O2 over ice: Oxygen-powered ‘heart-in-a-box’ keeps donor organ alive for 9 hrs | Unlike standard cold storage, the heart-in-a-box provides continuous oxygenation and nutrient supply to the heart.

From the article: A heart transplant is a life-saving procedure, but the transportation of a donated heart to its recipient is often a race against time.

To address this, researchers have developed a cutting-edge technology called a “heart-in-a-box.” This device allows donated hearts to be kept alive and functioning outside the body for longer periods.

The University of Gothenburg study found that using this new device for donor heart preservation can significantly lower the likelihood of early heart failure in transplant recipients compared to typical cold storage methods.

Unlike standard cold storage, the heart-in-a-box provides continuous oxygenation and nutrient supply to the heart, helping to maintain its health and function.

The current standard procedure involves storing donated hearts in ice-filled coolers at 4°C in potassium solution. However, handling donated hearts is a critical time-sensitive process.

To reduce the risk of complications for the recipient, the donor-receiver match, heart transportation, and surgical implantation must all be accomplished within a four-hour window.

This study found that hypothermic oxygenated machine perfusion (HOPE) or a heart-in-a-box device can increase the storage period of donated hearts by up to nine hours.

Compared to traditional static cold storage, this innovative technology keeps the heart at eight degrees. In addition, the device includes a pump, tubing, a reservoir, and a circulating fluid to keep the resting heart oxygenated as it awaits transplantation.

Ice, plus oxygen, plus other cool tricks we’ll learn in the future.
