Feasibility and Effectiveness of a Real-time Heart Team Approach in Complex CAD

Inclusion Criteria: 1. Significant stenosis in the left main or left main equivalent with or without stenosis in one of the other vessels\[Significant stenosis is defined as: 1) a diameter stenosis of at least 50% reduction in luminal diameter by visual assessment or 2) any total occlusion (no age limitation and no exclusion of unfavorable anatomic features); Left main equivalent disease is defined as significant stenosis of the ostium of the left anterior descending and the ostium of the left circumflex.\] 2. At least 1 significant stenosis (≥ 70% obstruction) in all 3 major epicardial territories supplying viable myocardium; 3. Other conditions that the interventional cardiologist considers necessary to discuss with cardiac surgeons due to technical and risk considerations. Exclusion Criteria: 1. Less than 18 years of age; 2. Previous history of PCI or CABG; 3. Admitted for AMI, ECG and biomarker detection indicated acute stage; 4. Patients with severe heart valvular disease, major vascular disease, and giant ventricular aneurysm require surgical treatment; 5. Combined with AF or severe arrhythmia; 6. Other patients admitted to hospital due to emergency circumstances who are not suitable to wait for elective revascularization; 7. Rejection or exclusion of a revascularization mode (PCI or CABG); 8. Refuse to participate in the study.
