Category 1 : Sudden narrowing of a coronary artery due to ACS (plaque rupture with thrombosis and/or downstream showering of platelet-fibrin aggregates. It’s judicious, then, to arrange for coronary angiogram. Supply-demand mismatch (non-occlusive coronary disease, or exacerbation of preexisting flow insufficiency) a.

During angiogram in the cath lab, the patient suffered two episodes of ventricular fibrillation for which he was successfully defibrillated. Angiogram showed a culprit lesion of 100% stenosis to the right coronary artery and 100% stenosis of the right posterior descending artery, both with TIMI 0 flow.

The diagnostic coronary angiogram identified only minimal coronary artery disease, but there was a severely calcified, ‘immobile’ aortic valve. Aortic angiogram did not reveal aortic dissection. Oxygen supply is determined by: 1) oxygen carrying capacity, 2) O2 saturation, and 3) Coronary flow.

History sounds concerning for ACS (could be critical stenosis, triple vessel), but differential also includes dissection, GI bleed, etc. See this case: what do you think the echocardiogram shows in this case? 2 cases of Aortic Stenosis: Diffuse Subendocardial Ischemia on the ECG. His response: “subendocardial ischemia.

More troponin values were measured at the cardiac center: 2327- 267 ng/L 0821- 355 ng/L 1108- 305 ng/L An echocardiogram on day three of the patients admission showed an ejection fraction of 46% with abnormal basal inferior and basal lateral segments, and severe aortic stenosis. What "initiates" the aortic stenosis cascade?
