Example of CFVR measurement by Doppler TTE. Lower pictures show measurement at rest. Upper pictures show measurement during hyperaemia. Pictures to the left show the colour Doppler visualisation of the LAD. Pictures to the right show the pulsed wave Doppler measurement of the diastolic peak coronary flow velocity (CFV). Coronary flow velocity reserve (CFVR) of this participant was 2.86 (corresponding MFRLAD was 2.57)
