Overview
Based on the anatomical features and their impact on physiology, endocardial cushion defect may be classified into complete, partial, intermediate, transitional, and intermediate forms.
Classification
Based on the anatomical features and their impact on physiology, endocardial cushion defect may be classified into complete, partial, intermediate, transitional, and intermediate forms.[1]
