AngiographiC Evaluation of the Everolimus-Eluting Stent in Chronic Total Occlusions - the ACE-CTO Study (ACE-CTO)

Chronically total occlusions (CTO) are difficult to treat and have high risk for restenosis. Although everolimus-eluting stents (EES) [(Xience, Abbott Vascular) or Promus (Boston Scientific)] are very promising for the treatment of CTOs due to their low late loss and excellent deliverability, there are currently no published data on EES implantation in CTOs.

The specific aim of this proposal is to examine the 8-month incidence of binary angiographic in-stent restenosis (defined as a stenosis of > 50% of the minimum lumen diameter of the target stent) after implantation of the EES in CTO.

It is the investigators hypothesis that EES-treated CTO lesions will have ≤ 20% 8-month in-stent binary angiographic restenosis rate.

  2. Recent positive pregnancy test, breast-feeding, or possibility of a future pregnancy
  3. Coexisting conditions that limit life expectancy to less than 12 months
  4. Patients who have a creatinine above 2.5 mg/dL (unless they require hemodialysis, in which case they are eligible to participate)
  5. History of an allergic reaction or significant sensitivity to everolimus
