Late coronary stent infection: a unique complication after drug-eluting stent implantation.

A 75-year-old male developed late coronary stent infection with symptoms presenting months after the initial procedure. This presentation was notably different than that of other cases in the literature, which typically presented days to a few weeks after stent implantation. Persistently unendothelialized stent struts may be a nidus for late infection.

Nonocclusive radial artery injury resulting from transradial coronary interventions: radial artery IVUS.

Objective: The purpose of the present study was to evaluate nonocclusive radial artery injury resulting from transradial access.

Background: The benefits of transradial access for coronary intervention have been well documented, but resulting intima-media hyperplasia could be a limitation.

Methods: Thirty patients undergoing transradial coronary intervention (Group A: 15 de novo procedures, Group B: 15 previous transradial procedures) underwent radial artery intravascular ultrasound (IVUS) before catheter insertion.
