However, PCI may be an acceptable alternative revascularization method to CABG when treating patients with less complex diseases (SYNTAX score <22), including left main." To put it another way, 75% of patients with left main or threevessel disease are still best treated with CABG, but for the remaining 25%, "PCI is an alternative to surgery, at least out to four years," Serruys commented.

19 Heart Team Approach to Revascularization Decisions I IIa IIb III A Heart Team approach to revascularization is recommended in patients with unprotected left main or complex CAD. I IIa IIb III Calculation of the STS and SYNTAX scores is reasonable in patients with unprotected left main and complex CAD.

20 Revascularization to Improve Survival: Left Main CAD Revascularization I IIa IIb III CABG to improve survival is recommended for patients with significant ( 50% diameter stenosis) left main coronary artery stenosis. I IIa IIb III PCI to improve survival is reasonable as an alternative to CABG in selected stable patients with significant ( 50% diameter stenosis) unprotected left main CAD with: 1) anatomic conditions associated with a low risk of PCI procedural complications and a high likelihood of a good long-term outcome (e.g., a low SYNTAX score [ 22], ostial or trunk left main CAD); and 2) clinical characteristics that predict a significantly increased risk of adverse surgical outcomes (e.g., STSpredicted risk of operative mortality 5%).

21 Revascularization to Improve Survival: Left Main CAD Revascularization (cont.) I IIa IIb III PCI to improve survival may be reasonable as an alternative to CABG in selected stable patients with significant ( 50% diameter stenosis) unprotected left main CAD with: 1) anatomic conditions associated with a low to intermediate risk of PCI procedural complications and an intermediate to high likelihood of good long-term outcome (e.g., low- intermediate SYNTAX score of <33, bifurcation left main CAD); and 2) clinical characteristics that predict an increased risk of adverse surgical outcomes (e.g., moderate-severe chronic obstructive pulmonary disease, disability from previous stroke, or previous cardiac surgery; STS-predicted risk of operative mortality >2%).

22 Revascularization to Improve Survival: Left Main CAD Revascularization (cont.) I IIa IIb III Harm PCI to improve survival should not be performed in stable patients with significant ( 50% diameter stenosis) unprotected left main CAD who have unfavorable anatomy for PCI and who are good candidates for CABG.

23 Revascularization to Improve Survival: Non- Left Main CAD Revascularization (cont.) I IIa IIb III I IIa IIb III CABG with a left internal mammary artery graft to improve survival is reasonable in patients with a significant ( 70% diameter) stenosis in the proximal LAD artery and evidence of extensive ischemia. It is reasonable to choose CABG over PCI to improve survival in patients with complex 3-vessel CAD (e.g., SYNTAX score >22) with or without involvement of the proximal LAD artery who are good candidates for CABG.

24 Revascularization to Improve Survival: Non- Left Main CAD Revascularization (cont.) I IIa IIb III CABG is probably recommended in preference to PCI to improve survival in patients with multivessel CAD and diabetes mellitus, particularly if a LIMA graft can be anastomosed to the LAD artery.

33 Unnecessary stenting case in Tennessee grabs government attention June 10, 2011 Reed Miller Jackson, TN - The US Department of Justice is looking into charges of fraudulent billing leveled by a Tennessee cardiologist against another cardiologist and two hospitals. Dr Wood Deming (Regional Cardiology Consultants, Jackson, TN) is accusing Dr Elie Hage Korban (Heart and Vascular Center of West Tennessee, Jackson) of "blatant overutilization of cardiac medical services, including, but not limited to, cardiac sonography, scintigraphic stress imaging, angiography, angioplasty, and stenting" in order to defraud government insurance programs, according to documents filed with the US District Court for Western Tennessee. Deming also alleges that the executives of Jackson-Madison County General Hospital and the Regional Hospital of Jackson and radiologist Dr Joel Perchik (Advanced Radiology, Jackson, TN) condoned or assisted in Korban's fraud in addition to engaging in a bilateral kickback and self-referral scheme [1].

38 Anesthetic Considerations I IIa IIb III Efforts are recommended to improve interdisciplinary communication and patient safety in the perioperative environment (e.g., formalized checklist-guided multidisciplinary communication). I IIa IIb III A fellowship-trained cardiac anesthesiologist (or experienced board-certified practitioner) credentialed in the use of perioperative TEE is recommended to provide or supervise anesthetic care of patients who are considered to be at high risk.

39 Intraoperative TEE I IIa IIb III Intraoperative TEE should be performed for evaluation of acute, persistent, and life-threatening hemodynamic disturbances that have not responded to treatment. I IIa IIb III I IIa IIb III Intraoperative TEE should be performed in patients undergoing concomitant valvular surgery. Intraoperative TEE is reasonable for monitoring of hemodynamic status, ventricular function, regional wall motion, and valvular function in patients undergoing CABG.

40 Bypass Graft Conduit I IIa IIb III When anatomically and clinically suitable, use of a second IMA to graft the left circumflex or right coronary artery (when critically stenosed and perfusing LV myocardium) is reasonable to improve the likelihood of survival and to decrease reintervention. I IIa IIb III Complete arterial revascularization may be reasonable in patients less than or equal to 60 years of age with few or no comorbidities.

41 Preoperative Antiplatelet Therapy I IIa IIb III In patients referred for elective CABG, clopidogrel and ticagrelor should be discontinued for at least 5 days before surgery and prasugrel for at least 7 days to limit blood transfusions. I IIa IIb III In patients referred for elective CABG, prasugrel should be discontinued for at least 7 days to limit blood transfusions.

42 Preoperative Antiplatelet Therapy (cont.) I IIa IIb III In patients referred for urgent CABG, clopidogrel and ticagrelor should be discontinued for at least 24 hours to reduce major bleeding complications. I IIa IIb III In patients referred for CABG, short-acting intravenous glycoprotein IIb/IIIa inhibitors (eptifibatide or tirofiban) should be discontinued for at least 2 to 4 hours before surgery and abciximab for at least 12 hours beforehand to limit blood loss and transfusions.

43 Preoperative Antiplatelet Therapy (cont.) I IIa IIb III In patients referred for urgent CABG, it may be reasonable to perform surgery less than 5 days after clopidogrel or ticagrelor has been discontinued and less than 7 days after prasugrel has been discontinued.
