General Conversation
Atrioventricular septal defect (ASVD) is a basic term for a group of rare heart flaws that are present at birth (hereditary). Babies with ASVDs have actually improperly created atrial and ventricular septa and adjoining shutoffs.

The typical heart has four chambers. The two top chambers, called atria, are divided from each other by a coarse partition called the atrial septum. Both lower chambers, known as ventricles, are separated from each various other by the ventricular septum. Shutoffs (e.g., mitral and also tricuspid) connect the room (left and right) to their particular ventricles. The shutoffs enable blood to be pumped via the chambers. Blood takes a trip from the right ventricle through the pulmonary artery to the lungs where it gets oxygen. The blood returns to the heart with lung capillaries and also enters the left ventricle. The left ventricle sends the currently oxygen-filled blood into the main artery of the physical body (aorta). The aorta sends the blood throughout the body.

The parts of the heart described above are formed from an embryonic structure called the endocardial cushions. In people with ASVD there is some mix of malformation of these components of the heart. They might consist of an opening in the atrial septum, a hole in the ventricular septum, and/or abnormalities of the mitral as well as triscupid valves. ASVD might be identified as one of 3 types: an incomplete (or partial) ASVD (atrial septal flaw primum); a transitional type (atrial septal problem as well as little ventricular septal flaw); or a more extreme or full form (huge atrial and ventricular problems).

The symptoms of ASVD differ considerably and also rely on the severity of the malformations (e.g., shutoff leak in between ventricles and also ventricular size). About half the cases of ASVD happen in youngsters with Down syndrome.
