Approximately how long did Haskell Karp survive using the initial artificial heart implant?

Answer

64 hours

Following the implantation of the total artificial heart into Haskell Karp in 1969, the patient survived for approximately 64 hours while utilizing the mechanical device. This duration was critically important because it provided the necessary window of time for a suitable donor heart to become available for the subsequent transplant operation. The successful maintenance of life support for this period, even temporarily, was a significant achievement that validated the device's ability to manage complex circulatory demands in an acute setting.
