Abstract
IdentifYing areas of myocardium with depressed but
potentially reversible contractile function may bear important
significance in the therapeutic strategy and perhaps the
prognosis of patients with coronary artery disease and left
ventricular dysfunction (Rallimtoola, 1989). Consequently,
the non-invasive assessment of dys-synergic but viable
myocardium, which may contribute to the overall
improvement m left ventricular function after revascularization;
has generated great interest among
cardiologists and cardiac surgeons (Brundage eta/., 1984).
Among the several techniques used for this purpose, Tl-
20 I scintigraphy (using rest-redistribution or stressredistribution
reinjection protocols) has been shown to be a
useful method, largely based on the observation that the
presence of thallium uptake’ in a myocardial region with
depressed systolic function correlates with contractile
improvement aticr rcvascularization (Ragosta eta/., 1993).
Sestamibi unagmg IS commonly believed to
underestimate viability; however its optimal nnaging
characteristics are not completely explored. Gated-SPECT
permits assessment of an original marker of viability; which is
the radionuclidc myocardial wall thickening (RMWT),
