Objective. To compare the cardioprotective effcacy of a preservation solution based on Krebs–Henseleit buffer and HTK solution in the model of heterotopic heart transplantation in rat.Design and methods. A study was conducted on 12 Wistar rats. The animals were divided into groups depending on the preservation solution used: 1) Krebs–Henseleit buffer-based solution (n = 7), 2) HTK (n = 5). Each experiment consisted of collecting donor heart, preserving it with an appropriate cardioplegic solution, heterotopic transplantation into a recipient rat followed by explantation and evaluation of left ventricular contractility using the Langendorff model and histochemical assessment of the irreversible myocardial damage. Coronary blood flow in the donor heart was assessed in vivo using ultrasound doppler flowmetry. After 3 hours, the donor heart was explanted and connected to the Langendorff apparatus to assess left ventricular contractility, and the myocardium was subjected to histochemical staining with 1 % triphenyltetrazolium chloride for the assessment of the irreversible myocardial damage.Results. In the group of Krebs–Henseleit buffer-based cardioplegic solution, 7 experiments were performed. Myocardial infarct size was 3,5 ± 1,2%, the coronary flow rate was 4,5 ± 1,3 ml/min, and the developed left ventricular pressure of the donor heart was 70 ± 6,3 mmHg at diastolic left ventricular pressure of 10 mmHg. In the HTK solution group (n = 5), in all of the experiments after the start of blood flow, the transplanted heart did not begin to contract, and all 5 hearts remained in an asystole state. Therefore, after the end of the 3-hour reperfusion period, the assessment of the contractility of the left ventricle using the Langendorff apparatus was not carried out. Coronary flow rate was only 0,4 ± 0,1 ml/min, probably resulting from inadequate cardioprotection with HTK solution. Due to the lack of adequate reperfusion, the accurate assessment of the irreversible myocardial damage was impossible in the HTK solution group.Conclusions. The technique of heterotopic heart transplantation in rats is adequate and informative for the study of ischemia-reperfusion myocardial damage as well as for the study of the effectiveness of cardioplegic and cardiac preservation solutions. Cardioplegic solution based on Krebs– Henseleit buffer demonstrated greater cardioprotective effectiveness in our model compared to HTK solution.
