reported to the ISHLT Transplant Registry. As such, the
presented data may not mirror the changes in the number of
heart transplants performed worldwide
There Are Not Enough Donor Hearts
Now, cardiac transplantation is epidemiologically

Outcomes
• 90% of patients were transplanted, recovered or had ongoing support at 6 months
• Operative 30‐day survival was 96%
• Survival was superior to that which has been previously reported with LVAD usage

“The patient developed shock. Serious
constraint developed among the five members
of our transplant team. Four were in favor of
proceeding.”
“A forceful beat was restored and supported a
blood pressure of 90-100 mmHg for 90 minutes.
The chimpanzee heart was too small for the
large man…”
“Publicity, outcry, criticism were enormous.”
“I decided to wait until Shumway transplanted a
