  • found to be in VF arrest 2/2 inferior STEMI.
  • 7 rounds epi, shocks; also given amio and lidocaine. Post-arrest ECG w/ STE in inferior leads, RBBB, and LAFB.

      Left Main: Normal
      Left Anterior Descending: Appeared to be flush occluded at takeoff, no visible stump, not filling via collaterals.
      Left Circ: Mild Luminal Irregularities less than 30%
      RCA: Large ectatic vessel, difficult to enagage secondary to anterior and inferior take off. Extremely tortuous mid vessel. 70% proximal lesion. Totally occluded mid vessel.PROCEDURAL COMMENTS:

His LAD appeared to be ostially occluded on angiography; however, the anterior wall appeared to move well on echo. He underwent coronary CT angiogram to further evaluate, revealing “extensive calcified plaque in the LAD, RCA and left circumflex coronary arteries. I

      • study extremely limited for evaluation of stenosis/luminal narrowing…
        • LAD arises directly from the aortic root just above the sinus of Valsalva and has a sharp acute course at the origin between the aorta and main pulmonary artery.”
        • Lcx arises separately from the left coronary cusp
        • EF 50%
