NCT06908499

Brief Summary

The goal of this clinical trial is to compare long term efficacy of drug-eluting stent implantation compare to optimal medical treatment in patient with chronic total occlusion in a very long-term follow-up (minimum 10 years) period.

Study Population

Patients with chronic total occlusion who were enrolled in the original DECISION-CTO trial (NCT01078051)

You may qualify if:

  • Clinical 1) Patients with angina or silent ischemia and documented ischemia 2) Patients who are eligible for intracoronary stenting 3) Age \>18 years
  • Angiographic 1) De novo lesion Chronic Total Occlusion (CTO) 2) Reference vessel size ≥ 2.5 mm by visual estimation 3) At least one CTO lesions located in proximal or mid epicardial coronary artery.
  • (If the patient has two CTO lesions, one CTO lesion should be located in proximal or mid epicardial coronary artery)
  • CTO definition: TIMI (Thrombolysis in Myocardial Infarction) flow 0 or 1 with estimated duration over 3 months
  • The duration of the occlusion was determined by the interval from the last episode of acute coronary syndrome, or
  • In patients without a history of acute coronary syndrome, from the first episode of effort angina consistent with the location of the occlusion
  • Angiographically defined total occlusion over 3 months
  • If no definite symptom with total occlusion, two experienced operators decide CTO in consideration of angiographical morphology (degree of calcification, bridging collaterals, non-tapered stump, angiographic filling from collaterals)

You may not qualify if:

  • History of bleeding diathesis or coagulopathy
  • Pregnant state
  • Three vessel CTOs
  • Known hypersensitivity or contra-indication to contrast agent and heparin
  • ST-elevation acute myocardial infarction requiring primary stenting
  • Culprit total occlusion presented with acute coronary syndrome suggesting acute or recent occlusion
  • Characteristics of lesion 1) Left main disease 2) In-stent restenosis 3) Graft vessels 4) Distal epicardial coronary artery CTO lesions 5) Two vessel proximal segment CTOs
  • Hematological disease (Neutropenia \<3000/mm3, Thrombocytopenia \<100,000/mm3)
  • Hepatic dysfunction, liver enzyme (ALT and AST) elevation ≥ 3 times normal
  • Renal dysfunction, creatinine ≥ 2.0mg/dL
  • Contraindication to aspirin, clopidogrel or other commercial antiplatelet agent
  • Left ventricular ejection fraction \<30%
  • Patients who are actively participating in another drug or device investigational study, which have not completed the primary endpoint follow-up period.
  • Non-cardiac co-morbid conditions are present with limited life expectancy or that may result in protocol non-compliance (per site investigator's medical judgment).
