Prevention of Cardiac Implantable Electronic Device-Related Infection in Patients With Cancer: The Role of a Comprehensive Prophylactic Bundle Approach That Includes the Antimicrobial Mesh.

BACKGROUND

Oncological patients have several additional risk factors for developing a cardiac implantable electronic device (CIED)-related infection. Therefore, we evaluated the clinical impact of our comprehensive bundle approach that includes the novel minocycline and rifampin antimicrobial mesh (TYRX) for the prevention of CIED infections in patients living with cancer.

METHODS

We retrospectively reviewed all consecutive patients who had a CIED placement at our institution during 2012-2017 who received preoperative vancomycin, intraoperative pocket irrigation with bacitracin and polymyxin B, plus TYRX antimicrobial mesh, followed by postoperative oral minocycline.

RESULTS

A total of 154 patients had a CIED, with 97 permanent pacemakers (PPMs), 23 implantable cardioverter defibrillators (ICDs), and 34 cardiac resynchronization therapy (CRT) devices. An underlying solid cancer was present in 62% of patients, while 38% had a hematologic malignancy. Apart from a higher proportion of surgical interventions in the PPM group than in the ICD and CRT groups (P = .007), no other oncologic variables were statistically significantly different between groups. Despite an extensive median follow-up period (interquartile range) of 21.9 (6.7-33.8) months, 16 patients (10%) had a mechanical complication, while only 2 patients (1.3%) developed a CIED infection, requiring the device to be explanted.

CONCLUSIONS

Our comprehensive prophylactic bundle approach using TYRX antimicrobial mesh in an oncologic population at high risk for infections was revealed upon extensive follow-up to be both safe and effective in maintaining the rate of CIED infection at 1.3%, well within published averages in the broader population of CIED recipients.
