Aneurysm Ischemia Stenosis 
Circulation
NOVEMBER 13, 2024
Kawasaki disease (KD), an acute self-limited febrile illness that primarily affects children <5 years old, is the leading cause of acquired heart disease in developed countries, with the potential of leading to coronary artery dilation and coronary artery aneurysms in 25% of untreated patients.

The old ECG has a Q-wave with persistent ST elevation in lead III, and some reciprocal ST depression (typical for aneurysm morphology). This is "Persistent ST elevation after previous MI" or "LV aneurysm morphology". LV aneurysm is very different for inferior vs. anterior MI. The patient had a critical LAD stenosis.

T-wave inversion in V2 is inconsistent with early repol, and is typical of posterior ischemia. In addition, there is ST depression, diagnostic of ischemia, in V3-V6. It showed a 99% stenosis in the RCA, and proximal to a posterolateral branch. A coronary aneurysm was found. mm of ST elevation in inferior leads.

The EKG is diagnostic of acute inferior, posterior, and lateral OMI superimposed on “LV aneurysm” morphology. Whether these EKGs show myocarditis, a normal variant, or something else, they are overall not typical of transmural ischemia of the anterior or high lateral walls. Patient 2 , EKG 1: What do you think?

Prior ECG available on file from 2 months before: We do not know the clinical events happening during this ECG, but there is borderline tachycardia, PVCs, and likely some evidence of subendocardial ischemia with small STDs maximal in V5-6/II, slight reciprocal STE in aVR. QS waves from V2-V5 consistent with LV aneurysm morphology.

An elderly patient with a ruptured abdominal aortic aneurysm: Formal ECG Interpretation (final read in the chart!) : "Inferior ST elevation, lead III, with reciprocal ST depression in aVL." Is there likely to be fixed coronary stenosis that led to demand ischemia during pneumonia? --Was What do you think?

This ECG is all but diagnostic of subepicardial ischemia of the anterior, lateral, and inferior walls, most likely due to Occlusion MI (OMI), probably of the LAD. They found an acute lesion of the LAD at the site of the prior stents, including 70% proximal LAD lesion and 95% mid-LAD stenosis with TIMI 3 flow at the time of cath.
