Percutaneous Transluminal Coronary Angioplasty for Multiple Lesions in a Coronary Artery-Report of Two Cases : REPORT OF A SATELITE SYMPOSIUM OF THE JAPANESE CIRCULATION SOCIETY ON THE INITIAL JAPANESE EXPERIENCE OF PERCUTANEOUS TRANSLUMINAL CORONARY ANGIOPLASTY

Abstract

Percutaneous transluminal coronary angioplasty (PTCA) was performed successfully in two patients with angina pectoris who had two separate significant stenotic lesions in a coronary artery. One patient had stenoses in segments 6 and 7 of the left anterior descending coronary artery. After PTCA, angina disappeared, an exercise ECG became negative and a ²⁰¹Tl myocardial scintigram returned to normal. In the other patient, two separate stenotic lesions were found in segment 3 of the RCA. Angina and an exercise ECG improved after PTCA. These results suggests the validity of PTCA for multiple stenotic lesions in the same coronary artery.
