Abstract Introduction:The assessment of myocardial viability in patients presenting coronary artery disease (CAD) and associated ventricular dysfunction is an important tool for selecting patients with ischemic cardiomyopathy who may benefit from myocardial revascularization. Case review: This is a hypertensive patient in regular use of medications and in follow-up at outpatient since 2011. He had an ischemic coronary event in 2013. Cardiac catheterization showed coronary lesions in the left anterior descending artery (LAD) and right coronary artery (RCA), which were treated with stents. The patient began to develop dyspnea on moderate exertion and undergoing myocardial scintigraphy with 99m Tc-sestamibi, which showed ischemia in the left ventricular anterior wall. Echocardiography showed no ventricular dysfunction. He was treated with optimization of medications. However, in the scintigraphic control examination, the ischemic area showed up as persistent hypoperfusion. A new cardiac catheterization showed stent restenosis. For evaluation of myocardial viability, we used a scintigraphy with thallium-201 that showed no tracer uptake in the left anterior descending artery territory. As the patient remained symptomatic, a new attempt of myocardial viability research with 18 F-Fluorodeoxyglucose was performed. This showed a viable left ventricular anterior wall. Conclusion: The report confirms the greater sensitivity of Positron-emission tomography/computed tomography with 18F-Fluorodeoxyglucose in detecting a viable myocardium.Descriptors: Radionuclide Imaging; Myocardial Perfusion Imaging; Thallium; Technetium Tc 99m Sestamibi; Fluorodeoxyglucose F18.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
