What is a fixed defect in the heart?

What is a fixed defect in the heart?

On the other hand, perfusion abnormalities that are seen both on stress and rest myocardial perfusion images, are termed fixed or irreversible defects, which most often suggests an area of prior myocardial infarction, particularly if the defect is severe (with the exception of hibernation or repetitive stunning).

What is a fixed perfusion?

A fixed defect is a perfusion defect present at stress and rest. Primary differential for a fixed defect includes scarring from infarction, chronically ischemic areas called hibernating myocardium, or attenuation.

What is a mild fixed perfusion defect?

Non-reversible defect (fixed) shows no significant changes in activity between post-stress or rest images. Severe fixed defect most likely represents scarring or fibrosis from prior MI, but a mild or moderate fixed defect may indicate hibernating myocardium or prior nontransmural MI.

What is a reversible defect?

A coronary stenosis is detected when a myocardial segment takes up the nuclear tracer at rest, but not during cardiac stress. This is called a “reversible defect.” Scarred myocardium from prior infarct will not take up tracer at all and is referred to as a “fixed defect.”

What is a reversible heart defect?

Is the photopenia of the heart reversible?

No definite significant reversible stress-induced ischemia. 2. Small area of mild completely reversible photopenia along the distal anterior wall and apex, demonstrating normal kinetics, and therefore, probably artifactual. However, follow-up is recommended. 3) Normal LVEF of 78% .

What do you need to know about photopenia?

What is the photopenia, not sure what this means. They are also sending me to a gastroenterologist for follow-up as nothing shows on Abdominal CAT scan. I have gained 11 pounds in less than 10 days and feel like I’m 7 mos pregnant. No Ob-GYN problems.

What does fixed apical defect in the heart mean?

As applicable, a fixed apical defect (scar tissue, irreversible/permanent damage) would indicate no blood flow (no perfusion) to an area there, typically caused by heart attack (myocardial infarction, MI), due to coronary artery disease/atherosclerosis.
