Heart is the most important part of the
body and the key of blood circulation. It is located beneath the sternum and is
about the size of our fist. The heart beats average seventy beats per minute
and pumps about 5 liters of blood per minute, or total volume of blood in the human
body each minute.
Humans are not able to live without hearts
and many scientists have been focusing on how to mend a broken heart.
There are four heart replacement
technologies that are most well-known to modern science: Human Heart Donation,
Xenotransplantation, Tissue Engineering, and Artificial Heart. Each method has
saved many lives who suffered or could die from the malfunction heart.
To begin with, I would like to discuss
about ‘Human Heart Donation’. This method, as the name suggests, is replacing
the malfunction heart with donor’s heart which is donated from charity or possibly
individual volunteers. Donation is the key to patients who desperately are
waiting for the heart plantation as severity of their hearts are critical. As
such, the situations can be when other treatments for errors in the heart have
not worked, leading to heart failure in the future. When the operation of heart
transportation is done, you will be able to recover after the operation in just
a few weeks although you will be weak at the start. It is also very important
to have simple activities to strengthen your health; “pushing, pulling or heavy
lifting until your breastbone is fully healed.” (Bhf.org.uk, 2018)
Second heart replacement technology is ‘Xenotransplantation’.
As the prefix, ‘Xeno-‘ means alien, strange and guest, this technology, unlike
from ‘Human Heart Donation’, is “any procedure that involves the
transplantation, implantation or infusion into a human recipient of either live
cells, tissues, or organs from a nonhuman animal source.” (Fda.gov, 2018) This
technology was developed by the fact that the need for the human organs far
exceeds the current supply.
