Cardioembolic Stroke in Patient With Transcatheter Occluded Left Atrial Appendage

Area of Science:

• Cardiology
• Neurology
• Medical Imaging

Background:

• Left atrial appendage (LAA) closure is an alternative to anticoagulation for stroke prevention in atrial fibrillation.
• Transcatheter LAA obliteration aims to reduce thromboembolic events.

Observation:

• A patient undergoing LAA transcatheter obliteration experienced a subsequent cerebral ischemic event.
• Transesophageal echocardiography (TEE) was utilized for procedural guidance and follow-up.

Findings:

• TEE successfully identified and accurately defined device-related leakage from the occluded LAA.
• The identified LAA device leakage was a key finding in the post-procedural ischemic event.

Implications:

• Accurate imaging is crucial for assessing the efficacy and potential complications of LAA closure devices.
• Understanding device leakage mechanisms can inform future LAA obliteration strategies and patient selection.
