Left Distal Radial Artery Access for Coronary Angiography and Interventions: A 12-Month All-Comers Study.

J Invasive Cardiol 2022 Jul 17;34(7):E505-E509. Epub 2022 Jun 17.

General Hospital Papageorgiou, Ring Road of Thessaloniki, Nea Efkarpia, Thessaloniki, 56403, Greece.

Background: Interventional cardiologists prefer the right radial artery (RA) approach for coronary angiography and interventions, mainly for ergonomic reasons. However, the use of the left RA presents certain advantages, and the snuffbox approach has further potential advantages, including lower probability for RA occlusion, avoidance of direct puncture of the RA (thus maintaining its suitability for use as a graft), as well as easier and faster hemostasis.

Methods: Consecutive patients scheduled for coronary catheterization were included, using the left distal RA (ldRA) in the anatomical snuffbox as the default vascular access site. Read More

10 best practice tips with radial arterial catheterization.

J Vasc Access 2022 Jun 2:11297298221101243. Epub 2022 Jun 2.

Clinical & Medical Affairs, Teleflex Incorporated, Morrisville, NC, USA.

Radial arterial catheters (RAC) are used extensively across critical care settings (Anesthesia, Intensive Care, Emergency Medicine) for continuous hemodynamic monitoring, allowing for immediate adjustments in vasopressor therapies and blood collection. Radial catheter failures are an ongoing significant issue for critical care clinicians with reported incidences at almost 25%. Common complications include loss of function, lack of blood return, poor quality waveforms and dislodgement, posing potential patient risks, and sudden loss of intra-arterial monitoring frequently requires prompt replacement.

Simplified TAVR Procedure: How Far Is It Possible to Go?

J Clin Med 2022 May 16;11(10). Epub 2022 May 16.

Department of Cardiology, Montpellier University Hospital, 34295 Montpellier, France.

Increasing operators' experience and improvement of the technique have resulted in a drastic reduction in complications following transcatheter aortic valve replacement (TAVR) in patients with lower surgical risk. In parallel, the procedure was considerably simplified, with a routine default approach including local anesthesia in the catheterization laboratory, percutaneous femoral approach, radial artery as the secondary access, prosthesis implantation without predilatation, left ventricle wire pacing and early discharge. Thus, the "simplified" TAVR adopted in most centers nowadays is a real revolution of the technique. Read More

Feasibility of nitroglycerin patch as a pretreatment for the distal radial approach: Study protocol for a randomized controlled trial (DRANG study).

Cardiovasc Revasc Med 2022 May 13. Epub 2022 May 13.

Department of Cardiovascular Medicine, National Cerebral & Cardiovascular Center, 6-1, Kishibe-shimmachi, Suita, Osaka 564-8565, Japan; Department of Advanced Cardiovascular Medicine, Graduate School of Medical Sciences, Kumamoto University, 1-1-1, Honjo, Chuo-ku, Kumamoto 860-8556, Japan.

Background: The distal radial approach (DRA) is a novel catheter cannulation technique to access the distal radial artery for coronary angiography (CAG). It is associated with less occurrence of puncture site occlusion than the conventional transradial approach. However, cannulation failure occasionally occurs due to difficulty in puncturing the smaller distal radial artery. Read More

Distal Versus Conventional Radial Access for Coronary Angiography and Intervention: The DISCO RADIAL Trial.

JACC Cardiovasc Interv 2022 Jun 17;15(12):1191-1201. Epub 2022 May 17.

Department of Cardiology, Shonan Kamakura General Hospital, Kanagawa, Japan.

Background: Currently, transradial access (TRA) is the recommended access for coronary procedures because of increased safety, with radial artery occlusion (RAO) being its most frequent complication, which will increasingly affect patients undergoing multiple procedures during their lifetimes. Recently, distal radial access (DRA) has emerged as a promising alternative access to minimize RAO risk. A large-scale, international, randomized trial comparing RAO with TRA and DRA is lacking.

Distal transradial access for targeted spinal angiography and embolization.

Interv Neuroradiol 2022 Apr 28:15910199221097489. Epub 2022 Apr 28.

Department of Clinical Neurosciences, 26634Foothills Medical Centre, Calgary, Alberta, Canada.

Background: Spinal catheter angiography is commonly performed in the evaluation and treatment of spinal vascular lesions. The typical approach to spinal angiography consists of access through the femoral artery with the use of suitably shaped catheters for selective catheterization of the spinal segmental vasculature. The purpose of our study was to evaluate the safety and feasibility of distal transradial access through the "anatomical snuffbox" for targeted spinal angiography, for the investigation and treatment of selected spinal lesions.
