| Unfortunately the surgery did not solve the problem and his heart function deteriorated significantly, with the left side of the heart suffering from a severe lack of blood flow. | |

| Artificial tissue is normally used used on babies for cardiac repairs, but it can fail and it does not grow with the heart, so as the children grow, they require more operations. | |

| But because the materials are not completely biological, they are unable to grow with him and he needs repeat operations. | |

| Because the materials used to fix the heart can be rejected by the patient's immune system, they can cause scarring in the heart that can lead to other complications, and can gradually break down and fail in just a few months or years. | Because the materials used to fix the heart can be rejected by the patient's immune system, they can cause scarring in the heart that can lead to other complications, and can gradually break down and fail in just a few months or years. |
| A child might therefore have to go through the same heart operation multiple times throughout its childhood - around 200 repeat operations for congenital heart defects are carried out every year in the UK. | |
| Louie hopes the breakthrough means the number of operations he faces will be significantly reduced thanks to the stem cell technology and tissues able to grow with his body. | Louie hopes the breakthrough means the number of operations he faces will be significantly reduced thanks to the stem cell technology and tissues able to grow with his body. |
