The patient underwent a dipyridamole/rest myocardial perfusion gated SPECT study with 99mTc-MIBI Teaching points
Myocardial perfusion imaging is useful for identifying multivessel disease, since most patients have perfusion abnormalities indicative of ischemia.
In few cases, balanced ischemia can produce “normal” perfusion images but frequently showing myocardial stunning with transient LV dilation and lower post-stress LVEF.
High risk studies indicate the need for aggressive management.
