The mean value of the Koch's triangle area was 151.5 ± 55.8 mm2. The 95th percentile of triangle's height (the distance from the apex to the coronary sinus) was 21.8 mm. Conclusion: Mean values and proportions of triangle's sides and angles were presented. Koch's triangle showed considerable individual variations in size.

The triangle of Koch is defined by the following structures within the right atrium: (1) The ostium of the coronary sinus, posteriorly; (2) the anterior portion of the tricuspid valve annulus; and (3) the tendon of Todaro (a tendinous structure connecting the valve of the inferior vena cava ostium to the central fibrous body), posteriorly.

Koch's triangle, named after the German pathologist Walter Koch, [1] is an anatomical area located in the superficial paraseptal endocardium of the right atrium, which its boundaries are the coronary sinus orifice, tendon of Todaro, and septal leaflet of the right atrioventricular valve. [2]

Triangle of Koch All About Cardiovascular System and Disorders

This anatomic region is also commonly referred to as the triangle of Koch. The sinoatrial nodal artery supplies blood to the sinoatrial node, it branches off the right coronary artery in 60% of cases, whereas in 40% of cases, it comes from the left circumflex coronary artery. The blood supply to the AV node is from the AV nodal branch of the.

Triangle of Koch is situated on the right atrial aspect of the inter-atrial septum. It is bounded by the septal tricuspid leaflet, tendon of Todaro and the coronary sinus. The atrioventricular node is located at the apex of this triangle [1]. The initial description of the triangle was by Walter Koch in 1909 [2].

Relationship to the conduction system

This anatomic region is also commonly referred to as the triangle of Koch. The blood supply to the AV node is from the AV nodal branch of the right coronary artery (90%) or the left circumflex artery (10%) depending on the right or left dominant blood supply to the heart. The first septal perforator of the left anterior descending artery also.

The Legendary Triangle of Koch

Introduction: There is growing use of the Todaro tendon and triangle of Koch as anatomic icons for invasive cardiac electrophysiologists. Reasons exist to doubt this validity. Methods and results: Histologic sections were prepared from 96 anatomically normal human hearts. The study area extended from the crista supraventricularis to the eustachian valve and included the AV node and His bundle.

The coronary sinus originates from the confluence of the oblique vein (of Marshall) of left atrium and the great cardiac vein, and receives the small and middle cardiac veins, and the posterior vein of the left ventricle as tributaries. This article will discuss the anatomy and function of the coronary sinus. Contents Anatomy and course
