Implication
Placing bypass grafts across noncollateralized occlusions to infarct zones may increase post-CABG VT risk; leaves open whether grafting strategy modification reduces events.

Outcome
Development of sustained ventricular tachycardia (VT)hard clinical
The incidence of new-onset sustained VT after CABG is 3.1%, and it is strongly predicted by placing a bypass graft across a noncollateralized total occlusion supplying an infarct zone.
