Simultaneous intracoronary pressure and Doppler guidewires to assess coronary stenosis: if one is enough, are two too much?
We report a potential source of erroneous estimation of stenosis severity by pressure guidewire assessment. Simultaneous introduction of pressure and Doppler guidewires can lead to an overestimation of stenosis pressure gradient in the evaluation of intermediate stenosis.
