Pericardial reflection around the venous aspect of the heart

The authors have studied the pericardial recesses of the venous aspect of the heart. They report 107 anatomical dissections on fresh cadavers with the cardiac cavities artificially filled. Variations in the number of the pulmonary vv., in their diameters and their pericardial segments are reported. The characteristics of the oblique sinus, of the postcaval and pulmonary recesses are also reported. These variations define five types of pericardial morphology. A classification is proposed. These results differ from those in the literature, possibly because the pericardial reflection is delineated in diastolic filling of the cavities. These morphometric data are useful in anatomic instruction, imaging of the mediastinum, and the surgery of malignant tumors and pulmonary transplantation.
