The primary efficacy outcome was the composite of no occlusion in the treated segment assessed at serial duplex ultrasound examinations or no reintervention needed to maintain patency within 6 months. Secondary outcomes, including Villalta score, quality of life, and safety outcomes, were also assessed.

This case was provided by Spencer Schwartz, an outstanding paramedic at Hennepin EMS who is on Hennepin EMS's specialized "P3" team, a team that receives extra training in advanced procedures such as RSI, thoracostomy, vasopressors, and prehospital ultrasound. Takotsubo is a sudden event, not one with crescendo angina.

The cardiologist called this 20% stenosis. Fortunately, this operator used intravascular ultrasound (IVUS). NOTE: For review of 20 cases of "Swirl" vs Swirl "Look-Alikes" — Check out the October 15, 2022 post in Dr. Smith's ECG Blog. An angiogram is a " lumenogram " and does not "see" the extraluminal plaque.

We report our experience validating this large animal model for translational and preclinical research.Methods3 animal experiments were performed at the UCLA TRIC laboratory between 02/2022 and 10/2022. The sheep were anesthesitized and handled under approval of the Animal Research Committee at UCLA (protocol ARC 2020‐19).

During medical school, one of the classic bedside exam questions we get is how to differentiate the valve issues of aortic stenosis and mitral regurgitation, which produce similar but different murmurs when you listen with a stethoscope. “How can you tell the difference between aortic stenosis and mitral regurgitation at the bedside?”

His response: “subendocardial ischemia. Anything more on history? POCUS will be helpful.” Left main? 3-vessel disease?

A lower extremity arterial ultrasound revealed elevated velocities in the right proximal superficial femoral artery. Dr. Dormu performed an aortogram of the bilateral lower extremity with bilateral iliac runoff, which revealed a 90% stenosis of the right superficial femoral artery and 100% occlusion of all three tibial vessels.

A bedside ultrasound should be done to assess volume and other etiologies of tachycardia, but if no cause of type 2 MI is found, the cath lab should be activated NOW. In addition, the top left blue arrow indicates a section in the LAD with a severe stenosis, likely the culprit for the prior L A D occlusion which has since recanalized.

So we did a bedside cardiac ultrasound. I’ve reviewed My Take on the ECG diagnosis of RVH on a number of occasions in Dr. Smith’s ECG Blog ( See My Comment at the bottom of the page in the March 6, 2022 and September 1, 2020 posts , to name just 2 ). That condition is tricuspid stenosis, which is rare.

I suspect pulmonary edema, but we are not given information on presence of B-lines on bedside ultrasound, or CXR findings. Smith : "decompensation" of aortic stenosis might have initiated this entire cascade. What "initiates" the aortic stenosis cascade? Or I suspect that there is OMI simultaneous with another pathology.
