Overriding aorta
Overriding Aorta
Overriding aorta (pronunciation: oh-ver-rye-ding a-or-ta) is a medical term used to describe a condition where the aorta is positioned directly over the ventricular septal defect (VSD) in the heart, instead of its normal position over the left ventricle. This condition is often associated with congenital heart diseases, particularly Tetralogy of Fallot.
Etymology
The term 'overriding aorta' is derived from the English words 'over', meaning above or higher than, and 'riding', which in this context means positioned on. The term 'aorta' is derived from the Ancient Greek word 'ἀορτή' (aortē), which means 'that which is hung up' or 'the great artery'.
