Abstract
BACKGROUND: Left ventricular assist devices (LVADs) have become useful adjuncts in the treatment of patients with end-stage heart failure. LVAD implantation is associated with a unique set of problems; one such problem is device infection. We report our experience with flap salvage of infected and/or exposed LVAD hardware. METHODS: Between 2011 and 2016, 49 patients underwent LVAD implantation at our institution. Patients were then categorized by infectious status: systemic infection not directly involving the LVAD device, hardware infection responsive to antibiotics, and exposure of LVAD hardware or device infection refractory to antibiotics requiring debridement and flap coverage. RESULTS: Approximately 50% of device-related infections resolved with either oral or intravenous antibiotics while the other 50% necessitated debridement and coverage with healthy tissue. In total, 12 patients (24%) developed a device-related infection ranging from superficial driveline cellulitis to purulent pocket infections. Seven patients (14%) required extensive debridement and/or flap coverage. CONCLUSION: Early debridement and coverage of exposed hardware are crucial to successfully treating these LVAD infections.
