Left Atrial Appendage Morphology Assessment for Risk Stratification of Embolic Stroke in Patients with Atrial Fibrillation. A Meta-Analysis
Thromboembolic Event (TE) risk stratification is performed by using CHA2DS2Vasc Score. It has been suggested that left atrial appendage (LAA) morphology independently influences TE risk in patients with non-valvular atrial fibrillation (AF). The LAA morphology has been classified into four different types: Chicken Wing, Cauliflower, Windsock and Cactus.

Relationship between left atrial appendage morphology and stroke in patients with atrial fibrillation
Background: Atrial fibrillation (AF) is an important cause of stroke. Given the morbidity and mortality associated with stroke, the risk stratification of patients based on left atrial appendage (LAA) characteristics is of great interest.Objective: To explore the association between LAA morphology and LAA characteristics including the extent of trabeculations, orifice diameter, and length with prevalent stroke in a large cohort of patients with drug refractory AF who underwent AF ablation to develop mechanistic insight regarding the risk of stroke.Methods: An institutional cohort of 1063 patients referred for AF ablation f...

Anatomical characteristics of the left atrial appendage in cardiogenic stroke with low CHADS2 scores
Conclusions: The LAA anatomy might be useful for predicting strokes in patients with nonvalvular AF who have low CHADS2 scores.
