[Utility of transesophageal echocardiography in young patients with cryptogenic stroke and low cardiovascular risk]

Area of Science:

• Cardiology
• Neurology
• Diagnostic Imaging

Background:

• Stroke is a leading cause of death and disability.
• Cryptogenic stroke, accounting for up to 40% of strokes in young adults, often lacks an identifiable cause.
• Limited therapeutic options previously existed for cryptogenic stroke patients.

Purpose of the Study:

• To evaluate the diagnostic yield of transesophageal echocardiography (TEE) in identifying cardiac sources of stroke in young patients.
• To assess the impact of TEE findings on therapeutic management.

Main Methods:

• A study involving 100 consecutive patients aged 55 or younger with cryptogenic stroke.
• Transesophageal echocardiography (TEE) was performed on all participants.

Main Results:

• TEE revealed a cardiac source of stroke in 51% of patients.
• Abnormalities included patent foramen ovale (PFO), atrial septal aneurysm (ASA), cardiac masses, and severe aortic atherosclerotic plaques.
• Therapeutic management was altered in 46 patients (90.2% of those with abnormal TEE findings).

Conclusions:

• Transesophageal echocardiography (TEE) is a valuable tool for diagnosing cardiac causes of stroke in young adults.
• Identifying these cardiac sources enables significant changes in patient treatment strategies.
• TEE improves the management of cryptogenic stroke in younger populations.
