Pronunciation: [pˌɛɹɪkˈɑːdɪəl vˈe͡ɪn] (IPA) 
The pericardial vein is a critical component of the heart's circulatory system. It is responsible for carrying blood from the pericardium, the sac surrounding the heart, to the azygos and superior vena cava veins, which then transport it to the right atrium of the heart. Although the pericardial vein is the most commonly used term, it is also known by other synonyms. These include the sinuatrial vein, ascending venous branch, and the sinus venosus. Healthcare professionals often use these interchangeable terms to refer to this vital blood vessel during heart operations, imaging scans, and other medical procedures.
