Is it contraindicated to get more than one stent during a cardiac catheterization procedure?

No. No, we do it all the time. Although it is unusual, I have put in as many as 7 stents at one time. The average number of stents per patient is 1 .5.
No. Often, more than 1 stent is required if narrowing of the coronary arteries is discovered and in need of treatment.
