Survival of a patient following initial left ventricular assist device implantation and two successive left ventricular assist device exchanges: case report.

BACKGROUND

Initially conceptualized as a bridge to heart transplantation, the left ventricular assist device (LVAD) has become an important option for improving survival in patients with severe heart failure and poor prognosis.

CASE SUMMARY

We report the case of a patient suffering from severe chronic heart failure, complicated by ST-elevation myocardial infarction due to left main coronary artery stenosis (NYHA IV, INTERMACS profile 1). Despite support with veno-arterial extracorporeal membrane oxygenation, inotropes, and catecholamine therapy, the patient's cardiac function did not recover sufficiently. Consequently, the decision was made to proceed with LVAD implantation as destination therapy. The initial LVAD implantation was uneventful, and the patient received anticoagulant therapy according to standard operating procedure. However, pump thrombosis occurred on the first post-operative day, necessitating an LVAD exchange. Following an extended stay in the cardiac surgery intensive care unit, the patient was eventually discharged. Approximately 15 months later, the patient developed a driveline infection, involving most of the intrapericardial components of the LVAD. A second LVAD exchange was required, and the patient received a third LVAD. To mitigate the risk of recurrent infection, suppressive antibiotic therapy with ampicillin/sulbactam was initiated.

DISCUSSION

This is the first reported case of a patient surviving three LVAD implantations and highlights an instance of off-label use of lifelong antibiotic therapy following a driveline infection.
