    We describe our experience from the first 30 patients treated with percutaneous transluminal coronary angioplasty (PTCA) in the Cardiologic Department P, Gentofte Hospital. The main purpose was to evaluate the value of thallium scintigraphy performed before and three months after PTCA. After PTCA, 23 (77%) had no angina and 22 (73%) had normal exercise-ECG. On the basis of the scintigraphies before PTCA, the patients were divided into two groups: In group 1, five had normal scintigraphy and 14 reversible perfusion defects only. In group 2, all 11 patients had both persistent and reversible defects. In patients without persistent defects, significantly more were free from angina. No difference was observed between group 1 and 2 in percentage stenosis of the vessel or in reduction of the diameter. Significant reduction in the extent of reversible perfusion defects after PTCA was observed in both groups and also in the extent of persistent defects in group 2. In about 1/3 of the patients, the changes in percentage stenosis after PTCA and in the perfusion as judged by the scintigraphies differed. Therefore, as the two methods supplement each other, the main conclusions are: 1) Evaluation of the revascularization procedure is more reliable if a scintigraphy is obtained both before and after PTCA than if only coronary arteriography is performed. 2) Scintigraphy alone suffices for the three-month follow-up examination, partly because it gives better information about the myocardial perfusion than does the arteriography, partly because scintigraphy is a noninvasive procedure.
