Heart metastases from gastric sarcoma. A case report

Area of Science:

• Cardiology
• Oncology
• Radiology

Background:

• Metastatic gastric sarcoma is a rare condition.
• Cardiac involvement by tumors is uncommon.

Observation:

• A 29-year-old man presented with heart failure due to gastric sarcoma metastasizing to the heart.
• Tumors prolapsed into the left atrium, obstructing the mitral valve orifice.
• Two-dimensional echocardiography facilitated diagnosis.

Findings:

• The patient underwent two non-curative surgeries for the left atrial mass.
• The patient died of refractory heart failure 9 months after symptom onset.
• This case highlights secondary intracavitary tumors causing mitral valve obstruction.

Implications:

• Two-dimensional echocardiography is the preferred diagnostic tool for cardiac tumors.
• Early diagnosis and management of cardiac metastases are critical.
• Further research into managing rare cardiac sarcomas is warranted.
