Management of a chronically infected left ventricular assist device with heart transplantation: Two-step simplified approach.

BACKGROUND: The surgical approach for the treatment of a left ventricular assist device with severe infection may be controversial. MATERIAL & METHODS: We present the case of a patient implanted with a HeartWare™ HVAD as a bridge to transplant and chronic infection of the device by Pseudomonas who underwent a conservative partial treatment of the driveline tunnel and subsequently a heart transplantation and device removal were done. CONCLUSIONS: The two-step simplified approach allowed the patient to be transplanted in a short period of time, with the abdominal wall healed and almost two-thirds of the driveline subcutaneous tunnel sterilized.

Characteristics of patients with survival longer than 20 years following heart transplantation.

INTRODUCTION AND OBJECTIVES: The number of heart-transplant recipients exceeding 20 years of follow-up is steadily increasing. However, little is known about their functional status, comorbidities, and mortality. Identifying the predictors of prolonged survival could guide the selection of candidates for the low number of available donors. METHODS: Functional status, morbidities, and mortality of heart-transplant patients between 1984 and 1992 were analyzed. To identify predictors of 20-year survival, a logistic regression model was constructed using the covariates associated with survival in the univariate analysis. RESULTS: A total of 39 patients who survived 20 years (26% of patients transplanted before 1992) were compared to 90 recipients from the same period who died between 1 and 20 years post-transplantation. Major complications were hypertension, renal dysfunction, infections, and cancer. After a mean follow-up of 30 months, 6 survivors had died, yielding a mortality rate of 6% per year (vs 2.5%-3% in years 1-19). Causes of mortality were infection (50%), malignancy (33%), and allograft vasculopathy (17%). Long-term survivors were younger and leaner, and had nonischemic cardiomyopathy and lower ischemic time. Logistic regression identified recipient age <45 years (odds ratio=3.9; 95% confidence interval, 1.6-9.7; P=.002) and idiopathic cardiomyopathy (odds ratio=3; 95% confidence interval, 1.4-7.8; P=.012) as independent predictors for 20-year survival. CONCLUSIONS: One fourth of all heart-transplant patients in our series survived >20 years with the same graft, and most enjoy independent lives despite significant comorbidities. Recipient age <45 years and idiopathic cardiomyopathy were associated with survival beyond 2 decades. These data may help decide donor allocation.
