  Figure 1 Fluoro-angiographic procedural steps in latero-lateral projection. (A) Baseline aortic arch angiogram showing an elongated patent ductus (red asterisk) with marked narrowing towards the pulmonary artery side (type E, according to angiographic classification of Krichenko). (B) The 5-Fr delivery system passed retrogradely through the patent ductus arteriosus from the aorta and the 6-mm vascular plug system (Cera; Lifetech Scientific, Shenzhen, China) is being advanced inside it. (C) A selective angiogram through the 5-Fr delivery system confirming the position of the 6-mm vascular plug with a tiny residual shunt. (D) Final aortic arch angiogram showing abolition of the left-to-right shunt and the correct position of the occluding device.

  Figure 2 The vascular plug system (Cera; Lifetech Scientific, Shenzhen, China) is a self-expandable, cylindrical device coated with proprietary titanium nitride and available in various sizes range. Polytetrafluoroethylene membranes are dense and securely sewn into device to fill up the hole and block blood flow. In particular LT-PLUG-06 is 4-Fr compatible with an unconstrained plug length of 7 mm.
