TCT-310 Peripheral pressure wire measurement of the below-the knee arteries in critical limb ischemia: validation with angiography and Laser Doppler measurements

Background The aim of the study was to assess the correlation between non-invasively versus invasively measured parameters by pressure wire during rest and after maximal hyperemia (peripheral fractional flow reserve (pFFR)) before and after below-the-knee angioplasty. Routine quantitative angiograph...

Description
Summary:Background The aim of the study was to assess the correlation between non-invasively versus invasively measured parameters by pressure wire during rest and after maximal hyperemia (peripheral fractional flow reserve (pFFR)) before and after below-the-knee angioplasty. Routine quantitative angiography, pressure wire (pressure gradient, resting and stress FFR), laser Doppler (Perfusion unit (DPU), transcutaneous oxygen (TcO2)) and duplex ultrasound measurements were performed before and after angioplasty.
