Atrioventricular canal defect results from an abnormal or inadequate fusion of the superior and inferior endocardial cushions. Both the complete and partial types of the defect are associated with the ostium primum defect in the lowermost portion of the atrial septum, left ventricular outflow narrowing and the atrioventricular valve abnormalities. The clinical diagnosis of partial atrioventricular canal defect can be confirmed by cardiac ultrasound. The aim of this paper is to preset an educational ultrasound image of partial atrioventricular canal defect.
