A recent study from the University of Minnesota using the Asporto heart preservation device was published in a nationally recognized peer reviewed journal. The study demonstrated that intermittent antegrade cardioplegia maintains a significantly higher pH in donor hearts. The study involved a series of animal hearts preserved using the conventional method of donor heart transportation (an insulated container) vs. hearts preserved in the Asporto heart preservation device. Use of the device limited the rapid formation of acidosis that causes irreversible heart muscle damage that occurs during the conventional method. (Progress in Transplantation, 2008; 18(2):127-133)
