Atrioventricular canal malformation

Atrioventricular tube malformation, also known as endocardial pad defect and atrioventricular septal defect, is a cardiac malformation caused by the incomplete development or pause of the central endocardial pad during embryonic development. The lesions include the abnormalities of upper atrial ventricular valve, lower atrial ventricular septal defect and atrioventricular valve, forming a composite malformation from simple primary foramen atrial septal defect to huge ventricular septal defect and severe abnormalities of mitral and tricuspid valves at the same time. Atrioventricular canal defects are rare in clinic. The incidence rate of male and female is basically the same. Because of severe heart malformations, severe heart failure and pulmonary hypertension often occur in infants.
