Application of computed tomographic angiography and echocardiography in predicting left atrial appendage thrombosis in patients with non-valvular atrial fibrillation
CONCLUSIONS: Both CTA and RT-3D-TEE had high predictive values for LAA thrombosis in atrial fibrillation patients.PMID:36383152 | DOI:10.5830/CVJA-2022-052

Left Atrial Appendage Shape Linked to Stroke Risk in AF Left Atrial Appendage Shape Linked to Stroke Risk in AF
With names like cauliflower and chicken wing, one type of LAA was associated with a more than 2.5-fold higher risk of stroke or transient ischemic attack while another with a 68% decreased risk.First Look

Left atrial appendage morphology and cardiac function in patients with sinus rhythm
ConclusionsThese findings suggest that impaired LA and LAA functions are related to changes of the LAA in patients with sinus rhythm.

Procedural success and intra ‐hospital outcome related to left atrial appendage morphology in patients that receive an interventional left atrial appendage closure
ConclusionsIrrespective of the varying morphological presentation of the LAA, the procedural success rates, interventional characteristics, and safety events did not significantly differ among patients receiving an interventional LAA closure.

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.

Correlation between left atrial appendage morphology and flow velocity in patients with paroxysmal atrial fibrillation
Conclusion LAA morphology is a significant determinant of LAAFV, suggesting an underlying mechanism for the association between LAA morphology and embolic events.

Cardiogenic Stroke despite Low CHA2DS2‐VASc Score: Assessing Stroke risK by Left Atrial Appendage Anatomy (ASK LAA)
Conclusion: A higher LAA takeoff is associated with a tachycardia‐mediated thrombogenic flow and an increased thromboembolic risk. These findings may have implications for anticoagulation management of AF patients with low CHA2DS2‐VASc scores and higher LAA takeoff.This article is protected by copyright. All rights reserved

Safety and effectiveness of compassionate use of LARIAT® device for epicardial ligation of anatomically complex left atrial appendages
Conclusions Despite a high preclusion rate, percutaneous LAA ligation may be safely and effectively performed on compassionate grounds using the first-generation LARIAT® device with surgical standby in patients with large and complex LAA.

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...

Cruciferous LAA predicts stroke in otherwise-low-risk AF patients
Of four left-atrial-appendage morphology types by CT imaging, which had colorful names like "cauliflower" and "chicken wing," one independently predicted stroke in patients with atrial fibrillation but a low CHADS2 score.
