| Transplantation, Heart | The replacement of a healthy heart from a recently deceased donor into the chest of a person whose own heart can no longer function adequately. |
| Transposition | Transposition: There are two forms of transpostion: 1. D or dextrotransposition: In this condition the aorta arises from the right ventricle and the pulmonary artery arises from the left ventricle. Blue blood returns from the body and is pumped directly to the body without going through the lungs. These babies are very blue after birth. 2. L or Levotransposition: Sometimes called "corrected transposition".In this condition the right and left ventricles are inverted or transposed. These babies are usually pink, but often times have other serious heart defects. |
| Tricuspid Atresia | A severe congenital heart defect in which the valve between the upper right chamber, the atrium, and the lower right chamber, the ventricle, failed to form, other associated defects are required for life to persist. These children are cyanotic and require surgery. |
