- Mitochondrial Abnormalities in Tetralogy of Fallot Tetralogy of Fallot (TF) is a genetic disorder in which heart malformations result in abnormal blood circulation, so oxygen does not reach body cells as it should. With insufficient oxygen to accept electrons at the end of miotchondrial electron transfer chains, too many free radicals form. This damages the mitochondriaand the cells. In 2004, Sarah Kuruvilla studied mitochondria in the heart muscle of TF patients. Some of her results are shown in FIGURE 7.13.
