Xray showed one of the wire of cardiac stent is ruptured. What are the complications? Is there anything that can be done?

Stent fracture. Stents are small tube-shaped devices implanted into blocked arteries to hold them open. Most are metal; recently other materials have been tested. Occasionally some of the metal struts fracture; this could not be seen on a plain Xray. "Rupture" means something different and is not likely to apply here. Most of the time stent fracture does not cause trouble. For personal advice consider a consult.
