Coronary-artery stents and other endoluminal devices.

MORE than three years ago, a report was published in the Journal on the use of intravascular stents to prevent occlusion and re-Stenosis after transluminal angioplasty.1 Indications that the principal conclusion of the article was premature arose three months later, when diffuse narrowing was observed in some of the arteries with stents.2 This issue of the Journal contains a report by Serruys et al. on the results of follow-up angiography in 90 percent of the first 105 patients in whom coronary-artery stents were placed (mean follow-up time, 5.7±4.4 months).3 The authors are to be commended for reporting their follow-up results . . .
