Endocardial cushion defect

Atrioventricular (AV) canal defect; Atrioventricular septal defect; AVSD; Common AV orifice; Ostium primum atrial septal defects; Congenital heart defect - ECD; Birth defect - ECD; Cyanotic disease - ECD

Endocardial cushion defect (ECD) is an abnormal heart condition. The walls separating all 4 chambers of the heart are poorly formed or absent. Also, the valves separating the upper and lower chambers of the heart have defects during formation. ECD is a congenital heart disease, which means it is present from birth.

Ventricular septal defect

Ventricular septal defect is a congenital defect of the heart, that occurs as an abnormal opening in the wall that separates the right and left ventricles. Ventricular septal defect may also be associated with other heart defects. Many small defects will close on their own. For those defects that do not spontaneously close, the outcome is good with surgical repair.

Atrial septal defect

An atrial septal defect is a congenital heart defect where the wall between the right and left atria does not close properly, leaving a hole between the two atria.

Atrioventricular canal (endocardial cushion defect)

Endocardial cushion defect is an abnormal heart condition which occurs during the development of the baby. In this condition there is no separation between the chambers of the heart. Without the separation, oxygen-rich and oxygen-poor blood mix causing the heart to work harder. Endocardial cushion defect is strongly associated with several genetic abnormalities.
