Triatrial Heart, also known as Cor Triatum, is a rare birth defect in the heart. The human heart typically has four chambers, two ventricles and two atria. The two atria are ordinarily isolated from each other by a space called the atrial septum and the two ventricles by the ventricle septum. In cor triatriatum there is a little additional chamber over the left chamber (cor triatriatum sinistrum) or right chamber (cor triatriatum dextrum).
This additional atrial chamber can cause slow blood flow from the lungs to the heart and, after some time, prompts congestive heart failure and heart obstruction.
In kids, cor triatriatum might be related to major inborn heart issues. In grown-ups, it is usually an isolated finding. Treatment relies on the symptoms and may include medical and surgical methods.
