This causes more energy loss and less energy is recovered as pressure distally. These effects cause an increase in both Doppler and catheter-derived gradients with less pressure recovery. The impact of LVOT diameter on Doppler-­ derived Pmean was further elucidated in a recent Doppler study of about 10,000 patients.
