Doppler velocity may track PTCA hemodynamic effects; leaves open need for randomized validation before clinical adoption.
Does Doppler flow velocity measurement accurately reflect hemodynamic changes before and after PTCA in patients with coronary stenoses?
Doppler-tipped guidewires can detect significant changes in pre- and post-stenotic coronary flow velocity, offering a method to estimate the hemodynamic success of PTCA.
Dill et al. (1994) studied this question.
