MRI-related problems with metallic prosthetic grafts are the magnetic moment and the heating possibility.
New cardiac stents (produced in the last 5-8 years) are mostly out of non-magnetic material. 2-3 month after the stent implantation it is to expect that stents will be covered with tissue and a movement in the magnetic field is unusual. A small risk of heating caused by induction remains
(the risk depends on the field strength and the scanned region) - but the fast flowing blood is a good cooling system and reduces this risk in addition.
