A functioning intrapericardial paraganglioma (pheochromocytoma).

Y Shimoyama, K Kawada, H Imamura

    British Heart Journal
    |April 1, 1987
    PubMed
    Summary

    A rare functioning intrapericardial paraganglioma (pheochromocytoma) was successfully removed from the aorta root. The complex tumor resection was achieved using cardiopulmonary bypass without causing cardiac arrest.

    Area of Science:

    • Cardiovascular Surgery
    • Surgical Oncology
    • Endocrinology

    Background:

    • Intrapericardial paragangliomas are rare tumors arising from chromaffin cells within the pericardium.
    • These tumors, often presenting as pheochromocytomas, can be challenging due to their location and potential for catecholamine release.
    • Surgical management is typically required for symptomatic or large tumors.

    Observation:

    • A case of a functioning intrapericardial paraganglioma is presented.
    • The tumor was precisely located at the aortic root, directly over the right coronary artery.
    • It was noted to be adherent to the right ventricular wall, indicating significant local infiltration.

    Findings:

    • The intrapericardial paraganglioma was successfully excised.
    • The surgical procedure was performed using total cardiopulmonary bypass.
    • Crucially, cardiac arrest was avoided throughout the operation, preserving hemodynamic stability.

    Implications:

    • This case highlights the feasibility of complex tumor resections in the challenging intrapericardial space.
    • Successful surgical removal of pheochromocytomas can resolve associated hormonal imbalances and reduce cardiovascular risks.
    • The described technique demonstrates a viable approach for managing similar rare cardiac and aortic tumors.
