ECG in LMCA Stenosis

All About Cardiovascular System and Disorders

Such a pattern is consistent with significant left main coronary artery stenosis. Angiography done after initial stabilization showed severe stenosis of distal left main coronary artery. Clinical evaluation and X-Ray chest showed features of pulmonary edema.

Diffuse Subendocardial Ischemia on the ECG. Left main? 3-vessel disease? No!

Dr. Smith's ECG Blog

A transthoracic echocardiogram showed an LV EF of less than 15%, critically severe aortic stenosis , severe LVH , and a small LV cavity. The patient was transported to the CCU for further medical optimization where a pulmonary artery catheter was placed. If you see this, you should Doppler the valve.

which would suggest reduced rates of major adverse cardiac events with coronary artery bypass grafting." 2 days later This is a typical LVH pattern, without ischemia Patient underwent 4 vessel CABG.

Pulmonary edema, with tachycardia and OMI on the ECG -- what is going on?

Dr. Smith's ECG Blog

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.)

Are there hyperacute T-waves? And how can we know?

Dr. Smith's ECG Blog

Watch what happends as the heart recovers from its episode of ischemia. Angiogram: Severe two-vessel coronary artery disease of a left dominant system including 70 to 80% stenosis involving the distal left main/bifurcation. The ECG shows inferior ischemia. Are the T-waves in leads I and II hyperacute? Hard to tell.
