Neurologic complications of valvular heart disease

Area of Science:

• Cardiology
• Neurology
• Vascular Medicine

Background:

• Valvular heart disease (VHD) is a significant cause of neurologic complications, with cerebral embolism being the most frequent.
• Thrombus formation in VHD stems from valvular surface abnormalities and altered cardiac structure/function, including chamber enlargement and arrhythmias.
• Prosthetic heart valves, especially mechanical ones, increase thromboembolism risk, necessitating anticoagulation.

Purpose of the Study:

• To review the spectrum of neurologic complications associated with valvular heart disease.
• To discuss the role of anticoagulation in preventing and managing these complications.
• To highlight the importance of understanding the natural history of VHD and its treatments for effective patient management.

Main Methods:

• Literature review focusing on neurologic complications of VHD.
• Analysis of mechanisms leading to thromboembolism and hemorrhage in VHD patients.
• Discussion of treatment strategies, including anticoagulation, and their associated risks.

Main Results:

• Cerebral embolism is a common neurologic complication of VHD.
• Infective endocarditis and nonbacterial thrombotic endocarditis are other VHD-related conditions causing neurologic issues.
• Complications of anticoagulation therapy represent another source of neurologic problems in VHD patients.

Conclusions:

• Effective management of VHD-related neurologic complications necessitates a comprehensive understanding of their causes.
• Balancing the risks of VHD and its treatments, particularly anticoagulation, is crucial for optimal patient outcomes.
• Further research into the natural history and management strategies for these complex cases is warranted.
