RESUMO
BACKGROUND: Ventricular assist devices driveline infections are common, recalcitrant, and carry high morbidity and mortality. Herein, we reported a patient with driveline infection that was successfully treated with a combination of systemic antibiotics, surgical debridement, and instillation of absorbable antibiotic beads to the wound bed. METHODS AND RESULTS: A 39-year-old man with nonischemic cardiomyopathy underwent insertion of a continuous flow left ventricular assist device. Four years postoperatively, the patient presented with clinical, laboratory, and radiologic signs of driveline tract infection. He underwent extensive surgical debridement, installation of absorbable antibiotic beads that consisted of calcium sulfate, vancomycin, and tobramycin, into the wound bed, and systemic antibiotics. The patient was free of infection 9 month postoperatively. CONCLUSION: Absorbable calcium sulfate antibiotic beads may serve as a beneficial adjunct to surgical debridement and systemic antibiotics for the treatment of ventricular assist device driveline infection, and merit further investigation.

Cardioplegic arrest of the severely compromised ventricle may make weaning from cardiopulmonary bypass problematic. We report a novel approach to myocardial protection in a patient requiring multi-valve surgery who had an ejection fraction of 15%. Warm oxygenated blood was infused continuously both antegrade and retrograde during aortic valve replacement and mitral and tricuspid valve repair. Adequacy of perfusion was confirmed by the absence of electrocardiographic changes. Clinical improvement suggests that this strategy of myocardial protection warrants further investigation.
