BackgroundIn patients with coronary artery disease, stress-redistribution-reinjection thallium scintigraphy provides important information regarding myocardial ischemia and viability.Although both reversible and mild-to-moderate irreversible thallium defects retain metabolically active, viable myocardium, we hypothesized that stress-induced reversible thallium defects may better . I was diagnosed with ejection fraction rate 75%, very small reversible apical defect with myocardium at risk. It uses radioactive tracers that are injected into the blood to produce pictures of your heart. June 21, 2018. 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." The left ventricular intramural pressure is greatest near the endocardium and least near the epicardium. The patches record the heart's rhythm. The entire perfusion scanning takes around four hours to be completed. . Reversible Myocardial Ischemia is one of the common diseases that usually cause atherosclerosis of the coronary artery, infrequent etiologies, and myocardial microcirculation disturbance. An imbalance can be detected through dynamic electrocardiographic features or reversible perfusion defects during stress testing. Google Scholar. Regional thallium uptake in irreversible defects: Magnitude of change in thallium activity after reinjection distinguishes viable from nonviable myocardium. Test result. 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.

Article This cookie is set by GDPR Cookie Consent plugin. what does this mean? Dilsizian V, Freedman NMT, Bacharach SL, Perrone-Filardi P, Bonow RO. One of the key advantages of positron emission tomography (PET) over SPECT is that it offers validated tracer kinetic models for quantifying absolute myocardial blood flow.14,15 PET permits reliable attenuation and scatter correction based on either external transmission sources or on CT images thereby enabling quantification of absolute myocardial blood flow in the heart, which represents the mean transmural myocardial blood flow. Libby P, et al., eds. If the scan is normal at rest but abnormal following exercise (a reversible perfusion defect), then the heart isn't . It is not: normal, reversible ischemia means that there are areas of your heart that do not get enough blood flow under stress, but do get enough flow at rest. When both viable myocardium and scarred myocardium are present, the defect may be characterized as mild-moderate fixed, which connotes non-transmural infarction, and can also be seen after percutaneous coronary intervention in the setting of acute coronary syndrome (Table1).

Perfusion scanning showed mild and moderate fixed defects in the mid-inferior and basal inferior walls and septum indicating infarction. This time I informed the sonographer performing the test to pay special attention to precisely measuring the mid and basal portions of the ventricular septum segments and to measure the development of obstruction within the left ventricle by Doppler immediately post-stress. There are 2 techniques for MPI: single photon emission computed tomography (SPECT) and positron emission tomography (PET). However, it needs to be placed in the patients clinical context. It is now well established in the literature that while both reversible and mild-to-moderate fixed myocardial perfusion defects retain metabolically active, viable myocardium, stress-induced reversible perfusion defects will more accurately predict recovery of regional function after revascularization (Figure1).6,7 Although regions with mild-to-moderate fixed perfusion defects indeed retain viable myocardium, the mere presence of viable myocardium does not necessarily translate into recovery of function after revascularization.
