title: Progression of coronary disease in candidates for transluminal coronary angioplasty.
abstract: Five of our first 20 candidates for PTCA had unanticipated occlusion of the relevant coronary artery between the time of coronary angiography and PTCA. None had a change in symptoms or ECG to suggest coronary occlusion. We currently schedule PTCA within a month to help avoid this occurrence.
