Transradial Intervention

Transradial Intervention

A catheter is inserted via the radial artery in the wrist to deliver stents to narrowed or blocked blood vessels such as coronary arteries. Conversely, catheters may be introduced through an artery in the upper leg which was once the standard for this type of treatment. However continued development of balloon catheters and stents, has enabled access through the smaller vessels in the wrist.

Patients with unknown bypass graft anatomy, upper-extremity hemodialysis accesses, small radial arteries, abnormal Allen or oximetry tests, large transfemoral devices or hemodynamic support are not favorable candidates for this approach.

Transradial intervention today, is preferred to transfemoral, as it is less invasive. The smaller diameter of wrist arteries means smaller incisions are required, and patients can walk immediately after the procedure has been completed, contributing to quicker recovery. It also reduces the possibility of internal bleeding and other complications. Additionally, shorter hospitalisation time implies a reduced economic burden on the patient.

Intracoronary Physiology FFR:

In an ischemic heart, Fractional flow reserve (FFR) is a parameter derived from measuring coronary pressures that helps clinical decision-making for revascularization (restoration of circulation). The FFR helps the cardiac team estimate the degree to what the coronary blood flow has been impaired.

Especially in patients with multi-vessel disease, FFR guides the decision about whether to revascularize and helps reclassify the number of vessels that are diseased.
