Thebesian veins as drainage to the ventricle: A case report

摘要

A 64-year old woman was referred to the division of cardiology due to recurrent angina pectoris (CCS III). The patient's symptoms and high cardiovascular risk profile were an indication for coronary angiography. Relevant coronary heart disease was hereby ruled out; however, angiography showed a direct drainage of coronary vessels into the chambers. These Thebesian veins are of venoluminal nature in most cases and have a clinical implication in selected cases only. The majority of the venous blood of the heart is returned by epicardial coronary veins and ultimately flows through the coronary sinus into the right atrium We report the case of a patient complaining of chest pain who underwent angiography due to suspected coronary artery disease. Angiography ultimately revealed an additional venous system, the casa cordis minimae.
