Correct!
The PET findings reveal a normal resting myocardial perfusion. There is a marked stress induced worsening of perfusion (arrows) in the entire inferior, interolateral, and inferoapical regions. PET findings suggest the presence of severe ischemia involving a large area of the myocardium in the distribution of a large dominant LCx or both LCx and RCA.
The polar maps confirm that the stress induced abnormalities are dominant in the LCx, possibly extending into the territory of the RCA.
To review the medical images, select one of the following:
Follow-Up
Coronary angiography on 1/12/93:
- 95% proximal stenois of a large, dominant LCx; normal LAD and RCA
Coronary angiography on 1/20/93:
- Normal LCx
