Primary osteosarcoma of left atrium: complete surgical excision

Area of Science:

• Cardiology
• Oncology
• Thoracic Surgery

Background:

• Primary cardiac tumors are rare, with osteosarcoma being an exceptionally uncommon diagnosis.
• Left atrial osteosarcoma can present with symptoms mimicking severe congestive heart failure.

Observation:

• A case report detailing a patient with primary osteogenic sarcoma originating in the left atrium.
• The patient exhibited significant clinical manifestations of severe congestive heart failure.

Findings:

• Surgical intervention involved excision of the posterior atrial wall and left pulmonary veins.
• Reconstruction of the atrial defect was achieved using the left atrial appendage.
• The left pulmonary artery was ligated, followed by a subsequent pneumonectomy.

Implications:

• This case highlights the challenges in diagnosing and surgically managing rare primary cardiac tumors.
• Despite aggressive surgical treatment, the prognosis for advanced osteogenic sarcoma of the heart remains poor due to metastatic potential.
