Scintigraphy assessment of ischemic myocardial viability in patients with post-infarction left ventricular aneurysm

The study included Jeans 15patients with coronary heart disease (CHD), post-infarction cardiosclerosis, and chronic left ventricular (LV) aneurysm.All patients underwent interventional myocardial revascularization and Dor aneurysmectomy.Myocardial scintigraphy with 99mTc-MYOVIEW was performed at baseline (during nitroglycerine test and at rest), and 3-4 weeks after revascularization (at rest).According to baseline scintigraphy at rest data, 35 % of the segments were hypoperfused, and in 20 % the agent did not accumulate.After sublingual nitroglycerine administration, hypo- and non-perfused segment percentage reduced to 24 % and 11 %, respectively, after revascularization - to 24 % and 11 %.

Single-photon emission computed tomography read more with 99mTc-MYOVIEW, combined with sublingual nitroglycerin test, identifies viable myocardial zones in post-infarction LV aneurism area and might be used for predicting post-revascularization LV function recovery.
