Neurological Dysfunction During Contemporary Magnetically Levitated Left Ventricular Assist Device Support for Advanced Heart Failure
- Retrospective cohort study
- multicenter
Authors' conclusion
Stroke and nonstroke NAEs are incurred by a similar proportion of patients, and both are associated with substantially reduced survival. Consequently, stroke and nonstroke NAEs should be given comparable weight with universal nomenclature when evaluating the safety of durable LVADs.
