Elsewhere at EuroPCR 2018, Dr. Serruys presented the results of the, which randomized six pairs of heart teams – each comprising an interventional cardiologist, surgeon, and radiologist – to collectively assess and plan revascularization strategies for 223 patients with left main or triple-vessel CAD. One heart team in each pair was provided with a patient’s noninvasive CTA and FFR results, while the other team was given only the results of conventional angiography.
“There was almost perfect agreement between the heart teams on their decisions,” according to Dr. Serruys. “We were impressed that the surgeons were enthusiastic about the prospect of operating based on multislice CT alone.
On the basis of this evidence that heart teams found, the noninvasive assessment to be acceptable, he and his coinvestigators are organizing a multicenter trial to assess the feasibility and safety of the fully noninvasive stratification, compared with conventional angiography and invasive physiologic assessment of lesions. The primary safety endpoint will be the 1-month patency of bypass grafts.
The multislice scanner used in the SYNTAX III Revolution trial was the General Electric Revolution CT scanner, which enables imaging of the heart during a single heart beat. But Dr. Serruys said most of the big medical imaging companies with an eye to the near future are now developing multislice scanners specifically for the heart.
