Study Design: Allocation: Non-Randomized
Intervention Model: Single Group Assignment
Masking: Open Label
Primary Purpose: Treatment

Primary Outcome Measures:
  • angiographic in-lesion late loss [ Time Frame: 6 months post-procedure ]

Secondary Outcome Measures:
  • in-stent mean percent diameter stenosis (%DS) [ Time Frame: 6-months post-procedure ]
  • i-stent late loss (LL) [ Time Frame: 6 months post-procedure ]
  • in-lesion binary restenosis [ Time Frame: 6-months post-procedure ]
  • Target Vessel Revascularization (TVR) [ Time Frame: 9-months post-procedure ]
  • Target Vessel Failure (TVF) defined as any revascularization of the index vessel or myocardial infarction or death that cannot be clearly attributed to a vessel other than the index vessel [ Time Frame: 9 months post-procedure ]
  • Composite of Major Adverse Cardiac Events (MACE) defined as death, myocardial infarction (Q wave and non-Q wave), emergent bypass surgery, or repeat target lesion revascularization in-hospital [ Time Frame: 1, 6, 9 months and, 2 and 3 years post-procedure ]
  • occurrence of bleeding [ Time Frame: 1, 6, 9 months and, 2 and 3 years post-procedure ]

Arms Assigned Interventions
Cypher™ sirolimus-eluting stent
Device: drug-eluting stent
Other Name: Cypher™ sirolimus-eluting stent

Detailed Description:
This is a multicenter (11 sites), non-randomized study. Patients who meet the eligibility criteria will be treated with the Cypher™ sirolimus-eluting stent. All patients will have a repeat angiography at six months post-procedure and will be additionally followed clinically at 1, 6 and 9 months and up to 3 years. The results of this study will be compared with the outcome of the GAMMA I / II as the historical control.

Ages Eligible for Study:   18 Years and older   (Adult, Senior)
Sexes Eligible for Study:   All
Accepts Healthy Volunteers:   No

Inclusion Criteria:

  1. The patient has an in-stent restenosis of ≥ 60% and < 100% (by QCA online of the MLD compared to the distal reference diameter) in a native coronary artery.
  2. The study target lesion can not be located in a vessel containing another lesion requiring treatment. Lesions located in other vessels may be treated with percutaneous revascularization at the time of the procedure, BUT they must be successfully treated prior to the treatment of the study target lesion.

Exclusion Criteria:

  1. Unprotected left main coronary disease with ≥ 50% stenosis;
  2. Patient previously treated with brachytherapy in any coronary vessel.
  3. Target lesion involves bifurcation including a side branch >2.5mm in diameter.
  4. The patient sustained a recent (<72 hours) myocardial infarction defined as a serum CK 2x the upper limit of normal and elevated MB or abnormal lab values.
