'Giant fleshy leaflet myxoma'

Area of Science:

• Cardiology
• Neurology
• Pathology

Background:

• Cardiac myxomas are the most common primary heart tumors, often presenting with embolic or obstructive symptoms.
• Neurological deficits can be the initial manifestation of cardiac myxomas due to systemic embolization.

Observation:

• A 25-year-old woman presented with acute left-sided hemiparesis.
• Transthoracic echocardiography revealed a large, mobile mass attached to the anterior mitral leaflet, prolapsing into the left ventricle during diastole.
• Cardiac auscultation noted an additional heart sound suggestive of valvular obstruction.

Findings:

• Histopathological examination confirmed the mass as a myxoma.
• Surgical excision of the myxoma and mitral valve repair were performed.
• Post-operative follow-up showed complete resolution of symptoms and no tumor recurrence at six months.

Implications:

• This case highlights the importance of considering cardiac myxoma in young patients with unexplained neurological symptoms.
• Timely diagnosis and surgical intervention are crucial for preventing embolic events and ensuring favorable outcomes.
• Comprehensive echocardiographic evaluation is essential for characterizing cardiac masses and guiding management.
