Abstract

This is a “proof of concept” study to assess feasibility of transradial access without use of vasodilators. Radial artery spasm (RAS) is an important cause of patient discomfort and procedural failure with use of radial access. Vasodilators are routinely used to prevent RAS. However, the use of vasodilators may not be appropriate in substantial groups of patients. These include patients with myocardial infarction and low blood pressure who will benefit from radial access the most. No specific recommendations about use of vasodilators in these settings are stated on consensus documents on radial access. During a short period of shortage of verapamil in our country, 15 consecutive patients underwent cardiac catheterization by transradial route without the use of vasodilators. Procedural success, and pain perceived by the patients along with radial occlusion after the procedure were assessed. In 14 of the 15 patients, the procedure was completed successfully without the use of vasodilators. In one patient, RAS developed and the procedure could be completed after injection of verapamil. Mean pain score was 5.3 on a scale of 0 to 10. No radial occlusion was detected early after the procedure. In three of the patients, a reason that would otherwise preclude use of a vasodilator was identified. Radial access can safely and effectively be performed without the use of vasodilators. Consideration of this approach when use of vasodilators is not appropriate should be formally discussed by the interventional cardiology community.
