  • Failure to wean from ECMO
  • Massive myocardial infarction or direct myocardial injury that affects technical insertion of a VAD

Fit assessment

The most useful determinant of whether the 70cc or 50cc SynCardia TAH will fit in a patient’s chest is the T10 measurement. Commonly assessed via CT scan, the T10 measurement is the anteroposterior distance between the sternum and the 10 thoracic vertebra (T10). Patients with a T10 measurement ≥ 10 cm should be considered for the 70cc SynCardia TAH.

Example A

T10: 13.7 cm

Example B

T10: 8.3 cm

Bridge To Transplant


  • At risk of imminent death from biventricular heart failure
