A transthoracic echocardiogram showed an LV EF of less than 15%, critically severe aortic stenosis , severe LVH , and a small LV cavity. The aortic valve in this example also had critical stenosis by Doppler The patient continued to be hemodynamically unstable with poor cardiac output and very high LV filling pressures.

Background:Myocardial infarction with nonobstructive coronary artery disease (MINOCA) is a special syndrome with clear evidence of myocardial ischemia, but no clear stenosis of coronary artery imaging sign. Circulation, Volume 150, Issue Suppl_1 , Page A4143007-A4143007, November 12, 2024.

There is ventricular hypertrophy in the absence of abnormal loading conditions, such as aortic stenosis, or hypertension, for example – of which the most common variant is Asymmetric Septal Hypertrophy. There is LBBB-like morphology with persistent patterns of subendocardial ischemia. References Naidu, S. Tower-Rader, A.

American Heart Journal 170(6):1255-1264; December 2015. So the patient was taken for emergent cath, showing: Culprit artery: LAD (100% stenosis, TIMI 0) requiring thrombectomy and stent. EKG shown here: LAFB with no clear signs of OMI or ischemia. Derivation in LBBB: --> Smith SW. No labs were performed.

The patient was started on heparin for possible NSTEMI vs demand ischemia. Smith : "decompensation" of aortic stenosis might have initiated this entire cascade. What "initiates" the aortic stenosis cascade? increasing stenosis, ischemia, volume changes, increased blood pressure, atrial fibrillation, etc.)
