Abstract:
A 7-month-old boy was admitted for the device closure of symptomatic patent ductus arteriosus (PDA) with moderate pulmonary hypertension. The PDA measured 4.2 mm with adequate ampulla. It was closed with an 8-6 mm Heart R device from pulmonary artery (PA) end. Post extubation, the device embolized to proximal descending thoracic aorta just distal to PDA ampulla. While attempting to snare from the venous side, the device self-repositioned to PDA. It was stable thereafter and patient was discharged after 2 days. We report a complication, which got self-corrected.
