Abstract Body (Do not enter title and authors here): Introduction: Candidemia is rare but associated, have significant morbidity and mortality. Outcomes are not well-characterized in patients with left ventricular assist devices (LVADs). With an increasing number of patients living with LVADs, we sought to characterize risk factors to help optimize outcomes for this high-risk population.

Methods: We retrospectively reviewed records of 97 patients who underwent LVAD implant between January 2012 to May 2024 at Indiana University Health, Indianapolis Indiana. Demographic and clinical data were extracted. Candidemia was defined as a positive blood culture with candida species.

Result: We identified three patients with candidemia, with an overall attack rate of 3.09%. All patients had a HeartMate III (HM3) at the time of infection. The mean age of patients was 40.3 years (Range 29.0 – 58.0 years) and mean BMI was 35.7 kg/m² (Range, 30.0 – 42.0 kg/m²). One patient grew Candida auris and Candida tropicana, the other patient grew Candida auris and the third patient grew Candida globrata. All patients had an automatic implantable cardiac defibrillation, a peripherally inserted central catheter line, and right heart failure. Two patients had driveline infections (one fungal, one bacterial) while one patient developed LVAD endocarditis with a right ventricular outflow tract vegetation. Two patients had persistently positive blood cultures despite treatment with a multi-drug anti-fungal regimen (Flucytosine, Amphotericin B and micafungin) and expired. The third patient initially cleared her blood cultures after treatment with IV micafungin only but was re-admitted with muti-organ failure and expired. Summarily, all patients with candidemia died with a mortality rate of 100%. None of the patients were candidates for heart transplantation. Average survival from the time of diagnosis of candidemia was 5 months (Range 1.0 – 11.0 months). RHF, chronic DL infection and high BMI were associated with candidemia in our series.


Conclusion: Candidemia in LVAD patients, while less common than bacterial infections, carry high mortality without cardiac transplantation (100% mortality in our cohort). Its rare occurrence makes it challenging to identify reversible risk factors, leading to poor survival. Multicenter registries are needed to fully elucidate these risk factors and determine effective treatment strategies.
