[Expanded indication of percutaneous transluminal coronary angioplasty to the infarcted zone--using thallium-201 exercise scintigram after rehabilitation].

In some cases of old myocardial infarction (OMI), left ventricular wall motion was improved after revascularization, though viability of the infarcted myocardium was not detected by left ventriculography (LVG) and exercise thallium-201 myocardial scintigraphy (EX-Tl). So to obtain more correct information of the viability, EX-Tl was performed again after ergometer rehabilitation for an OMI patient whose myocardial viability of the infarcted zone could not detected by LVG and EX-Tl. Incomplete fill in was showed in the EX-Tl after rehabilitation. So percutaneous transluminal coronary angioplasty (PTCA) was performed. Left ventricular wall motion was improved after three months. EX-Tl after rehabilitation is useful to evaluate the viability that could not detected by LVG and EX-Tl.
