Abstract TMP64: Outcomes After Mechanical Thrombectomy In Patients With Left Ventricular Assist Devices

Background: Left ventricular assist devices (LVADs) are an established durable and lifesaving treatment option for patients with advanced heart failure. However, large vessel occlusions (LVOs) remain one of its most devastating embolic complications. Mechanical thrombectomy (MT) is safe and effective in the management of LVOs in the general population but LVO trials largely excluded patients on mechanical circulatory support and large-scale analyses of outcomes following these interventions in the LVAD population are lacking. Methods: Using the National Inpatient Sample (2012 - 2018) we identified all adult patients hospitalized with acute ischemic stroke (AIS). The presence of LVAD, the use of MT, and additional covariates were extracted. Descriptive statistics and multivariable regression models were used to compare outcomes following MT in patients with and without LVADs. Results: Of the 798,059 AIS hospitalizations identified, 366 occurred in patients with LVADs. LVAD patients were younger (mean age 59.6 [13.2] vs 70.1 [14.3], p Conclusion: Our data suggests MT is not a futile treatment approach in patients with LVADs and may result in similar rates of good outcomes. Additional research is needed to evaluate the long-term benefits of endovascular therapy after stroke in patients on LVAD support.
