Evidence based myocardial revascularization
CABG is clearly superior to Medical Management
SYNTAX trial shows superior survival with CABG over first-generation, paclitaxel-eluting stents for 3VD
Guidelines favours CABG for complex MV disease
Differences between PCI and CABG appear particularly with higher degree of incomplete revascularization
![Page 33: Cabg is superior to pci in heart failure patients with multivessel disease pro](https://reader031.fdocuments.net/reader031/viewer/2022021506/5877bba11a28ab2c668b6bc3/html5/thumbnails/33.jpg)
Evidence based myocardial revascularization
Surgery, since the beggining showed better results when patients had an LV dysfunction
PCI is an alternative to CABG for low SYNTAX score, but still more repeat revascularizations are required
CABG is economically attractive
![Page 34: Cabg is superior to pci in heart failure patients with multivessel disease pro](https://reader031.fdocuments.net/reader031/viewer/2022021506/5877bba11a28ab2c668b6bc3/html5/thumbnails/34.jpg)
Conclusions to take home
1• In 2015, CABG turned 50 years old…Many, many patients benefited.
2• SYNTAX trial and others show superior survival with CABG over first-
generation stents for 3VD
3• Differences between PCI and CABG appear particularly with higher
degree of incomplete revascularization
6• CAD patients with poor LV function or HF are better treated by
surgery, but Heart Team assessment is, in 2015, mandatory
4• CABG is superior to PCI in diabetic patients, irrespective of insulin
dependence
5• PCI provides similar outcomes as CABG 3VD patients with low or
intermediate SYNTAX scores
