For the interventionalist, proper sizing of coronary stents is critical. While imaging via angiography has been the standard for years, newer intravascular imaging technologies, such as IVUS and OCT, are becoming more widely used, as evidence accrues that these modalities make a difference in outcomes. For example, IVUS (Intravascular Ultrasound) not only allows the measurement of the exact open diameter of the vessel, as seen on angiography, but it shows the “invisible to angiography” layer of plaque. plaque that will be compressed, so that a more accurate post-PCI diameter can be determined. Under-expanded stents have been associated with increased stent thrombosis and restenosis. Continue reading

The stent was recommended by Bush’s doctors to open a blockage in one of his coronary arteries, found yesterday during what was described by Bush spokesman Freddy Ford as his annual physical exam at the Cooper Clinic in Dallas.

I started the wordplay about “Stent Wars” over a decade ago, a time when the competitive juices of the two device-makers, Boston Scientific and J&J/Cordis, were at an all time peak — each company was heavily marketing their first generation drug-eluting stent and every interventional cardiology meeting was saturated with “Cypher vs. Taxus” messaging.
