Washington, DCA newer class of heart stents are under investigation by the FDA. According to US health regulators, these tiny tubular devices made of wire mesh may shrink or lengthen after implantation, which can potentially cause a serious problem.
As reported by the agency, drug-eluting stents that are causing the most frequent problems are those in the Promus Element (not sold in the US) and Ion devices made by Boston Scientific Corp.
Drug-eluting stents are designed to prop open damaged arteries and deliver medicine to keep them from clogging again. But if the stent becomes deformed inside the vessel, the device could create a clotting risk that could lead to a heart attack.
According to publications in the Journal of Interventional Cardiology there have been concerns that some stents are poorly designed to resist shortenting. The Journal reported one case where a patient’s artery shortened and accordioned after Boston Scientific’s Ion stent was implanted. He then suffered a heart attack.
Boston Scientific, the biggest manufacturer of stents, has more than a third of the $4 billion global market. The company has recalled a number of stents that date back to 2004.

I had 2 stents (Synergy) in sept. 2016. I had heart attack in January 2017. 4 stents were placed in February 2017. I read the cath report describes one stent as hanging out. This a concern but is not reported I understand the synergy stent has been replaced. Is this true or is my heart failing?

I have 8 stents Boston Scientific, Promus. I was wondering I have received all of them from 2009 and currently. I am currently going to the hospital for what seems like by weekly and or monthly with constant complications. Some they replace others they just keep me there until chest pains go away. I don't know what to do. I'm a 45 year old female.

I had a Talus stent put in 2004 and had a stent thrombosis 9 months after I went off of plavix. I then stayed on plavix for ten years. In March of this year in anticipation of hand surgery I went off of plavix again. I had another stent thrombosis five days later.
Any thing you can do?

I had three stents in Aug. 09 implanted . One was used inside of an endeavor stent because they said is was closing only three months after it was put in. They cleaned it out and put the promus inside of that one. Now what am I looking at in the way of more problems?

I had a Promus stent implanted 6-11-2010. During rehab I had a setback during the month of October 2010 where my stamina was reduced by about 90 percent. No pain. I had a chemical stress test recently which showed a 66 percent expulsion which was the same as April 2010. I am 75 and a controlled diabetic. Any suggestions?

PROMUS is still being marketed in U.S. My husband had FIVE stents inserted in Sept. 2011 - all 5 are the PROMUS drug-eluting stents from BOSTON Scientific. We were given the STENT identification cards by the cardiologist who performed the surgery at time of surgery. WHEN WERE THE PROMUS STENTS recalled?
