The smallest cardiac veins (also known as the Thebesian veins (named for Adam Christian Thebesius) are small, valveless veins in the walls of all four heart chambers [1] that drain venous blood from the myocardium [2] directly into any of the heart chambers.

2023年11月3日 · The smallest cardiac veins, also known as the Thebesian veins, are small vessels of the heart that drain the inner surface of the myocardium. According to their location, the Thebesian veins are divided into four groups; Smallest right atrial veins; Smallest right ventricular veins; Smallest left atrial veins; Smallest left ventricular veins

2023年5月22日 · The Thebesian vessels or veins are embedded in the walls of the heart itself. They serve to drain the myocardium and are present in all four heart chambers. They are more abundant on the right side of the heart and, more specifically, …

2023年7月13日 · Otherwise known as Thebesian veins or small cardiac veins, these vessels range from 0.5 – 2 mm in diameter. Although they are difficult to map throughout the heart, they have been shown to drain directly into all cardiac chambers.

2023年6月20日 · The venae cordis minimae (singular: vena cordis minima), meaning "smallest cardiac veins", also known as Thebesian veins (variably capitalized in the literature) are a small group of valveless myocardial coronary veins within the walls of each of the four cardiac chambers that drain venous blood directly into each of the respective chambers.

A recent article 1 revisited the existence, nature, and imaging of so-called Thebesian veins, a phantomlike entity that has been mentioned in the medical literature since the early 1700s. In that article, Potu and colleagues 1 describe the incidental cannulation of a left ventricular (LV) Thebesian vein during LV angiography.

2023年7月24日 · The smaller cardiac venous system returns one-quarter of the deoxygenated blood from the inner layers of the myocardium to the cardiac chambers. This system is mainly composed of Thebesian veins draining deoxygenated blood from all sections of the myocardium chambers. Thebesian veins also drain the right side of the heart more than the left side.

The Thebesian veins are believed to have distinct functions. First, they provide a route of myocardial drainage driving carbon dioxide and other waste away from the tissue and back into the general circulation.

2023年5月22日 · The Thebesian vessels are unique to the cardiac circulation and help to drain the blood supply of the myocardium through a direct connection between the atrial and ventricular chamber lumina and the larger coronary vessels on the epicardial surface.

2 天之前 · There is an increased interest for the veins coursing in the left ventricular summit (LVS) area and could potentially provide a pathway to reach the LVS arrhythmogenic foci. ... (1708) as “thebesian veins” or “venae cordis minimae” [2, 4]. The coronary venous (CV) system plays a crucial physiological role in draining deoxygenated blood ...
