Multidisciplinary Stroke Pathway for Children Supported With Ventricular Assist Devices.

Mechanical circulatory support (MCS), including ventricular assist device (VAD) support, is a leading cause of stroke in children; however, existing pediatric stroke recommendations do not apply to many pediatric VAD patients. We sought to develop a multidisciplinary pathway to improve timely and effective acute stroke care and examine the early performance of the pathway in expediting stroke care. Stakeholders from pediatric heart failure, cardiac intensive care, neurology, interventional radiology, neuroradiology, neurosurgery, pharmacy, and adult VAD care convened at Stanford University in August 2017 to discuss the challenges of providing high-quality acute stroke care to children on VAD support, and to develop multidisciplinary acute stroke pathways. Stakeholders identified multiple barriers to providing timely acute stroke care to pediatric VAD patients. These include delayed recognition of stroke, and lack of clarity related to the optimal imaging technique, when to emergently reverse antithrombotic therapy (AT), pediatric indications for thrombectomy and cranial decompression, and strategies to avoid unnecessary serial CTS. Four stroke pathways were created including evaluation and management of the pediatric patient with (1) an acute neurologic change before an imaging diagnosis; (2) an arterial ischemic stroke (AIS); (3) an intracerebral hemorrhage (ICH); and (4) a subdural hematoma (SDH). With the implementation of the stroke pathway, the median time-to-first-CT image decreased by 43 minutes from 66 to 23 minutes ( P < 0.001) while the proportion with a CT within 30 minutes increased from 0% to 67% ( P < 0.001). Despite a variety of challenges, multidisciplinary consensus can be achieved on a rapid stroke management pathway for children on VAD support that addresses important barriers to timely stroke care. Although too few stoke events occurred to differentiate clinical outcomes, the time-to-first-CT image was significantly shorter after pathway implementation.
