Acquisition is clean
Mild spectral broadening detected near peak diastole. Acceptable for measurement; consider a brief breath hold for the next acquisition to tighten the envelope.

Clinical Insights
High-confidence distal LAD waveform with stable diastolic dominance across 4 cardiac cycles.
Coronary flow with normal velocities and no significant retrograde flow, consistent with normal coronary hemodynamics.
Mild spectral broadening at peak diastole — does not change measurement validity. Beat-to-beat PDV variance 1.8%. No arrhythmic beats rejected.
