Primary cardiac angiosarcoma resection combined with right coronary artery bypass grafting

Area of Science:

• Cardiovascular Surgery
• Surgical Oncology
• Cardiac Pathology

Background:

• Primary cardiac tumors are rare, with angiosarcoma being an aggressive malignancy.
• Cardiac tamponade can be a presenting symptom of advanced cardiac tumors.
• Early diagnosis and aggressive surgical intervention are crucial for managing primary cardiac malignancies.

Observation:

• A 41-year-old woman presented with symptoms suggestive of cardiac tamponade.
• Diagnostic imaging revealed a primary malignant tumor in the right atrium without distant metastasis.
• The tumor involved the right atrial wall, right coronary artery, and sinus node.

Findings:

• Complete surgical resection of the right atrial angiosarcoma was achieved.
• Reconstruction involved coronary artery bypass grafting and equine pericardium graft for the right atrial wall.
• Pathological examination confirmed angiosarcoma as the final diagnosis.

Implications:

• This case demonstrates the feasibility of aggressive surgical management for extensive right atrial angiosarcoma.
• Successful reconstruction techniques, including bypass grafting and pericardial grafting, are vital for post-resection function.
• Adjuvant radiotherapy may play a role in managing residual disease or preventing recurrence.
• Long-term follow-up is essential to monitor for recurrence of this rare and aggressive cardiac tumor.
