Implication

Case report reveals normal microvascular flow reserve despite slow flow in an angina patient, suggesting coronary ectasia rather than small vessel disease causes dye progression delay.

Key Points

To investigate the underlying physiological cause of coronary slow dye progression in an individual presenting with angina pectoris without evident arterial stenosis.
Assessed an individual with recent-onset chest pain using diagnostic coronary angiography.
Conducted intracoronary Doppler measurements to quantify blood flow velocity, coronary flow reserve, and calculated coronary blood flow.
Demonstrated marked reduction in coronary blood flow velocity on intracoronary Doppler despite the absence of significant coronary artery stenosis.
Recorded normal coronary flow reserve and calculated coronary blood flow within normal physiological limits.
Identified prominent coronary artery ectasia, indicating that epicardial vessel enlargement rather than microvascular impairment accounts for delayed dye progression.
