Intracorporeal Biventricular Assist Devices Using the Heartware Ventricular Assist Device in Children

Heart Transplant Outcomes After Total Artificial Heart

BACKGROUND

We sought to compare heart transplant (HTX) outcomes from patients with a total artificial heart (TAH), biventricular assist device (BiVAD), or left ventricular assist device (LVAD) as a bridge to transplant (BTT). Interagency Registry for Mechanically Assisted Circulatory Support (INTERMACS)-Scientific Registry of Transplant Recipients (SRTR) created a dataset with TAH or durable mechanical circulatory support (MCS) who reached HTX between 2006 and 2015.

METHODS

The retrospective analysis compared TAH outcomes with those with a BiVAD or LVAD before HTX. The primary outcome was posttransplant survival at 1, 36, and 60 months. Secondary outcomes included simultaneous heart-kidney transplants, donor characteristics, and mortality risk factors. INTERMACS-SRTR cohort had, at the time of HTX, 2762 patients with LVAD; 205 BiVAD (139 durable and 66 temporary RVAD); 176 TAH (6 prior HeartMate II).

RESULTS

Sixty months after HTX, mortality rates were 16.5% in the total group: LVAD 15.2%, BiVAD 22.4%, and TAH 29%. Survival differed between the LVAD, the TAH, and BiVAD but not between the BiVAD and TAH groups. One-year survival and complication rates were similar across groups-there was no difference in survival by donor age in the overall cohort. There was a difference in TTD based on recipient age in the LVAD group but not in BiVAD or TAH groups. Occurrence of HTX-kidney and post-transplant dialysis were higher in the TAH versus LVAD and BiVAD groups.

CONCLUSIONS

The TAH is an efficacious BTT. Refinements in technology and patient selection may improve outcomes.

Safety issues with an inter-hospital transport of a patient with a Berlin Heart Excor biventircular assist device

BACKGROUND

Interhospital transfers of pediatric patients on the Berlin Heart Excor have been published on an occasional basis.

METHODS

Nowadays medicine evolves away from just feasibility towards quality and safety issues. Management tools like risk analysis have found their way into clinical practice.

RESULTS

Exemplary, we present a case of a 20 months old boy on a Berlin Heart BiVAD Excor who underwent a 224 km ground transport. After a systematic review of the published literature, we describe our safety management with the aim was to provide highest quality of care for the transport.

CONCLUSION

Besides a risk analysis, we also describe our training and simulation protocol.
