    Radiation therapy for intrathoracic and breast malignancies may lead to increased transvalvular gradients in patients with bioprosthetic heart valves.

  • 2

    A study of 23 patients showed significant increases in transvalvular gradients post-radiation therapy compared to matched controls.

  • 3

    Total radiation dose and mean heart radiation dose were significant predictors of increased transvalvular gradients within 12 months post-RT.

  • 4

    No patients in the study required re-intervention during the follow-up period despite observed changes in transvalvular gradients.

  • 5

    The findings suggest a need for long-term surveillance of bioprosthetic valve function in patients undergoing chest radiation therapy.
