Abstract
Objectives
We retrospectively assessed the initial clinical impact of the locally administered bacteriostatic antibiotic, powder minocycline, during surgery for active infective endocarditis (AIE).
Methods
Among 38 surgical AIE patients, 36 patients who underwent surgical intervention for AIE using local administration of powder minocycline between January 2008 and August 2017 in our institute were enrolled. During surgery, the local administration and dispersion of powder minocycline at not only the valvular annulus and perivalvular cavity, but also the prosthetic cuff and ring were performed following the complete resection and aggressive debridement of infectious tissues. Early clinical outcomes, including survival, postoperative co-morbidities, and freedom from re-intervention or significant paravalvular leakage (PVL), were assessed.
Results
Early mortality within 30 days was 5.6% and hospital death was 13.9%. There was no reoperation within 30 days and only one patient (3.8%) developed recurrent infection, which improved with additional antibiotic treatments. More than moderate PVL within 30 days was detected in one patient only (3.8%). Over a median follow-up period of 38.3 ± 35.5 months, a Kaplan–Meier analysis revealed that 1- and 5-year survival rates were 75.7 and 66.8%, respectively, and freedom from reoperation was 100% at 5 years. Freedom from significant PVL at 5 years was 91.0%.
Conclusions
The local administration of powder minocycline may be a simple and effective manipulation during surgical intervention for AIE without extensive reconstruction; however, the surgical management of AIE remains challenging.
