The 70cc Total Artificial Heart (TAH) has been utilized as bridge to transplant (BTT) for biventricular failure. However the utilization of 70cc TAH has been limited to large patients for the low output from the pulmonary as well as systemic vein compression after chest closure. Therefore the 50cc TAH was developed by SynCardia (Tucson, AZ, USA) to accommodate smaller chest cavity. We report the first TAH exchange from a 70cc to 50cc due to a fit difficulty. The patient failed to be closed with a 70cc TAH, although the patient met the conventional 70cc TAH fit criteria. We successfully closed the chest with a 50cc TAH.
