Abstract

Aims

The Berlin Heart EXCOR® Adult biventricular assist device (BiVAD) is an approved mechanical circulatory support for patients with end-stage biventricular heart failure. In this prospective post-market clinical follow-up study, we present the first clinical experience of the new EXCOR® Adult pump with bileaflet (BL) valves in Europe.

Methods and results

After CE-mark approval in August 2014, a total of 12 patients were enrolled with a mean age of 44 years ± 11 (range 21–58 years). The majority of patients (n = 11) were in INTERMACS level 1 or 2. Eight patients had a median pre-operative extracorporeal life support (ECLS) of 6 days (range 1–37 days). Primary end point was survival, either to heart transplantation (HTx), recovery or alive at 12 months on device, whichever occurred first. Secondary end point was the number of adverse events throughout EXCOR® BiVAD support. Median support time up to last follow-up on EXCOR® BiVAD device was 248 days (range 57–381 days) and patient survival at 1 year was 92%. Half of the EXCOR® BiVAD patients (n = 6) were transplanted and five patients were still on support at 1 year post-implantation. Complications during EXCOR® BiVAD support were thoracic bleeding, exit site infection and ischemic cerebrovascular incidents in three cases, respectively.

Conclusion

The new EXCOR® Adult pump with BL provides pulsatile high cardiac output with excellent outcome and successful bridging to HTx, particularly in critically ill patients with INTERMACS level 1 or 2 at the time of implantation.

Notes

Acknowledgements

We thank all other VAD coordinators as well as health-care providers involved at each participating center for the professional and cooperative work.

Funding

This work was part of an investigator-initiated post-market clinical follow-up study and was supported by a grant of Berlin Heart GmbH, Berlin, Germany. All centers were equally supported financially by the investigator company Berlin Heart GmbH to refund the efforts of patient inclusion and the preparation of all case individual reports required as per study protocol. All contracted financial support has been reviewed and approved by each individual local ethics committee.

Compliance with Ethical Standards

Conflict of interest

AR and BS received travel grant (for international conferences) from BH and consultancy fees from BH. MJW received speaker honoraria and travel grants from BH. AKM and NJ are employees of Berlin Heart GmbH.
