Neurological complications associated with left ventricular assist device therapy

Area of Science:

• Cardiology
• Neurology
• Medical Devices

Background:

• Neurological complications, particularly stroke, are prevalent in adult patients with left ventricular assist devices (LVADs), occurring in up to 25% of cases.
• The increasing use of LVADs necessitates a better understanding of associated hematologic and hemodynamic changes, risk factors for neurological events, and effective mitigation strategies.

Purpose of the Study:

• To review and synthesize the current literature on risk factors and mitigation strategies for stroke in patients following LVAD implantation.
• To highlight the need for improved prediction models and standardized management protocols for neurological complications in the LVAD population.

Main Methods:

• A comprehensive literature search was conducted on PubMed using terms related to LVADs and stroke, including risk factors.
• Results were filtered for human studies to focus on relevant clinical data.

Main Results:

• The literature review identified key risk factors contributing to stroke in LVAD patients, though consensus on prediction remains limited.
• Current research has identified some risk factors, but further investigation is needed to develop reliable predictive models.

Conclusions:

• There is a lack of consensus on accurately predicting stroke risk in the LVAD population.
• Further research is warranted to develop robust predictive models and standardized treatment protocols, including individualized anticoagulation strategies, to mitigate stroke risk while balancing bleeding and thrombosis.
• A multidisciplinary approach is essential for standardizing the care of LVAD patients experiencing neurological complications.
