Thing 1 - A change of heart (ba-dum-tsh) while it's beating
As if transplanting a heart 🫀 isn't hard enough, Stanford Medicine surgeons did it while it was still beating 🤯
To avoid stopping the donor's heart twice. Wait, what?
Most transplants are done with donors who have been declared brain dead. This means their brain will never work again, but their heart is still going strong.
When surgeons take the heart out, it stops. Doh!
With cardiac death donors, the heart was already stopped for some time. Surgeons need to restart it before implanting it. Huh? It's for various reasons, such as to assess its function and viability.
With brain-dead donors, the heart is stopped once and restarted in the recipient.
With cardiac-dead donors, the hearts end up being stopped twice. Which can damage the heart's tissue and impair its performance after transplantation.
If you can transplant the heart while it's still beating, you can avoid stopping it twice.
- This expands the pool of available hearts - and the recipient list is long...
- It can improve the quality and function of the donated heart
by avoiding the second stoppage
- It can improve the outcomes and survival rates of the recipients
by reducing the risk of complications
We’re looking into ways of never having to stop the heart — that’s the next step.

What did I miss?
Thing 3 - Wisdom from the Court
If you don't have the time to do it right, when will you have time to do it again?
- John Wooden, a legendary basketball player and coach who focused on excellence and character
If you're gonna spend ages on something, shouldn't you squeeze every last drop of long-term goodness juice out of it? 💦
Cause let's face it, you're not gonna jump at the chance to do it all over again.
And if you did, just think of all the sweet benefits we'd be missing out on in the meantime.
