Abstract
Although the transradial approach is well established for percutaneous coronary intervention (PCI), it is perceived as being not suitable for 7-Fr complex PCI, which is traditionally performed from the femoral approach. To evaluate the procedural success and outcome of 7-Fr transradial complex PCI. Retrospective review and analysis of all patients undergoing 7-Fr transradial complex PCI from August 2008 until October 2010 in a tertiary cardiac center setting. Transradial 7-Fr complex PCI was performed in 77 patients after manual assessment of the radial pulse and size. The radial access was obtained successfully in all 77 patients. The age range was 39-88 years with 16 patients (23.4%) over 80 years of age and 14 females (18.1%). There were 30 left main stem PCI (39%), 31 (40.2%) chronic total occlusion (CTO), and 13 (16.8%) rotational atherectomy. Intravascular ultrasound (IVUS) was used in 17 (22%) cases, cutting balloons in 16 (20.7%), and LASER PCI in 2 (2.6%) cases. Procedural success was achieved in 76 of 77 (98.7%) with 1 failure to canalize a CTO. There was 1 patient with type I coronary perforation managed conservatively. There was no in-hospital mortality. All radial pulses were present 6 hours after the procedure and only 23 patients were seen for follow-up, and all had patent radial artery 4-6 months following the procedure. A 7-Fr transradial complex PCI is feasible and can be carried out safely and successfully with excellent results. In suitable patients, male or female, complex PCI need not always be performed from the femoral approach.
