Left ventricular afterload reduction is essential to decrease the trans-se ptal pressure gradient and thus decrease shunt volume, making a larger proportion of the blood flow from the left ventricle through the aortic valve. Older patients and those with poor right ventricular function often fall into this group.

Patients with documented STEMI, left ventricular thrombus, mechanical mitral or aortic valve replacement were excluded. ICD 10 codes were used to identify patients with documented a fib. Procedure ICD codes were used to identify patients that underwent percutaneous LAAO. 5,661 underwent percutaneous closure.

Look at the aortic outflow tract. Clinical Course The paramedic activated a “Code STEMI” alert and transported the patient nearly 50 miles to the closest tertiary medical center. The diagnostic coronary angiogram identified only minimal coronary artery disease, but there was a severely calcified, ‘immobile’ aortic valve.

The next morning the patient went for his routine echocardiogram, where the operator noticed a dilated aortic root at 5.47 cm with severe aortic insufficiency. The team was notified and they ordered a stat aortagram which showed type A aortic dissection from the aortic valve to the iliacs. Pericarditis?

But limitation of this ST elevation to a single lead is not consistent with any distribution of a STEMI. The plan was to proceed as soon as possible with aortic valve replacement. This patient needed prompt aortic valve replacement. Then there is the significant ST elevation we see in lead V1.

The provider contacted cardiology to discuss the case, but cardiology "didn't think it was a STEMI, didn't think he needed emergent cath." JAMA 2000) showed that 1/3 of patients with STEMI, and 1/3 of patients with NSTEMI, present without chest pain. The whole paradigm is literally called "STEMI" vs. "NSTEMI." Canto et al.

Supply-demand mismatch can cause ST Elevation (Type 2 STEMI). Also see these posts of Type II STEMI. An EKG from a year prior was available for comparison: The ED physician noted Initial EKG here read by the computer as a STEMI, however, there is a very poor baseline and a lot of artifact.
