Outpatient coronary arteriography

A total of 12,719 outpatient coronary angiograms have been performed, using the Sones Technique, at Butterworth Hospital in Grand Rapids, Michigan, over the past 14 years. A consecutive series of 5,107 of these outpatient angiograms were selected for review here. Sixty‐one percent of these patients were diagnosed with coronary artery disease.
