Summary

Malignant mesenchymoma originating in the heart is exceptionally rare and typically has a poor prognosis. This case highlights a left atrial tumor causing heart failure and arterial embolization, successfully treated with surgery and chemotherapy.

Area of Science:

  • Cardiovascular Medicine
  • Oncology
  • Pathology

Background:

  • Primary malignant mesenchymoma of the heart is an exceedingly rare tumor.
  • These tumors are associated with a generally poor prognosis.

Observation:

  • A rare case of malignant mesenchymoma originating in the left atrium is presented.
  • The tumor extended into the right pulmonary veins and involved the abdominal aorta.
  • Clinical presentation included congestive heart failure, hemoptysis, and systemic arterial embolization.

Findings:

  • Echocardiography revealed a large left atrial mass extending into pulmonary veins.
  • Cardiac catheterization showed elevated pulmonary arterial wedge pressure, pulmonary hypertension, and aortic stenosis.
  • MRI with angiography identified a tumor mass on the abdominal aorta with iliac artery extension.

  • Pathological examination confirmed a malignant mesenchymoma with diverse sarcoma cell types.

    • Implications:

    • This case underscores the diagnostic challenges and aggressive nature of primary cardiac malignant mesenchymoma.
    • Successful surgical resection and adjuvant chemotherapy offer a potential treatment strategy.
    • Further research into the management of these rare cardiac tumors is warranted.
