The LAA is a muscular pouch connected to the left atrium (LA). Epub 2015 May 5. LAA morphology has been classified into 4 types: chicken wing, cauliflower, windsock, and cactus. The complex LAA is an independent risk factor for LAA thrombosis in NVAF patients. Korhonen M, Muuronen A, Arponen O, et al. Chicken Wing LAA was identified by an obvious bend <110° in the proximal or middle part of the dominate lobe or folding back of the LAA anatomy on itself at some distance from the ostium. HHS Types of Left Atrial Appendage Closure. It has been suggested in a few studies that certain types of LAA morphology are at heightened risk for thromboembolism in AF patients. Whether LAA morphology is associated with increased stroke/TIA risk is controversial and, if it does, which morphological type most predisposes to thrombus formation. It has developmental, ultrastructural, and physiological characteristics distinct from the left atrium proper. Left atrial appendage occlusion is experience-dependent, technical-demanding, and is highly associated with risks of occlusion-related complications, especially in LAAs with complex morphology. LAA was classified into four morphology types (Cactus, ChickenWing, WindSock, CauliFlower) modified with a quantitative qualifier.

Among patients with atrial fibrillation (A-fib), the particular morphology of the left atrial appendage (LAA)—the source of most thromboemboli—appears to affect stroke risk, according to a study published in the August 7, 2012, issue of the Journal of the American College of Cardiology. The left atrial appendage (LAA) remains a medical enigma; the morphology of this structure is poorly unders- tood. The left atrial appendage (LAA) (also known as left auricle ) is a pouch-like projection from the main body of the left atrium, which lies in the atrioventricular sulcus in close proximity to the left circumflex artery, the left phrenic nerve, and the left pulmonary veins. Introduction. Epub 2014 May 22. It is unclear what function, if any, the LAA performs. We aimed to systematically anlyze all the 2 More than 90% of ischemic stroke thrombus in patients with non‐valvular atrial fibrillation (NVAF) was derived from the left atrial appendage (LAA).

Background: The left atrial appendage (LAA) is the main source of thrombus in atrial fibrillation, and there is an association between non-chicken wing (NCW) LAA morphology and stroke. Left atrial appendage volume increased in more than half of patients with cryptogenic stroke. Prevalence of LAA morphologies among the three study groups. Cactus has a dominant central lobe, one or more secondary lobes, and total length less than 4 cm. Whether LAA morphology is associated with increased stroke/TIA risk is controversial and, if it does, which morphological type most predisposes to thrombus formation. Generally, this disease occurs with a frequency of 8% in the Western population; in patients over 65 years old, it is as high as 20%.

A systematic review of MEDLINE, Cochrane Library, and Embase for studies that used computed tomography, tridimensional transesophageal echocardiography, and cardiac magnetic resonance imaging to categorize the LAA morphologies with assessment of TE prevalence. Do left atrial appendage morphology and function help predict thromboembolic risk in atrial fibrillation? The LAA is a muscular pouch connected to the left atrium (LA). Others could gain regulatory approval in the future. TE risk was lower in chicken wing morphology than in non-chicken wing morphology (OR 0.46; 95% CI 0.36-0.58). Complex Left Atrial Appendage Morphology Is an Independent Risk Factor for Cryptogenic Ischemic Stroke. Atrial fibrillation (AF) is the most common clinically important cardiac arrhythmia, occurring in approximately 0.4% to 1% of the general population and increasing with age to >8% in those >80 years of age. Patients with chicken wing LAA morphology are less likely to develop TE than patients with non-chicken wing morphology. Kong B, Liu Y, Hu H, Wang L, Fan Y, Mei Y, Liu W, Liao J, Liu D, Xing D, Huang H. Nat Clin Pract Cardiovasc Med. Atrial fibrillation (AF) carries out a 5-fold increase in stroke risk, related to embolization of thrombi clotting in left atrium (LA). Whether LAA morphology is associated with increased stroke/TIA risk is controversial and, if it does, which morphological type most predisposes to thrombus formation. 4, 5 A previous study has shown that a mobile, ball-type thrombus is an important risk factor for cerebral/arterial embolism 6 and a recent study reported that transcatheter LAA closure is safe and feasible. “Hook” is an arched structure that is symmetrical at its midpoint; B.
