Cath Report:

Left Main Trunk: Normal caliber, patent

Left Anterior Descending Artery: 100% acute occlusion of mid LAD

Left Circumflex Artery: Moderate stenosis in mid LCx. OMB1 is large and patent. OMB2 is large and has moderate proximal disease.

Right Coronary Artery: Dominant. Mid RCA has long diseased segment with upto 80% stenosis. Distal RCA has mild luminal irregularities.


1. Acute 100% occlusion of mid LAD (culprit vessel)

2. Moderate stenosis of mid LCx and proximal OMB2

3. Severe mid RCA stenosis.


1. Successful PCI of mid LAD acute occlusion


  • Anteroseptal MI
    • ECG findings in V1-V3
      • ST segment elevation with Q wave formation in the precordial leads (V1-6) ± the high lateral leads (I and aVL)
      • Precordial leads
        • Septal leads = V1-2
        • Anterior leads = V3-4
        • Lateral leads = V5-6
    • Site of LAD occlusion (proximal versus distal) predicts both infarct size and prognosis.
    • Proximal LAD / LMCA occlusion has a significantly worse prognosis due to larger infarct size and more severe hemodynamic disturbance.
