Fatty Infiltration of Right Ventricle (Adipositas Cordis): An Unrecognized Cause of Early Graft Failure After Cardiac Transplantation

Abstract

Fatty infiltration of the right ventricle is usually an incidental finding at post-mortem, but may have clinical significance at times of physiologic stress. We report a case of fatal right ventricular dysfunction immediately after cardiac transplantation secondary to massive fatty infiltration of the donor right ventricle. Ante-mortem diagnosis of fatty infiltration may be difficult to determine despite non-invasive cardiac evaluation. If the diagnosis of fatty infiltration is suspected at time of donor harvest, the relative risks and benefits of proceeding with transplantation should be carefully assessed.
