The first experience with clinical use of monocuspid xenopericardial transplants

: The article discusses experience in radical correction of Fallot's tetrad with hypoplasia of the pulmonary trunk in 43 patients by means of plastics with monocuspid xenopericardial grafts (MXG). Their processing was based on enzymatic chemical treatment of the xenopericardium. The function of the MXG was evaluated with quantitative registration of regurgitation by the method of dilution of electroimpedence indicators. Mortality in the group of patients with MXG was 8.0%, which did not differ from that in the group of patients with satisfactorily developed pulmonary trunk and its branches, and characterized the promising character of the use of this method of pulmonary trunk plastics.
