Rates of the Trans-radial Approach in Elective and Emergency Coronary Angiography in Iraq: A Cross-Sectional Study.

Background and aims The trans-radial access is becoming the default approach in many cardiac centers worldwide. Data from the Middle East, including Iraq, on the trends and rates of the use of trans-radial access are scarce. The aim of this study is to determine the rates of trans-radial approach (TRA) versus transfemoral approach (TFA) in patients with coronary artery syndromes undergoing coronary angiography and/or percutaneous coronary intervention (PCI) in Iraq. Methods In this multicenter prospective study, we collected 885 cases of coronary artery disease undergoing coronary angiography/PCI from three main cities of the Kurdistan Region in Iraq from 2022 to 2023. Results Of the total sample, 57.2% were diagnostic coronary angiography and 42.8% were PCI, 57.1% of all cases were TFA and 42.9% were TRA, and 64.3% of PCI cases were performed through TFA. Eghty-two percent of total emergency PCI included (primary PCI) cases underwent the procedure through the TFA, and only 18% of such cases were through the TRA. The overall crossover rate between both approaches happened in 14 (3.6%) cases. Conclusions Despite its main benefits, the radial access use in the Cath lab is yet underused in our region. Further steps in training programs are indicated to popularize the use of radial access among interventional cardiologists in addition to transfemoral access.
