Pericardial sinus

From Wikipedia, the free encyclopedia

Space of the pericardium

Thepericardial sinuses are impressions in thepericardial sac formed between the points wheregreat vessels enter it.

Pericardial sinus
Posterior wall of the pericardial sac, showing the lines of reflection of the serouspericardium on thegreat vessels. (Transverse sinus labeled at center. Oblique sinus not labeled, but visible inferior to transverse sinus between the right and leftpulmonary veins)

Anatomical terminology [edit on Wikidata]

There are three pericardial sinuses: superior, transverse and oblique.^[1]

Thesuperiorsinus is anterior to theascending aorta and thepulmonary trunk.^[1] It cannot be assessed inelectrophysiology procedures.^[1]
Theoblique sinus is an invertedJ-shaped reflection of thevenae cavae andpulmonary veins.^[2] It lies behind theatria (particularly theleft atrium),^[1] and in between left and right pulmonary veins.
Thetransverse sinus is the tunnel-shaped passage posterior to theaorta andpulmonary trunk, and anterior to thesuperior vena cava.^[1]^[2] This sinus is clinically important because passing one end of clamp through the sinus, and the other end anterior to the aorta/pulmonary trunk will allow complete blockage of blood output. This is performed during someheart surgeries.^{[citation needed]}

Duringpericardial effusion,fluid may build up in the pericardial sinuses.^[3] This may be diagnosed withtransoesophageal echocardiography.^[3]
