Dual HeartMate 3 total artificial heart implantation for cardiac sarcoma presents challenging hemodynamic management.
Case Report (n=1)
Implantation of two HeartMate 3 devices as a total artificial heart after total cardiectomy is feasible but presents significant hemodynamic management challenges.
Demands vigilant hemodynamic management with dual HeartMate 3 total artificial heart; hypothesis-generating for rare post-cardiectomy sarcoma applications.
We present the case of a 34-year-old patient with an unresectable cardiac sarcoma who underwent a total cardiectomy followed by implantation of 2 HeartMate 3 devices in a total artificial heart configuration. Surgical treatment of cardiac sarcomas ranges from palliative debulking to heart transplantation. In contrast to conventional total artificial heart placement, complete removal of both atrioventricular connections was mandated by the underlying pathologic process. Hemodynamic performance of 2 continuous flow pumps in the absence of native atria and the heart reservoir function depends on balancing preload, afterload, and individual pump rotations. The unreliability of conventional monitoring parameters in this clinical scenario makes hemodynamic management challenging.

Gašparović et al. (2025) conducted a case report in Unresectable cardiac sarcoma (n=1). Implantation of 2 HeartMate 3 devices in a total artificial heart configuration after total cardiectomy was evaluated. Implantation of two HeartMate 3 devices in a total artificial heart configuration after total cardiectomy for cardiac sarcoma presents challenging hemodynamic management.
