The valve of the coronary sinus (Thebesian valve) is a semicircular fold of the lining membrane of the right atrium, at the orifice of the coronary sinus.It is situated at the base of the inferior vena cava. The valve may vary in size, or be completely absent. It may prevent the regurgitation of blood into the sinus during the contraction of the atrium Koronarsinus syns nederst i bilden (märkt coronary sinus) Koronarsinus är ett kort kärl på hjärtats posteriora del som knyter samman de tre koronarvenerna, v. cordis magna/media/parva.

  1. Atresia of coronary sinus ostium is often associated with unroofed coronary sinus, constituting a small right to left shunt. The absence of connection with the left atrium and its drainage into the left superior caval vein is a very rare entity ,. A classification of coronary sinus abnormalities was suggested in 1966 by Mantini et al , who identified four different types

  3. Objective: To investigate electrophysiological characteristics of the coronary sinus musculature and explore its role on electrical conduction between left atrium and right atrium in isolated canine heart. Method: The electrical connections between coronary sinus, left atrium and right atrium were detected by programmed stimulation delivered at coronary sinus ostium, distal coronary sinus and.
  4. The CS ostium is located between the inferior vena cava and the inferior tricuspid annulus. 3 Often times, the opening is guarded by a fold of endocardial tissue, an embryological remnant of the right sinus valve, termed the valve of the CS or Thebesian valve
  5. The coronary sinus is a collection of smaller veins that merge together to form the sinus (or large vessel), which is located along the heart's posterior (rear) surface between the left ventricle.

The coronary sinus drains into the right atrium, at the coronary sinus orifice,. Coronary sinus (sinus coronarius) The coronary sinus is a large venous structure located on the posterior aspect of the left atrium, coursing within the left atrioventricular groove.The function of the coronary sinus is to drain the venous blood from the majority of the heart.It opens into the right atrium between the opening of inferior vena cava, the fossa ovalis and the right.

The coronary circulation originating from a single coronary ostium is rare. All possible anatomical variations were the basis of a recent classification. This case report describes a previously unreported IID 1 pattern, comprising a solitary coronary ostium in the right coronary sinus with an anatomical course of the right coronary artery Discussion. In angiographic studies, the incidence of right coronary artery origin from the left aortic sinus is 0.17-0.38% [4,5].In some studies, this anomaly is considered as a variety of single coronary artery, even if both the coronary arteries originating from one orifice in the left sinus of Valsalva [].This anomaly was considered relatively benign in the absence of arteriosclerosis [] noun a short sinus receiving most of the veins of the heart; empties into the right atrium • Syn: ↑sinus coronarius • Hypernyms: ↑venous sinus, ↑sinus Coronary artery dilatation may be due to various aetiologies including congenital anomalies, atherosclerotic coronary disease, and Kawasakis disease. We describe a case characterised by apparent severe dilatation of the right coronary artery ostium in an asymptomatic male. Subsequent imaging and surgical intervention documented the presence of a sinus of Valsalva aneurysm extending into the.

There are no research studies that comprehensively analyze, with computed tomography, the coronary sinus (CS) ostium with respect to its importance for some electrophysiological procedures paying special attention to the Thebesian valve (ThebV). Our aim was to evaluate the characteristic features of the CS anatomy, which can be useful for electrophysiologists using multislice computed. Coronary sinus branch images closely resembled pathologic findings. Conclusion: Direct visualization of the coronary sinus ostium and branches is possible through infrared endoscopy. This technique likely will facilitate coronary sinus engagement and navigation for pacing lead and catheter placement
