Comparison of UW vs. HTK Solution for Myocardial Protection in Heart Transplantation H. Reichenspurner et al, Transp Int (1994) 7 (Supp 1) S481–S484
This studies aim was to investigate the protective effect of UW in heart transplant. A retrospective comparative study with Custodiol® HTK was done with 160 patients with HTK protection and 50 patients with a transplanted heart protected with UW.
A Comparison of Intracellular Solutions for Donor Heart Preservation Paul J. Hendry et al, J Thoracic Cardiovascular Surgery, 1993;105:667-73
This study compared the effects of Euro-Collins, University of Wisconsin and Bretschneider’s (Custodiol® HTK) solutions with the use of an in vitro human right atrial muscle preparation to assess recovery of function after a 24-hour period of simulated cardiac arrest. Bretschneider’s solution resulted in greatly improved recovery compared to E-C and UW solutions. UW was also found to be better than E-C. Recovery of developed force was affected by temperature for EC and UW, but not for Bretschneider’s. The author noted this is of importance because uniform temperatures are seldom maintained during heart transplantation. Bretschneider’s has a very high buffering capacity, which the author speculates may be beneficial for long-term preservation.

This study evaluates the myocardial protection of Custodiol® HTK to Celsior in cases with extended cold storage in a rat model. The markers measured to analyze graft injury were tissue adenosine triphosphate (ATP) levels, as well as serum creatine phosphokinase (CPK), serum troponin I, graft-infiltrating cells, graft mRNA levels for inflammatory mediators. Results indicated that HTK was found to provide “superior protective effects against prolonged cold ischemia” in heart transplant.

SAITOH, Y. et al, Heart Preservation in HTK Solution: Role of Coronary Vasculature in Recovery of Cardiac Function, Annals of Thoracic Surgery 2000, 69:107-112
This study investigates Custodiol® HTK versus UW in terms of protecting the coronary vasculature. Rat hearts were arrested, stored in one of the two preservation solutions at 4 degrees Celsius for 8 hours and then reperfused. Coronary vascular responsiveness was examined before flushing, before storage, after storage and after reperfusion. The authors found that “HTK is superior to UW solution for cardiac preservation” by measuring pre- and post- storage ATP and ADP levels. Additionally, recovery of AF, CF, CO, RPP and LV dp/dt were found to be significantly better in the HTK group.
