Background: Palpation-guided access of the radial artery (RA) has transradial access (TRA) failure rates averaging 6%-7%. This study aimed to measure RA and ulnar artery (UA) diameters by ultrasound in a typical American population, in hopes of elucidating data that may improve TRA success rates.
Methods: Intraprocedural ultrasound measurements of the RA and UA in 565 consecutive patients undergoing TRA were retrospectively analyzed.
Objective: Arterial access from the wrist for cardiac catheterization is increasingly being used. Right heart catheterization (RHC) is an integral part of many of these procedures. Reliable venous access from the arm allows avoidance of femoral or jugular venous access for RHC.

This study investigated if use of a chitosan-based hemostatic pad (Clo-Sur Radial™) combined with mechanical compression (TR Band®) could shorten hemostasis time after TRA, compared with a TR Band® alone.
Methods: 40 patients undergoing cardiac catheterization and/or percutaneous coronary intervention were assigned into 4 cohorts post TRA: 10 patients received mechanical compression with a TR Band® alone for 120 min.

With the increased use of transradial artery access (TRA) for diagnostic and coronary interventional procedures, crossover to the ipsilateral ulnar artery after TRA failure is being reported more frequently. A major challenge with ipsilateral transradial and ulnar artery access is achieving efficient patent hemostasis of both the radial and ulnar arteries at the completion of the procedure. In this report, we describe two cases of failed TRA with subsequent ipsilateral ulnar artery access.

Methods: Thirty patients undergoing TRA coronary angiography and/or percutaneous coronary intervention were randomized into three cohorts post TRA: 10 patients received mechanical compression with the TR Band, 10 patients received 30 min of compression with the QuikClot Radial pad, and 10 patients received 60 min of compression with the QuikClot Radial pad.
Objectives: Ultrasound evaluation of both the radial artery (RA) and ulnar artery (UA) in patients undergoing cardiac catheterization/percutaneous coronary intervention.
Background: Arterial access from the wrist is almost exclusively obtained from the RA. Crossover to secondary femoral arterial access was observed in up to 7.
Objectives: To evaluate several techniques to reduce crossover rates in wrist artery access in patients undergoing cardiac catheterization (CC)/percutaneous coronary intervention (PCI).
Background: Palpation-guided radial artery (RA) access for CC/PCI is associated with a crossover rate to femoral artery (FA) access in up to 7.6%.
Aims: The aim of this study was to test the radioprotection efficacy and comfort of newer bilayer barium sulphate-bismuth oxide composite (XPF) caps in an interventional cardiology setting.
Methods And Results: Operators were randomly assigned to wear standard fabric (n=59), 0.3 mm (n=74), or 0.
Objectives: This study sought to assess the utility of ultrasound (US) guidance for transradial arterial access.
Background: US guidance has been demonstrated to facilitate vascular access, but has not been tested in a multicenter randomized fashion for transradial cardiac catheterization.
Methods: We conducted a prospective multicenter randomized controlled trial of 698 patients undergoing transradial cardiac catheterization.
