Transverse pericardial sinus
Sinus transversus pericardii
- Eponym: Thiele
Definition
The transverse pericardial sinus is open at both ends and formed by the reflection of visceral serosal pericardium from the posterior aspects of the aortic and pulmonary trunks over to the anterior aspect of the atrium. Thus, a finger in the transverse sinus will pass behind the aortic and pulmonary trunks, in front of the superior vena cava on the right, and the left atrial appendage on the left.
