Comparison of wire-based hyperaemia-induced fractional flow reserve (FFR) and angiography-based vessel fractional flow reserve (vFFR) in patients undergoing physiological assessment of coronary lesions.
OBJECTIVE While pressure-wire based fractional flow reserve (FFR) is considered the gold standard for evaluating coronary lesion significance, its use in daily clinical practice remains limited.Angiography derived vessel based FFR (vFFR) offers a promising alternative, without the need for pressure wires or hyperaemia...
