Reversible Perfusion Defects
Collateral Insufficiency
Case history/ Imaging data
SPECT myocardial perfusion testing was performed using Tc-99m-Sestamibi. Images representing myocardial perfusion were obtained at rest and peak stress .

Stress protocol
  • Treadmill / Bruce
    • Duration of stress
  • 12 min
    • Peak heart rate (85%)
  • 85 --> 150 (85%=133)
    		•
    Systolic BP (basal --> peak)
  • 150 --> 160
    • Double product (peak rate x BP)
  • 24,000
    		•
    Reason for termination
  • Dyspnea. Typical chest pain
    • ECG findings
  • 1 mm ST depression
    		•
