Aim of our clinical study was evaluation own initial experience of high-urgency ortotopic heart transplantation (OHT) in recipients, who were bridged on peripheral Vena-Arterial Extracorporeal Membrane Oxygenation (VA ECMO). Materials and methods. In this study was included 17 patients (14/3 M/F, age 16–66 (40.1 ± 4.2 yrs)) who underwent OHT while on peripheral ECMO support. In all cases we used peripheral surgical can- nulation technique via femoral vessels – arterial cannula 15–19 Fr, venous cannula – 21–25 Fr, arterial cannula or vascular catheter 8–10 Fr for anterograde leg’s perfusion. Results. Duration Vena-Arterial Extracorporeal Membrane Oxygenation before OHT was 81 ± 17 h. VA ECMO support was blood flow 4.8 ± 0.6 l/min or 2.63 ± 0/04 l/min/m2, gas flow 4.8 ± 0.6 l/min, FiO2 0.86 ± 0.07. Vena-Arterial Extracorporeal Membrane Oxygenation support was continued in “protective mode” (blood flow 1.9 ± 0.2 l/min) 4.3 ± 0.5 days after OHT. Thirteen pa- tients (76.4%) were weaned from VA ECMO successfully and survived to be discharged. ICU and hospital LOS after orthotopic heart transplantation was respectively 6.7 ± 0.8 and 32.3 ± 4.6 days in group of survived patients. The reasons of a lethal outcome (n = 4, 23.5%) were sepsis and multiorgan failure (n = 3), sudden cardiac arrest (n = 1). Conclusion. Vena-Arterial Extracorporeal Membrane Oxygenation is a favorable short-term method of circulatory support in patients who needed in high-urgency heart transplantation.
