Papillary fibroelastoma in the left atrium.

Area of Science:

• Cardiology
• Neurology
• Pathology

Background:

• Papillary fibroelastomas are rare cardiac tumors, typically found on valves.
• Left atrial tumors are uncommon and can lead to embolic complications.
• Cerebral embolism can manifest as stroke symptoms like slurred speech and weakness.

Observation:

• A 71-year-old woman with angina presented with acute stroke symptoms.
• Imaging revealed significant coronary artery disease and a left atrial mass.
• Cerebral lesions consistent with embolism were noted in the left middle cerebral artery territory.

Findings:

• The left atrial mass was surgically excised and identified as a papillary fibroelastoma.
• The patient underwent coronary artery bypass grafting.
• The presumed source of cerebral embolism was thrombus formation on the fibroelastoma.

Implications:

• This case highlights the uncommon presentation of papillary fibroelastoma leading to stroke.
• Early diagnosis and surgical intervention are crucial for preventing recurrent embolic events.
• Comprehensive management involving cardiac tumor excision and revascularization is effective.
