Ten-year clinical and angiographic follow-up of coronary wallstent

Abstract

Although stents have been implanted in human coronary arteries since 1986, the long-term angiographic outcome of coronary stenting is unknown. We performed 10-year angiographic follow-up in 8 patients who had undergone stent implantation without acute complications or 6-months' restenosis. Analysis of the changes in minimal luminal diameter within the stent and the reference vessel diameter of the stented segment at 10 years do not suggest that atherosclerosis is accelerated or prolonged beyond 6 months within coronary stents.
