It has developmental, ultrastructural, and physiological characteristics distinct from the left atrium proper. Eight studies with 2596 patients were included. The left atrial appendage (LAA) is derived from the left wall of the primary atrium, which forms during the fourth week of embryonic development. 2017 Oct;34(10):2274-2294. doi: 10.1007/s12325-017-0616-6. Type 1 (Cactus) (n = 278) Type 2 (Chicken Wing) (n = 451) Type 3 (Windsock) (n = 179) Type 4 (Cauliflower) (n = 24) p Value Fig 2. Left atrial appendage volume increased in more than half of patients with cryptogenic stroke. Please enable it to take advantage of the complete set of features! TE risk was lower in chicken wing morphology than in non-chicken wing morphology (OR 0.46; 95% CI 0.36-0.58). Korhonen M, Muuronen A, Arponen O, et al. Approximately 20% of these strokes are caused by AF. National Center for Biotechnology Information, Unable to load your collection due to an error, Unable to load your delegates due to an error. Left atrial appendage morphology and risk of stroke following pulmonary vein isolation for drug-refractory atrial fibrillation in low CHA2DS2Vasc risk patients Faith R. Kelly1, Robert A. Hull2, Takor B. Arrey-Mbi2, Michael U. Williams2, Joshua S. Lee1, Ahmad M. Slim1 and Dustin M. Thomas1* Abstract 2 score, gender, and AF types in a multivariable logistic model, Chicken Wing morphology was found to be 79% less likely to have a stroke/TIA history (odd ratio: ... Stroke and Left Atrial Appendage Morphology August 7, 2012:531–8. Do left atrial appendage morphology and function help predict thromboembolic risk in atrial fibrillation? The left atrial appendage (LAA) is the typical origin for intracardiac thrombus formation. LAA morphology may be a valuable criterion in predicting TE and could affect the stratification and anticoagulation management of patients with low to intermediate TE risk. The left atrial appendage morphology and gender differences by multi-detector computed tomography in an Egyptian population Mohammed Elzeneini, Ahmed Elshazly and Ahmed El Mahmoudy Nayel* Abstract Background: The left atrial appendage (LAA) is the main source of thromboembolism in patients with non-valvular atrial fibrillation. It has been suggested that left atrial appendage (LAA) morphology independently influences TE risk in patients with nonvalvular atrial fibrillation. 3, 4 It was recently reported that LAA morphology correlates with transient ischaemic attacks (TIA) and strokes in patients with AF. The left atrial appendage (LAA) is the typical origin for intracardiac thrombus formation. It has been suggested in a few studies that certain types of LAA morphology are at heightened risk for thromboembolism in AF patients. Anselmino M, Gili S, Castagno D, Ferraris F, Matta M, Rovera C, Giustetto C, Gaita F. J Cardiovasc Med (Hagerstown). 2012 Aug 7;60(6):531-8. doi: 10.1016/j.jacc.2012.04.032. Does the left atrial appendage morphology correlate with the risk of stroke in patients with atrial fibrillation? Materials and methods: Left atrial appendages of 65 cadaveric hearts were examined. USA.gov. Heart Rhythm 2013;10:1843–9. The proportion of single-lobed LAA was significantly higher (P<0.001) in the matched stroke subgroup (55%) than the control group (6%).
