Abstract:
AIM: The aim of this study was to investigate the hemodynamic characteristics of the denervated orthotopic transplanted hearts. METHODS: Eighteen patients with end - stage cardiopathy underwent orthotopic cardiac transplantation received immunosuppressive induction therapy. The changes of hemodynamics were closely monitored during the perioperative period and the periodic check-up of echocardiogram and electrocardiograph were followed up in the postoperative long-term period. RESULTS: All recipients were received vasoactive drug and active diuretic therapy during the perioperative period. An increase in central venous pressure in concomitance with decrease in cardiac output, cardiac index and mixed venous oxygen saturation within 24 to 48 hours and tend to stable 48 hours postoperation were detected. In the follow - up period, the cardiac functions of allografts were all recovered well. No recipient complained angina pectoris. CONCLUSIONS: The hemodynamic characteristics and clinical pharmacological therapeutic implications of cardiac denervation are very unique. Rational application of inotropic support and diuretic therapy and vasodilatation combined with prudent administration of some agents, which affect the physiology of denervated heart, are the most effective measures for the prevention of postoperative complications of cardiac allograft.
