Intraoperative balloon-catheter dilatation in the treatment of coronary artery disease.
Intraoperative balloon angioplasty has been employed as an adjunct to conventional coronary artery bypass techniques for arteriosclerotic obstructions in areas difficult to expose. In 14 patients having repeat cardiac catheterization prior to discharge from the hospital, an average preoperative stenosis of 50% was reduced to 26% in 14 arteries subjected to angioplasty. In four patients, improvement was less than 20%. There were no known complications, and time to perform the procedure was less than 10 minutes per angioplasty. Intraoperative angioplasty is indicated when normal sequential or multiple grafting procedures cannot be performed, but the procedure may have a significantly higher long-term failure rate than coronary artery bypass alone.
