Figure 4. Angiographic (A) and echocardiographic (B) correlation showing the measurements of the ductus arteriosus, being * pulmonary ampulla, ** aortic ampulla, and *** length of the ductus arteriosus, fundamental for choosing the device. C) Piccolo© device. D and E) Device released showing good final positioning, without residual shunt.
