International Hand Function Study Following Distal Radial Access: The RATATOUILLE Study.

Background: Distal radial access (DRA) has been proposed to improve procedure ergonomics and favor radial artery patency. Although promising data, nothing is known on evolving hand function after DRA.

Objectives: This study sought to comprehensively evaluate hand function in patients undergoing DRA.

Distal Versus Conventional Transradial Artery Access for Coronary Angiography and Intervention: A Meta-Analysis.

Background: Distal transradial artery access (dTRA) through the anatomical snuffbox is a novel approach for performing coronary angiography and interventions. However, the safety and efficacy of dTRA as compared to conventional TRA (cTRA) remains unknown. We aim to evaluate the outcomes of dTRA versus cTRA for coronary angiography and intervention.

Distal arteriovenous fistula formation after percutaneous coronary intervention: An old complication of a new access site.

Dorsal or distal transradial artery access has recently gained popularity due to several perceived benefits that include favorable ergonomics, the potential for rapid hemostasis and lower rates of vascular complications. Still, no vascular access site is free of complications and reports of hematoma and pseudoaneurysm formation related to distal radial artery access have been reported in the literature. We present a case of a 71-year-old male who developed an arteriovenous fistula (AVF) involving the distal left radial artery following repeated access of the artery.

Validation of the all-comers design: Results of the TARGET-AC substudy.

Background: Results of clinical trials are often criticized by low inclusion rate and potential sampling bias in patient recruitment. The aim of this validation registry is to evaluate how far an all-comers design in the context of clinical research can ensure the representation of the true all-comers population.

Methods: This validation registry is a prospective international multicentre registry, conducted at 10 out of the total 21 centers, participating in TARGET-AC (registered under NCT02520180).
