Interventional duct occlusion with the Rashkind PDA occluder has become a widespread alternative treatment to surgery. Whereas residual shunting is well-known, reopening of a completely occluded duct has been published in only 3 cases. We report another case of a young adult in whom ductal shunting reappeared after he had restarted physical exercise and sports activities soon after the occlusion procedure. Recanalization might have been due to changing of the device position without embolisation. A second Rashkind PDA occluder was successfully implanted 6 months after the first procedure with complete closure of the residual shunt.
