Distal Versus Proximal Radial Artery Access for Cardiac Catheterization: 30-Day Outcomes of the DIPRA Study.

Background Proximal radial artery (pRA) access for cardiac catheterization is safe but can jeopardize subsequent use of the artery because of occlusion. Distal radial artery (dRA) access in the anatomical snuffbox preserves the radial artery, but safety and potential detrimental effects on hand function are unknown. Methods and Results In the DIPRA (Distal Versus Proximal Radial Artery Access for Cardiac Catheterization and Intervention) study, a single-center trial, 300 patients were randomized 1:1 to cardiac catheterization through dRA or pRA.

Screening for SARS-CoV-2 via PCR and serological testing in asymptomatic healthcare workers.

The prevalence and seroconversion rate of SARS-CoV-2 infection among asymptomatic health care workers in the US is unclear. Our study utilized real-time polymerase chain reaction (RT-PCR) SARS-CoV-2 testing and serological evaluation to detect IgG antibodies specific to SARS-CoV-2 antigens in asymptomatic health care workers. A total of 197 subjects with a mean age of 35 years were recruited into the study.

Distal Versus Proximal Radial Artery Access for Cardiac Catheterization and Intervention: Design and Rationale of the DIPRA Trial.

Background: Radial artery (RA) catheterization is the access of choice over femoral artery access for most interventional vascular procedures given its safety and faster patient recovery. There has been growing interest in distal radial artery (dRA) access as an alternative to the conventional proximal radial artery (pRA) access. Preserving the RA is important which serves as a potential conduit for future coronary artery bypass surgery, dialysis conduit or preserve the artery for future cardiovascular procedures.
