A study of CT-guided CABG showed better early outcomes of coronary artery bypass grafting (CABG) in patients with multivessel coronary artery disease (CAD). Surgery was guided by CT-based fractional flow reserve (FFR). The results support early enthusiasm for this approach. The study is ongoing as part of a trial version with the identifier NCT03894423. Researchers perform cardiac CT before and after CABG. They measure absolute changes in myocardial perfusion as a functional outcome of surgery. The presentation took place at a meeting in New Orleans, according to MedPage Today.
