There are three pericardial sinuses: superior, transverse and oblique. [1] The superior sinus is anterior to the ascending aorta and the pulmonary trunk. [1] It cannot be assessed in electrophysiology procedures. [1] The oblique sinus is an inverted J-shaped reflection of the venae cavae and pulmonary veins. [2]

Our study provides an anatomical classification of the pericardial sinuses. The individual variability of the sinuses’ morphology highlights the importance of understanding the clinical topography of the sinuses, particularly for minimally invasive thoracic ablation procedures.

2020年8月28日 · Formed as a result of the embryological folding of the heart tube, the transverse pericardial sinus is a passage through the pericardial cavity. It is located: Posterior to the ascending aorta and pulmonary trunk. Anterior to the superior vena cava. Superior to …

2023年7月24日 · As the serous pericardium reflects off various cardiac structures, it forms two sinuses: the transverse sinus and the oblique sinus. The oblique sinus is a cul-de-sac extending superiorly from the inferior vena cava between the two left pulmonary veins on one side and the two right pulmonary veins on the other.

2023年7月25日 · At their lines of reflection, the visceral and parietal pericardium layers create two sinuses. The transverse pericardial sinus, located posterior to the ascending aorta and anterior to the superior vena cava, is an important landmark to identify structures during CABG procedures.

2023年6月27日 · We analyzed 121 computer tomography scans (46.3% female, age of 66 ± 12 years) of the pericardial cavity. The oblique sinuses were classified into four types: 1 (shallow with narrow entrance), 2 (shallow with wide entrance), 3 (deep with narrow entrance), and 4 …

Pericardial sinuses are complex spaces within the pericardium that include the transverse sinus and cul-de-sacs, serving as important anatomical landmarks in the heart's surroundings.

2023年12月29日 · In this chapter, we have examined the genesis and anatomical details of the pericardial sinuses and recesses due to pericardial reflections around the great vessels, gross and ultrastructural features of fibrous and serous pericardium, applied anatomy, and physiology...

2023年6月27日 · The pericardial sinuses are an important anatomical feature of the pericardial cavity, however, their clinical anatomy has not been thoroughly studied. In this study, we aim to provide the first classification of the oblique and transverse sinuses.

Detailed drawings of four cross sections through the mediastinum which pass through the sinuses and recesses of the pericardial cavity, are presented. The drawings depict the location and extent of the pericardial sinuses, recesses, and their closely associated extrapericardial structures.
