● below – by the right atrium and its auricula dextra.
On the left the entrance in sinus transversus is limited:
● in front and from above – by truncus pulmonalis and
auricula sinistra;
● behind – by fold of the left vena cava (Marshall vestigial
fold) which goes from a. pulmonalis sinistra to v. pulmonalis
superior;
● below – by auricula sinistra.
Thus, the sinus transversus pericardii is located behind the
ascending part of aorta and truncus pulmonalis. If to put the
finger in sinus transversus pericardii one can bypass and press
the ascending part of aorta and truncus pulmonalis. This
technique is used in heart surgery and surgery of large blood
vessels.
Oblique pericardial sinus, Haller (sinus obliquus pericardii)
is located behind the heart. We can see it if to move the apex
of the heart up and right. Sinus obliquus pericardii can be the
place of liquid and blood accumulation, and as a rule is
drained during the surgery.
The sinus obliquus pericardii is limited:
● in front – by dorsal surface of atrium sinistra;
● behind – by dorsal wall of pericardium between the
pulmonary vein entrances;
● on the right side and below – by v. cava inferior;
● on the left and from above – by left pulmonary veins.
The general source of blood supply of pericardium is
a. pericardiacophrenica, the branch of internal thoracic artery.
Apart from it a. thoracica interna, rr. pericardiaci from thoracic part
of aorta, branches from thymic artery, and branches from
intercostal, esophageal, bronchial and mediastinal arteries take
