Abstract: The heart, fucntionally consists of four cavities; right atrium, right ventricle, left atrium and left ventricle. The blood vessels associated with the systemic and pulmonary circulation open into these heart cavities or take the blood out from the heart through these cavities. The oxygen-poor venous blood that comes to the lungs returns to the left atrium of the heart with four pulmonary veins which located two on the rightside and two on the leftside, after being oxygenated. During the routine dissection studies performed in the anatomy practice laboratory, it was observed that there were five pulmonary vein opening into the left atrium of the heart in the male cadaver. It was observed that two of these vessels opened to the left atrium from the right side and three of them opened to the left atrium from the left side. The course and localizations of other anatomical structures of the heart and anatomical structures adjacent to the heart were normal. In this rare case, the importance of the anatomy of the region in terms of clinical evaluations and surgical approaches was emphasized. As in our study, we believe that knowing such anatomical variations is important especially for interventional operations in the thorax region.Abstract: The heart, fucntionally consists of four cavities; right atrium, right ventricle, left atrium and left ventricle.
