Although in vitro and primate orthotopic transplant experiments have
suggested the superiority of University of Wisconsin solution (UWS)
compared with crystalloid cardioplegia and saline solution storage for
hypothermic heart preservation, concerns about the viscosity and the high
potassium concentration of UWS have precluded its use in human cardiac
transplantation. To test the safety and efficacy of UWS, 16 patients
received hearts arrested with, flushed with, and stored in UWS at 4 degrees
C for a mean ischemic time of 153.3 +/- 30.7 minutes. After reperfusion,
the hearts contracted vigorously and attained a stable sinus rhythm within
4.0 +/- 2.4 minutes, and the patients were weaned from bypass in 24.5 +/-
8.0 minutes. There was no evidence of acute or chronic ischemic myocardial
injury by enzymatic analysis, electrocardiography, or biopsy specimen
histology. The results suggest UWS can be safely used, within currently
accepted limits of donor ischemic time, to arrest and preserve human hearts
for transplantation. Further studies of preservation are required to
compare UWS with crystalloid cardioplegia and saline solution storage and
to test the ability of UWS to prolong the period of safe donor hypothermic
ischemia in clinical heart transplantation.
