A Multicentre, Pilot Study to Evaluate the Safety and the Feasibility of Planning and Execution of Surgical Revascularization in Patients With Complex Coronary Artery Disease, Based Solely on MSCT Imaging Utilizing GE Healthcare Revolution CT and HeartFlow FFRCT.

Inclusion criteria

• ✓. Patient referred to CABG treatment (as assessed by 'conventional Heart Team');
• ✓. Patients with at least 1 stenosis (visually determined de novo lesions with ≥50% DS) in all 3 major epicardial territories (LAD and/or side branch, CX and/or side branch, RCA and/or side branch) supplying viable myocardium with or without left main involvement;
• ✓. Patients with hypoplastic right coronary artery (RCA) with absence of descending posterior and presence of a lesion in the LAD and circumflex (CX)territories may be included in the trial as a 3vessel disease equivalent. Ostial LAD plus ostial left circumflex artery (LCX) may be included in the trial as a Left Main equivalent
• ✓. Distal vessel size should be at least 1.5 mm in diameter as visually assessed in diagnostic angiogram;
• ✓. Patient with silent ischemia, chronic stable angina or stabilized acute coronary syndromes with normalized (stable or decreasing) cardiac biomarker values Note: For patients showing elevated Troponin (cTn) (e.g. non-STEMI patients) at baseline (within 24h pre-CABG) an additional blood sample must be collected prior to the CABG procedure to confirm that: • hs-cTn or Troponin I or T levels are stable, i.e. the value should be within 20% range of the value found in the first sample at baseline, or have dropped • CK-MB and CK levels are within normal range If hs-cTn or Troponin I or T levels are stable or have dropped, or the Creatine kinase-MB (CK-MB) and Creatine kinase (CK) levels are within normal ranges, and the ECG is normal, the patient may be included in the study.
