The pericardial sinuses are impressions in the pericardial sac formed between the points where great vessels enter it.
Pericardial sinus
Posterior wall of the pericardial sac, showing the lines of reflection of the serous pericardium on the great vessels. (Transverse sinus labeled at center. Oblique sinus not labeled, but visible inferior to transverse sinus between the right and left pulmonary veins)
The pericardialsinuses are impressions in the pericardial sac formed between the points where great vessels enter it. There are three pericardial sinuses:...
