Radial versus femoral access for rotational atherectomy angioplasty

Abstract

Abstract Introduction The transfemoral approach (TFA) is a potentially advantageous acess site for complicated and prolonged percutaneous coronary angioplasty like rotational atherectomy (RA). Despite this, there is mounting data that suggests the transradial approach (TRA), an alternative to the TFA acess, is linked to reduced rates of mortality and access site complications. Aim This study was conducted with the aim of providing a quantitative appraisal of clinical outcomes of TRA for patients undergoing RA procedure. Methods In this retrospective study, we analyzed all RA procedures performed from March 2013 to June 2019 at our single center institution. Primary endpoints were procedural success, in-hospital mortality, and major adverse cardiovascular events (MACE) during hospitalization. Results Of the 98 patients undergoing RA, the TRA approach was chosen for 79% patients, and the TFA approach for 21% patients. No significant difference in procedural success rates was observed (94% vs. 91%, p=0.19). The use of RA via TRA correlated with a lower contrast volume (p=0.027) and a decreased post-procedure hospital stay (p=0.005). After multivariate adjustment, TRA demonstrated a noteworthy reduction in in-hospital mortality odds (OR: 0.62; 95% CI: 0.44 to 0.87; p = 0.003), major bleeding (OR: 0.48; 95% CI: 0.33 to 0.70; p < 0.001), MACE (OR: 0.68; 95% CI: 0.51 to 0.89; p = 0.015), and 30-day mortality (OR: 0.68; 95% CI: 0.51 to 0.89; p = 0.015). Conclusions Even though RA is a complex procedure, employing radial access (TRA) might be associated with favorable outcomes. These include a lower contrast volume, shorter hospital stay, and reduced odds of in-hospital mortality, major bleeding, MACE, and 30-day mortality compared to femoral access (TFA).
