Background: In this study, we aimed to investigate frequency, patterns, etiologies, and costs of unplanned readmissions after left ventricular assist device implantation.

Methods: Between April 2012 and September 2016, 99 unplanned readmissions of a total of 50 consecutive bridge-to-transplant patients (45 males, 5 females; mean age 46.9±10.3 years; range, 19 to 67 years) who were successfully discharged after left ventricular assist device implantation were retrospectively analyzed. Patient demographic data, hemodynamic measurements before implantation, and readmissions after discharge were recorded. Hospitalizations due to major problems which were unable to be managed in routine outpatient clinic were accepted as unplanned readmissions. Survival analysis was performed.

Results: The readmission rate was 1.7 per year after discharge. Survival of patients who were readmitted within the first 90 days was found to be significantly lower than those without early readmission. The most common reasons of readmissions during follow-up were major infection (23.2%), neurological dysfunction (22.2%), cardiac causes (12.1%), bleeding (11.1%), and device malfunction (10.1%). Neurological dysfunctions (82,005 USD) and device malfunctions (73,300 USD) caused the highest economic burden.

Conclusion: Among patients with a left ventricular assist device, hospital readmissions are common. Development of preventive strategies as well as effective treatment methods focused on longterm adverse events is critical to reduce the frequency and costs of hospital readmissions.
