Patient's question:
Since birth, it has been found that there is a congenital heart disease. Now she is 3 years old.Doctor's answer:
Endocardial cushion defect is also known as atrioventricular septal defect or atrioventricular canal defect, which is a developmental disorder caused by the failure of endocardial cushion fusion during the embryonic period in the inflow tract of the ventricle. Patients with small shunts may have no symptoms, while those with complete endocardial cushion defect typically exhibit typical congestive heart failure symptoms in the early postnatal period.
