Devices to decrease stroke risk

Area of Science:

• Cardiovascular Medicine
• Neurology
• Medical Devices

Background:

• Stroke is a primary cause of death and disability in the U.S.
• Cryptogenic stroke accounts for up to 40% of all strokes.
• Patent foramen ovale (PFO) and left atrial appendage (LAA) are frequently linked to stroke events.

Observation:

• Ischemic strokes are often associated with atrial fibrillation.
• Atrial fibrillation can lead to clot formation in the left atrial appendage.
• Patent foramen ovale can allow clot passage from the venous to the arterial system.

Findings:

• Devices are being developed to occlude PFO.
• Devices are also designed to occlude the LAA.
• Early data indicate these devices can reduce stroke risk.

Implications:

• Interventional cardiology is becoming crucial for stroke prevention.
• Minimally invasive device-based therapies offer new treatment avenues.
• Further research will define the long-term efficacy and safety of these interventions.
