Successful drug-eluting stent placement opening up 95% mid RCA stenosis to 0% residual Nonobstructive left system disease. We have shown many examples of this on this blog. Emergency department Code STEMI patients with initial electrocardiogram labeled ‘normal’ by computer interpretation: a 7-year retrospective review.

LAD and D1 were stented, but flow unfortunately could not be well restored despite efforts (they list the post intervention TIMI flow still as 0). And they of course activated the cath lab immediately, where he was found to have acute thrombotic occlusion (TIMI 0) of the proximal LAD, as well as embolic D1 occlusion. Am J Emerg Med.

Because: 1) He has been reading this blog for a long time. The attending provider wrote “Agree with electrocardiogram interpretation”. All three lesions had TIMI 2 flow prior to stenting. This is an RAO cranial projection of the left coronary vessels after thrombectomy and stenting. Normal EKG”. Normal ECG.

He was found to have a 100% circumflex lesion for which a bare metal stent was placed. Laurence Katz and Jonathan Jones Safety of Computer Interpretation of Normal Triage Electrocardiograms (pages 120–124). It is not subtle any more. Interventional cardiology was consulted and patient was taken to the cath lab. References : 1.

The OM-1 was opened and stented, then the LAD was stented 3 days later. The LAD had a 75% proximal lesion that by fractional flow reserve was hemodynamically significant. So there was 3-vessel disease, but with an acute posterior STEMI. The acute infarct-related artery was off the circumflex and the affected wall was posterior (STEMI).

The culprit lesion was opened and stented. Below is the post -PCI electrocardiogram.
