombus (OR 1.24, 95% CI 1.03-1.50, p=0.02). Increased left atrial end-systolic volume index was significantly associated with left atrial appendage thrombus in patients with atrial fibrillation (OR 1.24; 95% CI 1.03-1.50; P=0.02).
