TCT-230 Myocardial Ischemia Is Present and Mostly Reversible in Patients With a Chronic Total Occlusion and a Viable Perfusion Territory: The DISTAL CTO Study
JOURNAL OF THE AMERICAN COLLEGE OF CARDIOLOGY(2019)
摘要
The highest benefit of revascularization is found in patients with very low fractional flow reserve (FFR). In chronic total occlusion (CTO) patients, instant wave-free ratio (iFR, Philips) may be more appropriate to evaluate ischemia as it does not require maximal microvascular vasodilation, which
