Interventional Treatment of LVAD Outflow Graft Stenosis by Introduction of Bare Metal Stents.

Left ventricular assist device outflow graft stenosis is a rare but life-threatening complication of mechanical cirulatory support therapy. Current treatment modalities (pump exchange or systemic thrombolytic therapy) are associated with significant mortality and morbidity. Implantation of bare metal stents within the stenosed outflow graft is an alternative. Herein, we describe a series of three cases with successful stent placement. This seems to be safe and successful; however, correct and early diagnosis of outflow stenosis can be challenging. Information provided by the HeartWare ventricular assist device (HVAD) logfiles is extremely helpful for diagnosis.
