Filter by:Non-inferiority, prospective, multi-center, post-market, randomized 1:1 study in patients with uncontrolled hypertension to compare the safety and efficacy of radio frequency renal denervation using Iberis Renal Denervation System via radial access compared with femoral access.
Several approaches have been proposed to reduce the risk of RAO, including anticoagulation, immediate postprocedural sheath removal, and a small sheath/radial artery ratio. Doppler ultrasound examination showed that interrupted blood flow in RA tend to occur in the proximal end rather than distal part of the artery,which was ignored by a majority of interventional cardiologists. Different insights into occlusion location may lead to different options of sheath materials, models, catheters and puncture access. Thus, the investigators designed this present study to explore the reason of radial artery endothelial dysfuction and damage and occlusion location by flow-mediated dilation (FMD) to determine the suitable method to reduce occlusion risk during TRI.
The transradial approach for coronary angiography and angioplasty is now widely used in catheterization laboratories worldwide, which had been shown as advantages over the conventional femoral and brachial approaches due to the lower incidence of bleeding and other cardiovascular complications. However, the transradial approach does not seem suitable for 5-15% of patients undergoing coronary angiography and angioplasty. The ulnar artery which is one of the two terminal branches of the brachial artery is usually larger than radial artery and it may be as a potential approach for cardiac catheterization. Recently, some reports have demonstrated that the transulnar approach may be both feasible and safe for coronary angiography and angioplasty in selective patients.we performed this study to evaluate the safety and feasibility of transulnar approach coronary catheterization in real world non-selective patients.
