Design of pmVSD and mVSD on a heart model with PDA. a The outlines of the VSDs were drawn on the surface of both sides of the ventricle septum and connected by a tubular surface. The resulting cone-shaped object was subtracted from the original model via Boolean operations. b Flap-shaped windows (marked by arrows) were included to enable examination of the interior of the model once 3D printed in flexible material
