That would be variant upon what kind of stent was placed in his heart. However, the good news is most stents last forever because they are made of a special metal material. But there are some stents on the market that dissovle after being in the artery after 3 years. If sounds like his may be permanent, but they best way to find out is to talk to the cardiologist to find out which he has and how often it needs to be repalced. Hope this helps!

To open an artery near the heart
Heart stents, made of a small mesh tube are used to prevent heart attacks by keeping coronary arteries open. They are often inserted following non-invasive procedures such as angioplasty, which also works to keep blood flowing through arteries. Stents are inserted via a balloon catheter, which guides the stent into place in the narrowed artery. The balloon is deflated and the stent then expands to hold open the artery. Heart tissue heals around the stent over a period of several weeks. Stents sometimes contain medicine to lessen the possibility of reblockage due to plaque.
a Stent is a short narrow metal or plastic tube often in the form of a mesh that is inserted into the lumen of an artery especially to keep a previously blocked passageway open, my mother in law had one of these put into her legs to keep the blood flowing to her heart....
