3D printed heart now real: not available soon
Research and Development have no calms in the field of IT and medical. With both the field joining hands for a better future- a better tomorrow. With 3D printers, you can print a lot of things for daily needs. Either it is a car or a house even key chains and also an artificial hand.
But now the research and development have brought a new innovation in terms 3D printed silicon heart.
Artificial heart beat
A team from the ETH university in Zurich has managed to create a soft silicone heart that pumps in a way similar to its organic counterpart. Silicone material that has proven to be accepted by bodies, can also be 3D printed.
ETH created the heart using an organic heart as a template, adding an extra chamber where the central wall of the heart would usually be that can be filled with air, in order to ‘pump’ the heart.
There are currently blood pumps that exist that can stand in while a patient is waiting for a donor heart to arrive, but the artificial nature of the pumping mechanism means the patient lacks a physiological pulse which: “is assumed to have some consequences for the patient”.
Being able to create a functional artificial heart would be revolutionary. According to ETH: “about 26 million people worldwide suffer from heart failure while there is a shortage of donors of heart.”
This heart is definitely a step in the right direction but is still a long way off being a working model. Under test conditions, the heart was only able to maintain 80 BPM (beats per minute, a slightly elevated average heart rate) for 3,000 pumps. This would mean at present, the heart would only last between half an hour to three-quarters of an hour.
Repetition is one of the greatest demands on the heart, if you factor 80 BPM as an average, by the age of 80 your heart will have performed over 3 billion beats. Creating a pump that has the structural integrity that it can perform this many pumps without needing continuous maintenance is going to be a big hurdle.
