Conditions

Coronary Angiography, Distal Radial Artery Access (dTRA), Radial Artery Intimal Medial Thickness, Transradial Access

Brief summary

Prospective randomized non-blinded study to determine degree of vessel trauma and adverse remodeling of the proximal forearm radial artery following distal radial artery access (dTRA) for cardiac catheterization compared to standard forearm transradial access (fTRA).

Detailed description

To determine degree of vessel trauma and adverse remodeling of the proximal forearm radial artery, using ultrahigh resolution (55 MHz) ultrasound, following distal radial artery access (dTRA) for cardiac catheterization compared to standard forearm transradial access (fTRA) at 90 days post-procedure. Secondary outcome measures will include metrics of procedural success at 24 hours, as well as functional assessment of pain and motor strength of the ipsilateral upper extremity at 90 days post-procedure.

Interventions

PROCEDUREdTRA

Subjects randomized to the experimental arm will undergo left heart catheterization, coronary angiography and/or percutaneous coronary intervention using distal transradial access (dTRA)

PROCEDUREfTRA

Left heart catheterization, coronary angiography and/or percutaneous coronary intervention using the left forearm radial artery.

Intervention model description

Prospective randomized non-blinded study evaluating whether distal radial artery access (dTRA) from the anatomic snuffbox is associated with less trauma and adverse remodeling to the forearm radial artery compared to standardard forearm radial access (fTRA).

Inclusion criteria

1. Consecutive patients undergoing elective and non-emergent TR LHC and/or PCI at the INOVA Heart and Vascular Institute 2. Able to provide informed consent. 3. Patients willing to complete a 90day post PCI radial artery ultrasound.

Exclusion criteria
