  • Survival was significantly improved through a combination of antihypertensive, antimineralization, and anticoagulation treatments.
  • Measures against infection were crucial for enhancing survival.
  • Technical and constructional improvements in blood pumps contributed to successful experiments.
  • Longest survival achieved was 314 days in experimental calves.

Conclusions:

  • Integrated therapeutic strategies and technical advancements are essential for successful TAH implantation.
  • Addressing pathophysiological complications is key to long-term TAH function and survival.
