N2 - Background: The United Network of Organ Sharing (UNOS) heart allocation policy designates patients on ECMO or with nondischargeable, surgically implanted, nonendovascular support devices (TCS-VAD) to higher listing statuses. Objectives: This study aimed to explore whether temporary circulatory support-ventricular assist devices (TCS-VAD) have a survival advantage over extracorporeal membrane oxygenation (ECMO) as a bridge to transplant. Methods: The UNOS database was used to conduct a retrospective analysis of adult heart transplants performed in the United States between 2005 and 2017. Survival analysis was performed to compare patients bridged to transplant with different modalities. Results: Of the 24,905 adult transplants performed, 7,904 (32%) were bridged with durable left ventricular assist devices (LVADs), 177 (0.7%) with ECMO, 203 (0.8%) with TCS-VAD, 44 (0.2%) with percutaneous endovascular devices, and 8 (0.03%) with TandemHeart (LivaNova, London, United Kingdom). Unadjusted survival at 1 and 5 years post-transplant was 90 ± 0.4% and 77 ± 0.7% for durable LVAD, 84 ± 3% and 71 ± 4% for all TCS-VAD types, 79 ± 9% and 73 ± 14% for biventricular TCS-VAD, and 68 ± 3% and 61 ± 8% for ECMO. After propensity-matched pairwise comparisons were made, survival after all TCS-VAD types continued to be superior to ECMO (p = 0.019) and similar to LVAD (p = 0.380). ECMO was a predictor of post-transplant mortality in the Cox analysis compared with TCS-VAD (hazard ratio 2.40; 95% confidence interval: 1.44 to 4.01; p = 0.001). Conclusions: Post-transplant survival with TCS-VAD is superior to ECMO and similar to LVAD in a national database.
