How to FFR when the FFR wire can't pass

Fractional flow reserve (FFR) wires are notoriously difficult to maneuver. We discuss a quick and simple technique to pass FFR wires across difficult lesions with a workhorse already in place using aspiration thrombectomy catheters. The same technique can be used to pass buddy wires in tough vessels. Chao-Wei Hwang, M.D., Ph.D. Johns Hopkins University School of Medicine Cardiac Cath Lab, Frederick Health Hospital
