We describe two cases of spontaneous embolisation and successful retrieval of ceramic-coated patent arterial duct devices. In both, the device embolised to the descending aorta in the absence of pulmonary hypertension and despite optimum placement. We have discussed possible mechanisms for embolisation in these patients and suggested alternative methods for device retrieval. Based on this limited experience, we conclude that for tubular ducts, ceramic-coated devices should be oversized to form a tighter waist or alternate devices may be considered.
