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

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.

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.

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.

Impact of left atrial appendage morphology on indication and procedural outcome after interventional occlusion - results from the prospective multicenter German LAARGE registry.
CONCLUSIONS: Procedural success as well as complication rates of LAAC were not different amongst the 4 typical LAA morphologies. Only in patients with atypical LAA morphologies a lower implantation success was obvious. PMID: 29508766 [PubMed - as supplied by publisher]

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.

Morphometrical features of left atrial appendage in the AF patients subjected to left atrial appendage closure
CONCLUSIONS: Important morphometrical differences in LAA orifice have been found, which was significantly larger and more oval in patients with atrial fibrillation compared to healthy controls. Although no difference in LAA body type and size was observed; the LAA ejection fraction was significantly lower in atrial fibrillation rhythm patients.PMID:36165901 | DOI:10.5603/FM.a2022.0080
