PRACTICAL CONCLUSIONS MVD with high SYNTAX Score CABG should be considered as first choice paricularly when :considered as first choice paricularly when :
Patients who need - as ITT - > 4-5 stentsAttempt PCI if:
> 1 clinically relevant CTOInexperienced operator (<1000 PCI)Other cardiac s rger indications
• CABG contraindicated• Patient/family and cardiac
surgeon agree on PCIOther cardiac surgery indications
MVD With High SYNTAX Score without any of above unfavorable features:
CABG favored, but PCI is a good alternativeespecially if FFR-guided
A “ functional SYNTAX Score “ ( FFR ) can be more appropriate to select patients with MVD for a moreappropriate to select patients with MVD for a more appropriate treatment option
