Mechanical circulatory support is successfully applied to patients with low cardiac output. The MEDOS/HIA‐System provides pulsatile ventricular assistance for pediatric and adult patients. Our experience with 13 consecutive patients with the MEDOS is reported. Perioperative survival was 84.6%, complications occurred in 61% (31% thrombembolism, 23% rethoracotomy, 7% infections). Mean duration of support was 17.6 ± 14.6 days (1–45 days). Bilirubin decreased from 3.9 ± 2.3 to 2.7 ± 1.6 mg/dL; creatinine from 1.6 ± 1 to 1.4 ± 0.8 mg/dL; lactate from 5.8 ± 4.2 to 1.7 ± 1.5 ( P = 0.027; Wilcoxon). All patients who underwent subsequent heart transplantation (6 of 13; 46%) were discharged from hospital. For 38.5% of the patients no organ offer was received. Mechanical circulatory support with the MEDOS/HIA‐System can be performed successfully for bridging to transplantation. Secondary organ functions improve under this pulsatile circulatory assistance. Hemorrhage and thromboembolic events are the most frequent complications.
