Abstract:
Stent embolization is a complication that usually requires surgical extraction. We report a case where the covered stent used in MELODY valve trans-catheter pulmonary valve placement embolized to the right ventricle after being fully dilated on a 24-m-diameter balloon. After several unsuccessful attempts trying to capture it back or push it forward to the intended landing zone, we succeeded in deploying another stent straddling the embolized stent to anchor both of them in the main pulmonary artery. Two months later, we performed the valve implantation supported by both pre-stents.
