Angina Stenosis Ultrasound

SEPTEMBER 18, 2024
Bedside cardiac ultrasound with no obvious wall motion abnormalities. Because the pathologist determines the degree of stenosis by dividing the lumen area by the total area, the degree of stenosis will be overestimated. The angiographer uses a denominator that is too small, thereby underestimating the degree of stenosis.

Bedside ultrasound with no apparent wall motion abnormalities, no pericardial effusion, no right heart strain. Patient is pain free and clearly has Wellens' syndrome: 1) pain free episode following an episode of angina, typical Pattern A (biphasic, terminal T-wave inversion with an initial upsloping ST Segment) findings, preserved R-waves.

Six-month angiographic follow-up with optical coherence tomography and intravascular ultrasound was available in 74 patients. Intravascular ultrasound findings showed no difference in mean vessel area at the lesion site from baseline to follow-up in the scoring balloon group (16.82.9 versus 6.31.5 mm2;P=0.65), mean scaffold area (7.81.5

Thus, the patient does not (yet) get a formal diagnosis of MI and must be called unstable angina unless further troponins return above the 99th percentile. On the basis of unresolved angina, cardiology decided to perform rescue PCI. The LAD has diffuse disease with a few areas of moderate stenosis but no flow-limiting lesions.

If it is angina, lowering the BP with IV Nitroglycerine may completely alleviate the pain and the (unseen) ECG ischemia. Or is it a very tight stenosis that does not allow enough flow to perfuse myocardium that has a high oxygen demand from severely elevated BP? The ST depressions in I and aVL have resolved.

link] A 62 year old man with a history of hypertension, type 2 diabetes mellitus, and carotid artery stenosis called 911 at 9:30 in the morning with complaint of chest pain. This is written by Willy Frick, an amazing cardiology fellow in St. He described it as "10/10" intensity, radiating across his chest from right to left.
