I had a massive MI/ Heart attack. I was stented @ widowmaker -6 months later after having bad chest pains for awhile- I had another heart cath. The stent had closed. The doctor did not do anything. I was scared that if it had closed & no blood was pumping thru it I wud die. I was told they couldn’t take it out. Then another heart cath. 2 months later the doctor said he put a larger stent over the closed stent. So one Dr did nothing and the next this. Can they really put a larger stent over it? I haven’t read anybody else having that done..Is this common or is it not usually done? Confused!!
