Objective Driveline infection is a common complication of durable left ventricular assist device support. The majority involve the driveline exit site and can be treated with antibiotics and local wound care. Less frequently, these infections extend into deeper tissues and surgical debridement is necessary. Few studies have described the surgical strategy for treatment of deep driveline infection or have reported long-term outcomes. With a growing population of patients being implanted as destination therapy, there is an obvious need to evaluate and optimize treatment for complex driveline infections. Methods Outcomes of patients undergoing durable left ventricular assist device implantation at a single center between 2011 and 2017 were reviewed retrospectively. Data including occurrence of driveline infection, pathogen, time to driveline infection, and treatment strategy were abstracted from the electronic medical record. Results Driveline infection occurred in 10 (16.4%) of 61 patients at a median of 362 days (Q1 = 99, Q3 = 694) after primary left ventricular assist device implantation. Three (30.0%) of 10 driveline infections were categorized as deep and did not resolve with intravenous antibiotic therapy. In these cases, a multistage approach that included initial debridement and exteriorization of the infected driveline, followed by delayed surgical relocation of the driveline in a clean vascularized soft tissue bed, was used. Long-term device salvage was achieved in all cases. Conclusions An aggressive surgical strategy, including debridement and formal relocation of the driveline exit site, can result in long-term device salvage after deep driveline infection. This approach is a less invasive alternative to device exchange for refractory driveline infections.

Left ventricular assist systems are being developed for eventual long term or permanent implantation as an alternative to heart transplantation in patients unsuitable for or denied the transplant option. Evaluation of the effects of these devices upon normal physiology is required. A preliminary study was conducted to evaluate the morphology of aortic tissue from calves implanted with a pneumatic Left Ventricular Assist device-LVAD. Two 3 month old heifer calves (calf 1 and calf 2) were electively explanted after 128 days and 47 days respectively. Descending thoracic aortic tissue from both animals was removed immediately post mortem and placed into karnovsky’s fixative. The tissue was subsequently processed for transmission electron microscopy (TEM). Some aortic tissue was fixed in neutral buffered formalin and processed for routine light microscopy.
