Heart transplant performed using procedure that could drastically expand donor pool

Doctors bring dead heart ‘back to life’ — in first of its kind surgery in the US

Warm perfusion is a process by which a heart from a recently deceased individual is flushed with warm, oxygen-rich blood, giving it a new lease on life and preserving it for transplant for several hours after it would typically have expired.

A human heart was transplanted for the first time ever in 1967 in South Africa. A 12 months later, Stanford College docs carried out the primary such transplant within the US. "DCD transplantation is done regularly in the US for organs other than the heart, although DCD heart transplants have been conducted in Europe and Australia". The registered donors don't seem to increase in number as well.

The pool shrinks additional after they move away.

Many organs are too damaged or in poor conditions that render them unusable.

Still others may be cast aside based on their donors' medical histories, lifestyles or infections they've contracted.

Schroder says the DCD heart procedure has the potential to expand the donor pool by up to 30%. "This is the donor pool actively expanding!", he posted on Twitter.

Along with assembly well being standards, time performs a big function within the viability of organs.

Normally, tissue that makes up the heart starts to die shortly after it stops beating, making it unusable.

According to Daily Mail, the surgery - believed to be first of its kind in the USA - was part of ongoing experiments to end the perennial scarcity of heart donors in cases involving heart transplant.

Historically, the best defence against the heart's decay has been keeping the organ at very cold temperatures.

But if doctors can instead get a heart beating again after removing it from the donor's body, the organ will be "alive" once more, independent of the person who has died.

Heart tissue usually begins to deteriorate even before a patient has been declared dead due to low oxygen levels produced by the slowing heart.

Nurtured once more, the heart muscle is 'reanimated, ' and jumps back into action.

The technique was first used at Royal Papworth Hospital in the United Kingdom in 2015 and has since successfully transplanted about 75 healthy hearts to patients.

It is the first heart transplant to be carried out after a donor's heart has stopped beating, known as donation after cardiac death (DCD), rather than after a person has been diagnosed with brain death (DBD) but their heart is still beating, in the States.

Proof of idea that docs right here can do the process, Dr Schroder hopes, will imply extra hearts shall be viable for extra sufferers.
