It was reported that the procedure was to treat a moderately tortuous, non-calcified patent ductus arteriosus (pda) that was 30% stenosed for a pediatric patient.A 9.0 x 19mm omnilink elite was advanced to the target lesion.However, the stent shifted proximally from the balloon while attempting to cross in the pulmonary artery.The device was simply withdrawn as a single unit along with the sheath.The procedure was then completed because the site had no additional 9.0 x 19mm omnilink elite in their inventory.There was no clinically significant delay in the procedure and no adverse patient effects.No additional information was provided.
