Anatomy of the left atrial appendage for the interventional cardiologist.
Gonzalez-Casal D, Datino T, Soto N, González-Panizo J, Sánchez-Quintana D, Macias Y, Cabrera JÁ. Gonzalez-Casal D, et al. Herzschrittmacherther Elektrophysiol. 2022 Jun;33(2):195-202. doi: 10.1007/s00399-022-00866-8. Epub 2022 May 23. Herzschrittmacherther Elektrophysiol. 2022. PMID: 35606533 Review. English.
Exact knowledge of the anatomy of the left atrial appendage (LAA) is crucial for LAA isolation by catheter ablation and for interventional LAA occlusion in patients with atrial fibrillation. This review outlines the current anatomical understanding of LAA morphology from o …

Developmental patterning of the myocardium.
Sedmera D, Pexieder T, Vuillemin M, Thompson RP, Anderson RH. Sedmera D, et al. Anat Rec. 2000 Apr 1;258(4):319-37. doi: 10.1002/(SICI)1097-0185(20000401)258:4<319::AID-AR1>3.0.CO;2-O. Anat Rec. 2000. PMID: 10737851 Free article. Review.
A similar process can be charted in the atrial myocardium, where the luminal trabeculations become the pectinate muscles. Their extent then provides the best guide for distinguishing intrinsically the morphologically right from the left atrium. ...Desp …

Gross structure of the atriums: more than an anatomic curiosity?
Ho SY, Anderson RH, Sánchez-Quintana D. Ho SY, et al. Pacing Clin Electrophysiol. 2002 Mar;25(3):342-50. doi: 10.1046/j.1460-9592.2002.00342.x. Pacing Clin Electrophysiol. 2002. PMID: 11990664 Review.
The right atrium contains prominent muscular bundles and an extensive array of pectinate muscles. The distal ramifications of the terminal crest lead to the "flutter" isthmus. By contrast, the left atrium has relatively smooth walls. The atrial …

The importance of atrial structure and fibers.
Ho SY, Sánchez-Quintana D. Ho SY, et al. Clin Anat. 2009 Jan;22(1):52-63. doi: 10.1002/ca.20634. Clin Anat. 2009. PMID: 18470938 Review.
These extend almost perpendicularly from the terminal crest. The left atrium has relatively smooth walls and a small tubular-shaped appendage. The myofibers show changes in orientations when traced through the thickness of the walls. ...Apart from Bachmann's bundle, …

Surgical and Electrical Anatomy of the Inter-Nodal and Intra-Atrial Conduction System in the Heart.
Seo JW, Kim JS, Cha MJ, Yoon JK, Kim MJ, Tsao HM, Lee CH, Oh S. Seo JW, et al. J Chest Surg. 2022 Oct 5;55(5):364-377. doi: 10.5090/jcs.22.030. Epub 2022 Jul 20. J Chest Surg. 2022. PMID: 35851043 Free PMC article. Review.
The posterior inter-nodal route (#3) is at the terminal crest and gives rise to many branches at the pectinate muscles of the right atrium and then approaches the posterior atrioventricular node after joining with the vestibular branch of route #1. The branch …

"Form follows function": the developmental morphology of the cardiac atria.
Neradilova C, Gregorovicova M, Kovanda J, Kvasilova A, Melenovsky V, Nanka O, Sedmera D. Neradilova C, et al. Physiol Res. 2024 Dec 31;73(S3):S697-S714. doi: 10.33549/physiolres.935503. Physiol Res. 2024. PMID: 39808172 Free PMC article. Review.
Although the heart atria have a lesser functional importance than the ventricles, atria play an important role in the pathophysiology of heart failure and supraventricular arrhythmias, particularly atrial fibrillation. ...Key words Morphology of atrial …

The muscular network of the sheep right atrium and frequency-dependent breakdown of wave propagation.
Berenfeld O, Zaitsev AV. Berenfeld O, et al. Anat Rec A Discov Mol Cell Evol Biol. 2004 Oct;280(2):1053-61. doi: 10.1002/ar.a.20106. Anat Rec A Discov Mol Cell Evol Biol. 2004. PMID: 15372488 Free article. Review.
As AF results in some cases from stable sources in the left atrium (LA) with fibrillatory conduction toward the RA, we hypothesize that periodic input to the RA at an exceedingly high frequency results in disorganized wave propagation associated with the complex str …

Left atrial appendage closure for prevention of cardioembolic events.
Gloekler S, Meier B, Windecker S. Gloekler S, et al. Swiss Med Wkly. 2016 May 31;146:w14298. doi: 10.4414/smw.2016.14298. eCollection 2016. Swiss Med Wkly. 2016. PMID: 27244534 Free article. Review.
It increases with age, affecting approximately 7% of individuals age >65 years and 15-20% of octogenarians. The human left atrium has a blind sac-like remnant, called left atrial appendage (LAA). It originates from a primordial pulmonary vein. Due to its c …

The surgical anatomy of hearts with isomeric atrial appendages-implications for surgical management.
Spicer DE, Chowdhury UK, Anderson RH, Pandey NN, Sankhyan LK, George N, Goja S, Malik V. Spicer DE, et al. Eur J Cardiothorac Surg. 2022 Jun 15;62(1):ezac139. doi: 10.1093/ejcts/ezac139. Eur J Cardiothorac Surg. 2022. PMID: 35234855 Review.
In all instances, this was made possible by using the criterion of the extent of the pectinate muscles within the appendages as judged relative to the atrial vestibules. Segregation on this basis, which correlated excellently with the bronchial arrangement, sets the …

Atrial structure and fibres: morphologic bases of atrial conduction.
Ho SY, Anderson RH, Sánchez-Quintana D. Ho SY, et al. Cardiovasc Res. 2002 May;54(2):325-36. doi: 10.1016/s0008-6363(02)00226-2. Cardiovasc Res. 2002. PMID: 12062338 Review.
Secondly, we discuss the general arrangement of myocardial fibres with respect to gross topography in the normal human heart. The right atrium is dominated by an extensive array of pectinate muscles within the extensive appendage, whereas the left …
