Hi, My husband just had a stent placed inside of a stent that had already been placed inside of a stent. It seems that he needs a couple every two to three years. He now has a total of 8. He is 63 years old and has a history of 2 MI's at 38 and 40 years old, and pacemaker/defibrillator at 60. What can be expected both in terms of prognosis and side effects from a triple layered stent.
