[The effect of the graft contraction rate on the intraoperative hemodynamics in orthotopic heart transplantation].
Intraoperative hemodynamics has been studied during orthotopic heart transplantation (OHT) in 36 recipients, aged 14 to 56 years, with spontaneous contractions of the graft. It has been established that patients with HR greater than 110 beats per min were in most cases characterized by normal central venous pressure (CVP) and venous blood oxygenation parameters. In lower HR, CVP is considerably higher and the indexes characteristic of the adequacy of cardiac output to body oxygen requirements are deteriorated. Right after OHT there is a reverse dependence between HR and CVP, with the lowest CVP values corresponding to HR intervals 101-120 and 121-140 per min. It has been concluded that tachycardia in the intraoperative period ensures a more effective function of the transplanted heart.
