Insights
Developing a multidisciplinary stroke pathway significantly reduced time to CT imaging for children on mechanical circulatory support (MCS). This pathway addresses critical care gaps for pediatric ventricular assist device (VAD) patients experiencing stroke.
Area of Science:
- Pediatric Neurology
- Cardiovascular Surgery
- Critical Care Medicine
Background:
- Mechanical circulatory support (MCS), particularly ventricular assist devices (VADs), is a major cause of stroke in children.
- Existing pediatric stroke guidelines are often inadequate for VAD-supported patients.
- Timely and effective acute stroke care is challenging in this population due to specific barriers.
Purpose of the Study:
- To develop a multidisciplinary pathway for acute stroke care in pediatric VAD patients.
- To evaluate the early performance of this pathway in expediting stroke diagnosis and management.
- To address identified barriers in stroke recognition and treatment for these children.
Main Methods:
- Convened multidisciplinary stakeholders (pediatric heart failure, critical care, neurology, radiology, neurosurgery, pharmacy, VAD experts).
- Identified challenges including delayed recognition, unclear imaging protocols, and antithrombotic reversal strategies.
- Developed four specific acute stroke pathways for different clinical scenarios (pre-diagnosis, AIS, ICH, SDH).
Main Results:
- Implemented stroke pathway significantly decreased median time-to-first-CT image by 43 minutes (from 66 to 23 minutes, P < 0.001).
- Proportion of patients receiving a CT within 30 minutes increased from 0% to 67% (P < 0.001).
- Multidisciplinary consensus was achieved despite identified challenges.
Conclusions:
- A rapid stroke management pathway can be developed for children on VAD support.
- The pathway effectively addresses key barriers to timely stroke care.
- Pathway implementation led to significantly shorter time to initial CT imaging, improving diagnostic speed.
Abstract:
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.

Regulation of Stroke Volume
Preload refers to the degree of stretch on the heart before it contracts. It's analogous to the stretching of a rubber band; the more it's stretched, the more forcefully it snaps back. This concept is encapsulated in the Frank-Starling law of the...
