While the disappearing drug-eluting stent seems to have faded from view for the time being, several manufacturers have invested in fabrication of drug-eluting stents with polymers that absorb once the drug of elution has done its work. A new study indicates that patients who have already had a myocardial infarction fare better on stents made with these biodegradable polymers, an outcome that may soon push second-generation DES devices into med-tech history.
The controversy over paclitaxel (PCT)-associated mortality in devices for the peripheral arteries is far from over, but another medical journal article has punched a hole in the credibility of the paclitaxel theory with the conclusion that the evidence is unequivocal and may be unpersuasive to physicians.
The recent controversy over the use of paclitaxel in the peripheral vasculature has clouded the larger debate over whether bypass is superior to endovascular therapies for the lower limbs. However, a new study suggests that nitinol stents provide a feasible alternative to bypass even for lesions of the femoropopliteal artery that are 30 cm in length.
