title: Safety and efficacy of AVE gfx stent implantation via 6 Fr guiding catheters.
abstract: This prospective study was designed to determine the feasibility of AVE gfx premounted stent systems in combination with 6 Fr guides. Between 1 April and 12 August 1997, 230 patients underwent AVE gfx coronary stent implantation via 6 Fr guides. The radial approach was used in 146 patients (63.5%). In 230 procedures (293 lesions), 237 guiding catheters were used. A total of 331 AVE gfx stents were implanted, 1.4 per patient. Backup, opacification, and friction were considered good in 85.8%, 96.4%, and 76.7%, respectively. Slight and severe friction was felt during combined use of long (> or = 18 mm), large-sized (3.5 mm) stents and small-sized guiding catheters (inner diameter, 0.061-0.062"). The presence of a second protecting guidewire impaired passage of the AVE gfx stent, also in large 6 Fr guides (ID 0.064"). Of 331, 320 (96.7%) stents were successfully deployed at the initial attempt. Ten stents (3%) had to be retrieved. Six of these were successfully placed at a second attempt and three slipped off the balloon, all successfully retrieved from the patient's circulation. At 1 month, 217 patients (94.4%) were free of events. The AVE gfx stent is compatible with 6 Fr guiding catheters. Use of new-generation, large-bore 6 Fr gc (> or = 0.064") is recommended.
