Key result
Cauliflower-shaped left atrial appendage (OR 10.177; 95% CI 2.458-42.140) and increased end-diastolic volume (OR 1.556) independently predicted thromboembolic events in NVAF patients.
Why the study?
Do left atrial appendage parameters assessed by real-time 3D transesophageal echocardiography predict thromboembolic risk in patients with nonvalvular atrial fibrillation?
Observational (n=444)

May aid thromboembolic risk stratification in NVAF; leaves open prospective validation before clinical use.
Chen et al. (2017) conducted an observational in Nonvalvular atrial fibrillation (n=444). Left atrial appendage cauliflower shape and increased end-diastolic volume vs. Non-cauliflower shape and lower end-diastolic volume was evaluated on Thromboembolic events (OR 10.177, 95% CI 2.458-42.140, p=0.001). Cauliflower-shaped left atrial appendage (OR 10.177; 95% CI 2.458-42.140) and increased end-diastolic volume (OR 1.556) independently predicted thromboembolic events in NVAF patients.
