The formation of mixed blood in the atria is known as monoventricular. Monoventricular is a rare congenital heart disease, which is caused by the lack of development of both septum 1 and septum 2 of the atrial septum during embryonic development. Traces of the interatrial septum are also absent, and the interventricular septum is intact, so it is also called a two-chambered, three-chambered heart or a single-ventricle, three-chambered heart. A single atrium may exist alone, but it is often combined with a left superior vena cava and a right heart, a left heart or an abdominal visceral transposition malformation, and it is particularly common to have a cleft anterior mitral leaflet, or even the presence of an atrioventricular canal deformity. What are the dietary precautions for the formation of mixed blood in the atria?
