OBJECTIVEAs the use of left ventricular assist devices (LVADs) has expanded, cerebrovascular complications have become an increasing source of morbidity and mortality in this population. Intracranial hemorrhage (ICH) in particular remains a devastating complication in patients who undergo LVAD placement with no defined management guidelines. The authors therefore reviewed surgical and anticoagulation management and outcomes of patients with LVADs who presented to their institution with ICH.METHODSThis retrospective cohort study assessed outcomes of patients who underwent LVAD placement at a single institution between 2007 and 2016 and in whom imaging demonstrated ICH.RESULTSDuring the study period, 281 patients had a HeartMate II or HeartWare LVAD placed. There were 37 episodes of ICH (recurrent in 3 cases). ICHs were categorized as intraparenchymal hemorrhage (IPH; n = 22, 59%), subdural hemorrhage (SDH; n = 6, 16%), and subarachnoid hemorrhage (SAH; n = 9, 24%). Neurosurgical intervention was deemed necessary in 27.3%, 66.7%, and 0% of patients with IPH, SDH, and SAH, respectively; overall survival > 30 days for each type of hemorrhage was 41%, 83%, and 89%, respectively. No patients had LVAD thrombus as a result of reversal of anticoagulation. Combined with prior reports, good outcomes are seen more often following surgery for SDH than for IPH (57% vs 7%, p = 0.004) in patients who underwent VAD placement.CONCLUSIONSPatients with IPH who undergo LVAD placement have poor outcomes regardless of anticoagulation reversal or neurosurgical intervention, whereas those with SDH may have good outcomes with medical and surgical intervention, and those with SAH appear to do well without anticoagulation reversal or surgery. When needed, anticoagulation reversal was not associated with an increase in LVAD thrombosis in this series.

Background and Purpose: Severity-based assessment tools may assist in prehospital triage of patients to comprehensive stroke centers (CSCs) for endovascular thrombectomy (EVT), but criticisms regarding diagnostic inaccuracy have not been adequately addressed. This study aimed to quantify the benefits and disadvantages of severity-based triage in a large real-world paramedic validation of the Ambulance Clinical Triage for Acute Stroke Treatment (ACT-FAST) algorithm. Methods: Ambulance Victoria paramedics assessed the prehospital ACT-FAST algorithm in patients with suspected stroke from November 2017 to July 2019 following an 8-minute training video. All patients were transported to the nearest stroke center as per current guidelines. ACT-FAST diagnostic accuracy was compared with hospital imaging for the presence of large vessel occlusion (LVO) and need for CSC-level care (LVO, intracranial hemorrhage, and tumor). Patient-level time saving to EVT was modeled using a validated Google Maps algorithm. Disadvantages of CSC bypass examined potential thrombolysis delays in non-LVO infarcts, proportion of patients with false-negative EVT, and CSC overburdening. Results: Of 517 prehospital assessments, 168/517 (32.5%) were ACT-FAST positive and 132/517 (25.5%) had LVO. ACT-FAST sensitivity and specificity for LVO was 75.8% and 81.8%, respectively. Positive predictive value was 58.8% for LVO and 80.0% when intracranial hemorrhage and tumor (CSC-level care) were included. Within the metropolitan region, 29/55 (52.7%) of ACT-FAST-positive patients requiring EVT underwent a secondary interhospital transfer. Prehospital bypass with avoidance of secondary transfers was modeled to save 52 minutes (95% CI, 40.0–61.5) to EVT commencement. ACT-FAST was false-positive in 8 patients receiving thrombolysis (8.1% of 99 non-LVO infarcts) and false-negative in 4 patients with EVT requiring secondary transfer (5.4% of 74 EVT cases). CSC bypass was estimated to over-triage 1.1 patients-per-CSC-per-week in our region. Conclusions: The overall benefits of an ACT-FAST algorithm bypass strategy in expediting EVT and avoiding secondary transfers are estimated to substantially outweigh the disadvantages of potentially delayed thrombolysis and over-triage, with only a small proportion of EVT patients missed.
