Abstract
Myocardial viability categorized into 5 categories such as normal myocardium, reversibly ischaemic myocardium, peri infarct ischaemic myocardium, stunned myocardium, hiberna ng myocardium. In this era of mul modality and mul parametric imaging heave with a spectrum of imaging modali es to choose from, nuclear imaging delivers best results as far as Viability imaging is concerned as Viability is a physiological phenomenon that can be imaged directly with a physiological imaging modality (SPECT AND PET). Anatomical modali es “claim” to assess viability but with limited results. Accurate pre-op assessment can deliver best results for pa ent standing on a
“T” junc on of medical vs. interven onal management, thus the dilemma resolved and the clinician conï¬ dently can go ahead with the right choice of therapy. If revascularisa on is contemplated and viable myocardium present the resultant beneï¬ t of improvement in quality of life can be conï¬ dently arrived at in a preopera ve scenario. Viable myocardium is located anatomically in the sub epicardial layers of the le ventricular wall, above the infarct in the sub endocardial layers in the distribu on of a steno c coronary artery. Thallium 201, 99m Tc SESTA MIBI, 18-F FDG are few radio tracers used to determine myocardial viability, the “gold standard” being 18 F FDG according to literature.
