Atrium Single

Single atrium

In the Medical Encyclopedia you can read the following definition of this concept: “The atria normally in humans and vertebrates consist of two cavities: the right and the left. In humans, the left heart consists of four chambers: two atria - the upper (right) and lower (left), connected by the atrioventricular foramen, and two ventricles, right and left, connected by the preventricular-ventricular fissure. Accordingly, the human right is the atrium located frontally on the right.

What determines the maturation of this anomaly? This disease is observed in newborns, usually girls, but it also affects adult men. The reason is impaired venous outflow of blood on the pulmonary branches of the pulmonary circulation. As a result of hypovolemia of the vascular system of the anterior mediastinum, the division of the cardiac atrium is disrupted. But should this mean that surgery for such a disease is one hundred percent indicated? Yes, the doctor decides surgical tactics individually for each patient. Often congenital heart defects lead to the atrium alone, leading to dysfunction of the valve apparatus.
