Characterized by a narrowing of the small vessels of the fingers and toes, Raynaud disease exemplifies a perfusion defect. I had a Nuclear Stress Test in April 2022. An atrial septal defect (ASD) is a hole in the wall (septum) between the two upper chambers of your heart (atria). 6 What does the term anteroapical perfusion defect mean? Never disregard the medical advice of your physician or health professional, or delay in seeking such advice, because of something you read on this Site. New to the MedHelp community. HHS Vulnerability Disclosure, Help A coronary stenosis is detected when a myocardial segment takes up the nuclear tracer at rest, but not during cardiac stress. Ischemia can also be acute, due to a sudden reduction in blood flow, or chronic, due to slowly decreasing blood flow. The damaged areas may be called cold spots or defects. A stress myocardial perfusion scan assesses blood flow to the heart muscle when it is stressed. The sensitivity, specificity and accuracy of cardiac imaging with single-photon emission computed tomography (SPECT) is between 44 percent and 70 percent depending on the blood vessels involved. The existence of reversible perfusion defects in the anteroseptal region in most of the patients suffering from left bundle branch block (LBBB) on MPI following physical exercise as stressor is well documented.

Perfusion defect after exercise, BUT NOT at rest (reversible defect) There is some degree of blockage in a coronary artery that interferes with the blood flow to the heart muscle. The condition is present at birth (congenital). A perfusion defect is an SMALL area of the heart with diminished blood flow under stress. Reversible means that it was not see at rest so it can be reversed as it is not always there which could indicate dead heart muscle from a previous MI, but only under stress. This can indicate a blockage.

If your stress test results suggest that you might have coronary artery disease or show an arrhythmia, your doctor will use the information to develop a treatment plan. Stress-induced perfusion abnormalities in regions that exhibit normal perfusion at rest are termed reversible perfusion defects, and such regions represent viable, ischemic tissue with blunted coronary blood flow reserve. Areas that are damaged or dont have good blood flow do not absorb the tracer. Probably you have had a myocardial infarction (heart attack), apparently a large one. All Rights Reserved.

An abnormal result in both phases of your stress test is an indication that your hearts blood flow is poor, regardless of your exertion level. A mycocardial perfusion scan is an imaging study that shows how well blood flows through the heart muscle. It happens when the brains blood vessels become narrowed or blocked, causing severely reduced blood flow (ischemia). Analytical cookies are used to understand how visitors interact with the website.

Although patients with a permanent ventricular pacemaker have a similar conduction abnormality as patients presenting with a LBBB, most of the defects found on MPI imaging in this patient population (in up to 78% of patients with a normal coronary angiogram that area continuously paced) are localized in the inferoposterior (71%), apical (50%) and inferoseptal (28%) wall; coronary flow velocities in the left anterior descending (LAD) and dominant coronary artery and coronary flow reserve are also significantly lower when compared to a control group. Some small atrial septal defects close during infancy or early childhood. A coronary stenosis is detected when a myocardial segment takes up the nuclear tracer at rest, but not during cardiac stress.

The demand for oxygen in the cardiac muscle are higher What your mentioning is perhaps occlusion of the arteries in the lower part of your heart. Pulmonary embolism occurs when a clump of material, most often a blood clot, gets wedged into an artery in your lungs. Its typically indicative of one of two things. There is poor blood flow to that area of the heart. This is typically seen as a reversible perfusion defect, in that blood flow is insufficient to meet exercise demand and the defect appears with exercise or some other stress.
