Coronary Veins Comprehensive CTAnatomic Classification and Review of Variants and Clinical

A prominent crista terminalis is a well-defined fibromuscular ridge formed by the junction of the sinus venosus and primitive right atrium (RA) extending along the posterolateral aspect of the right atrial wall, which is a normal anatomic variant and recognized by echocardiography occasionally [ 1, 2 ].

Embryology cardiovascular system (heart development)

The sinus venarum (also known as the sinus of the vena cava, or sinus venarum cavarum [1]) is the portion of the right atrium in the adult human heart [2] where the inner surface [3] of the right atrium is smooth, [2] [3] whereas the rest of the inner surface is rough [3] (trabeculated [2]) due to the presence of pectinate muscles. [4]

Sinus Venarum Cavarum

The anastomosis of the cranial vena cava and the common hepatic vein formed the sinus venarum cavarum (Fig. 8b). On the other hand, the large azygos vein opened into a distended coronary venous sinus (Fig. 8b). The position and morphological findings of the lungs were normal (Fig. 9).

Anatomy of the heart Osmosis

Bilateral nerve branches originating from the stellate and thoracic sympathetic ganglia until T5 or T6 joined to form the plexuses in the sinus venarum cavarum of the right atrium (RA), from which the branches descending along the middle cardiac vein (MCV) extended (arrowhead) and approached to the crux (sinoatrial node) of the heart (broken line).

Right atrium anatomy, right atrium function & valves

In mammals, the sinus venosus exists distinctly only in the embryonic heart where it is found between the two venae cavae; in the adult, the sinus venosus becomes incorporated into the wall of the right atrium to form a smooth part called the sinus venarum which is separated from the rest of the atrium by a ridge called the crista terminalis.

Gross anatomy The right atrium receives deoxygenated blood from the superior vena cava (SVC), the inferior vena cava (IVC), the coronary sinus (covered by the Thebesian valve), and the Thebesian veins. It is grossly the shape of an irregular ellipsoid, with the exception of the right atrial appendage (auricle), which arises anteriorly.

Sinus venarum (sinus venarum cavarum) Is a posteriorly situated, smooth-walled area that is separated from the more muscular atrium proper by the crista terminalis. Develops from the embryonic sinus venosus and receives the SVC, IVC, coronary sinus, andanterior cardiac veins.
