14 Multivessel CAD: What do the Guidelines Recommend?

15 ACC/AHA Guidelines for Chronic Stable Angina 2002 Class I (PCI) Percutaneous coronary intervention for patients with two- or three-vessel disease with significant proximal LAD CAD, who have anatomy suitable for catheter based therapy and normal LV function and who do not have treated diabetes. (Level of Evidence: B) Percutaneous coronary intervention or CABG for patients with one- or two-vessel CAD without significant proximal LAD CAD but with a large area of viable myocardium and high-risk criteria on noninvasive testing. (Level of Evidence: B) In patients with prior PCI, CABG or PCI for recurrent stenosis associated with a large area of viable myocardium or high-risk criteria on noninvasive testing (Level of Evidence: C) Percutaneous coronary intervention or CABG for patients who have not been successfully treated by medical therapy (see text) and can undergo revascularization with acceptable risk. (Evidence: B)

16 ACC AHA SCAI Guidelines for Chronic Stable Angina 2002 Class IIa Repeat CABG for patients with multiple saphenous vein graft stenoses, especially when there is significant stenosis of a graft supplying the LAD. It may be appropriate to use PCI for focal saphenous vein graft lesions or multiple stenoses in poor candidates for reoperative surgery. (Level of Evidence: C) Use of PCI or CABG for patients with one- or two-vessel CAD without significant proximal LAD disease but with a moderate area of viable myocardium and demonstrable ischemia on noninvasive testing. (Level of Evidence: B) Use of PCI or CABG for patients with one-vessel disease with significant proximal LAD disease. (Level of Evidence: B)

17 ACC AHA SCAI Guidelines for Chronic Stable Angina 2002 Class IIb Compared with CABG, PCI for patients with two- or three-vessel disease with significant proximal LAD CAD, who have anatomy suitable for catheter-based therapy, and who have treated diabetes or abnormal LV function. (Level of Evidence: B) PCI for patients with one- or two-vessel CAD without significant proximal LAD CAD who have survived sudden cardiac death or sustained ventricular tachycardia. (Level of Evidence: C)

18 ACC AHA SCAI Guidelines for Chronic Stable Angina 2002 Class III Use of PCI or CABG for patients with one- or two vessel CAD without significant proximal LAD CAD, who have mild symptoms that are unlikely due to myocardial ischemia, or who have not received an adequate trial of medical therapy and a. have only a small area of viable myocardium or b. have no demonstrable ischemia on noninvasive testing. (Level of Evidence: C) Use of PCI or CABG for patients with borderline coronary stenoses (50% to 60% diameter in locations other than the left main coronary artery) and no demonstrable ischemia on noninvasive testing. (Level of Evidence: C) Use of PCI or CABG for patients with insignificant coronary stenosis (less than 50% diameter). (Level of Evidence: C)

25 Extent of Revascularization?

26 ARTS: Completeness of Revascularization Complete Revascularization in 84.1% of Surgery Patients Complete Revascularization in 70.5% Of PCI patients. (p<0.001). One year Event Free Survival in PCI: 69.4 vs. 76.6% in favor of greater revascularization. (p<0.05). Need for subsequent revascularization 10.0% vs. 2.0%. (p<0.05). Surgery with incomplete revascularization showed no significant difference. Mortality was not effected in either group.

52 Multivessel PCI PCI remains limited by complex anatomic and Patient subsets. Risk Assessment is critical to picking the optimal patients for MV PCI. Vascular Risk Management is an integral component of patient outcome. CABG remains an important treatment modality, particularly for high risk patients or patients requiring adjunctive procedures. Better technology offers promise for increasing opportunities for PCI.
