Coronary angioplasty using new 6 french guiding catheters

Abstract
Coronary angioplasty (PTCA) was performed with specially constructed 6‐French guiding catheters with an internal lumen of 0.051 inches. In 154 patients these guiding catheters were used in a variety of configurations in conjunction with miniature balloon‐on‐a‐wire dilatation catheters in 1.5 to 3.5 mm sizes to perform PTCA. Overall patient success was 94%. PTCA was attempted in 24 totally occluded arteries with a success rate of 83% and 174 stenoses with a success rate of 97%. 6 French guiding catheters can be used to successfully perform PTCA.
