What are the BIG questions we are trying to answer today? What scientists have contributed to the advancement of heart transplant surgery? What different treatments are available for heart disease patients? BIG SKILL FOCUS – Use of the internet to find out information

Heart Transplants LINK What scientists have contributed to the advancement of heart transplant surgery? Heart Transplants LINK

Pioneers of Heart Transplants… What scientists have contributed to the advancement of heart transplant surgery? Pioneers of Heart Transplants… Christiaan Barnard

Pioneers of Heart Transplants… What scientists have contributed to the advancement of heart transplant surgery? Pioneers of Heart Transplants… Louis Washkansky was the first man to receive a transplanted heart from a car accident victim. He died 18 days later…

What scientists have contributed to the advancement of heart transplant surgery? Christiaan Barnard Experimented with animals, including monkeys and dogs. Performed an experimental procedure on a terminally ill patient. What are the ethical issues surrounding his experiments? Consider the pros and cons of his approach…

Pioneers of Heart Transplants… What scientists have contributed to the advancement of heart transplant surgery? Pioneers of Heart Transplants… Sir Magdi Habib Yacoub OBE. Has performed over 2000 heart transplants in London.

What scientists have contributed to the advancement of heart transplant surgery? Magdi Yacoub Continues to perform heart surgeries and research to this day. What problems would Magdi Yacoub face that would make it difficult for him to do his job?

Immunosuppressants It is essential that donor hearts are tissue typed. What different treatments are available for heart disease patients? Immunosuppressants It is essential that donor hearts are tissue typed. Just like ABO blood, antigens on the surface of tissues and organs must be matched or there will be rejection. Following a transplant, a person may be given immunosuppressant drugs. These weaken the immune system to minimise rejection.

What different treatments are available for heart disease patients? Artificial Hearts can be used to replace faulty hearts or be used between heart replacement surgery… LINK

What different treatments are available for heart disease patients? Organ Care System This is revolutionary system called a ‘living organ transplant’. Allows organs to survive for longer outside the body.

What different treatments are available for heart disease patients? LINK

Pacemaker Attached to a patient if their heart beat is irregular. What different treatments are available for heart disease patients? Pacemaker Attached to a patient if their heart beat is irregular. Sends out electrical impulses to stimulate the heart to beat. Can increase or decrease the heart rate depending on level of activity.

What different treatments are available for heart disease patients? Faulty Valves Heart valves from donor humans, pigs, cows and artificial valves.

What different treatments are available for heart disease patients? Faulty Valves Magdi has been researching the use of stem cells to grow new valves!
