BACKGROUND The rate of cardiovascular implantable electronic device infections (CIEDIs) has mirrored or exceeded the increased use of implantable cardiac devices in the United States. The presence of racial and ethnic disparities associated with CIEDIs has not been published. Our aim is to describe the presence of racial and ethnic disparities with respect to the management of CIEDIs. METHODS We reviewed a prospective single-center registry for patients undergoing removal of an implantable cardiac device between 1/2004 and 1/2016. 1173 consecutive patients underwent device extraction. 699 patients were identified as having an infection, 305 were identified as Caucasian and 394 were minorities (91 African Americans, 303 Hispanics). Patients had pre-operative transesophageal echocardiograms (TEEs) and collection of blood and exudate cultures. All underwent complete hardware extraction; leads were removed through the use of locking stylets and traction or laser extraction. En-bloc capsulectomy was performed with intraoperative specimen collection from pocket tissue, exudate, lead tips, and vegetations. RESULTS Minority patients were: younger (67.9 ± 14.5 years vs 72.4 ± 13.2 years), had a higher proportion of male gender, diabetes, and chronic renal failure (p < 0.001). Minorities experienced a higher rate of complications during extraction and a longer hospitalization (15.3 ± 9.9 days versus 17.4 ± 13.4 days, p < 0.001). There was no significant difference between the proportion of types of infection in both groups. CONCLUSION Minority patients with CIEDIs experienced more procedural complications during extraction and had a significantly longer length of index hospitalization than Caucasian patients.
