Coil embolization of coronary supply to a cardiac metastasis

Area of Science:

• Interventional Radiology
• Cardiology
• Oncology

Background:

• Cardiac metastases are rare but associated with poor prognosis.
• Uterine leiomyosarcoma can rarely metastasize to the heart.
• Palliative treatment options for cardiac metastases are limited.

Observation:

• A patient with a cardiac metastasis from uterine leiomyosarcoma was identified.
• Tumor-related coronary arteries supplying the metastasis were targeted.

Findings:

• Coil embolization of the tumor-feeding coronary arteries was technically successful.
• This procedure effectively interrupted the coronary blood supply to the cardiac metastasis.

Implications:

• Percutaneous coronary embolization may be a viable palliative therapeutic strategy for cardiac metastases from highly malignant tumors.
• This approach could improve quality of life for select patients by managing tumor burden in the heart.
• Further research is warranted to establish the safety and efficacy of this technique in a larger cohort.
