Figure 2: (a) Pulse Doppler assessment of the proximal left main coronary artery with abnormal flow noted in both systole and diastole with peak systolic velocity of around 2 m/s suggestive of severe stenosis. (b) PW Doppler showing normal antegrade flow in the left main coronary artery during diastole above the baseline
