Failure of the endocardial cushions to form will produce a classic congenital heart defect, an AV canal defect (also known as an endocardial cushion defect).
The ventricular septum is formed by contributions from the primitive ventricle and bulbus, the endocardial cushions, and the conal cushions (part of the tissue that develops into the pulmonary artery and aorta).
This indentation forms a crescent of tissue that folds in and actively grows downward toward the ventricles to meet the endocardial cushion tissue, which is simultaneously developing there.
