Abstrakt: | Background: We investigated the synergistic effect of the new cone-bearing design of Jarvik 2000 (Jarvik Heart Inc., NY) together with a minimally-invasive approach to outcomes of LVAD patients. Methods: We retrospectively reviewed all patients from 5 institutions involved in the Jarvik 2000 Italian Registry, from October 2008 to October 2016. Patients were divided into three groups according to pump design and implantation technique: pin-bearing design and conventional approach (Group 1); cone-bearing and conventional approach (Group 2); cone-bearing and minimally-invasive implantation (Group 3). Results: A total of 150 adult patients with end-stage heart failure were enrolled: 26 subjects in Group 1, 74 in Group 2, and 50 in Group 3. Nineteen patients (73%) in Group 1, 51 (69%) in Group 2, and 36 (72%) in Group 3 were discharged. During follow-up, 22 patients underwent transplantation, while in 3 patients the LVAD was explanted. The overall 1-year survival was 58 ± 10%, 64 ± 6%, and 74% ± 7% in Groups 1, 2, and 3, respectively (p = 0.034). The competing-risks-adjusted cumulative incidence rate for adverse events was 42.1 [27-62.7] per 100 patient-years in Group 1, 35.4 [25.3-48.2] in Group 2, and 22.1 [12.4-36.4] in Group 3 (p = 0.046 for Group 1 vs. 3). Conclusions: The association of the modern cone-bearing configuration of Jarvik 2000 and minimally invasive surgery improved survival and minimized the risk for cardiovascular events, as a result of combining technology and technique.
