Revascularization Versus Optimal Medical Therapy of Chronic Total Coronary Occlusions on Left Ventricular Ischemia Reduction — REVISE-CTO  

Chronic Total Occlusion of Coronary Artery Clinical Trial

Official title:
REvascularization Versus Optimal Medical Therapy on Left Ventricular ISchemia Reduction: Exploring the Associations Between Ischemia, Functional Outcome and Collaterals in the Treatment of Chronic Total Occlusion Patients

Clinical Trial Summary

Rationale: Randomized trials could not yet establish favourable outcomes of CTO PCI on hard endpoints such as ejection fraction or mortality, when compared to optimal medical therapy. However, patients after CTO PCI appeared to be more frequently free of angina complaints, but the aetiology behind this is not fully understood. The investigators hypothesize that PCI of the CTO in patients preselected with an ischemic threshold (>12.5%) on cardiac imaging leads to a reduction of the ischemic burden and therefore an increased benefit on functional outcomes. Objective: Primary objective is to determine whether PCI of the CTO will yield a higher reduction of ischemia assessed by exercise myocardial perfusion SPECT-CT from baseline to 6-month follow-up compared to a control group. Secondary objectives are 1) to evaluate the effect of PCI of the CTO on improvement in functional status, infarct size and left ventricular function from baseline to follow-up compared to the control group; 2) to study the association between ischemia reduction and functional outcome and left ventricular function; 3) to assess the influence of the collateral flow index on the ischemic burden (reduction), functional status, infarct size and left ventricular (contractile) function (hibernation). Study design: open multicentre randomized trial Study population: 82 patients eligible for CTO PCI Intervention: CTO PCI Primary endpoint: ischemic burden assessed with exercise myocardial perfusion SPECT-CT from baseline to 6 months follow-up.
