There are two Pericardial sinuses: transverse and oblique.

• The cul-de-sac enclosed between the limbs of the inverted U of the venous mesocardium lies behind the left atrium and is known as the oblique sinus.^[1]

• The passage between the venous and arterial mesocardia—i.e., between the aorta and pulmonary artery in front and the atria behind—is termed the transverse sinus.^[2]
