Atrioventricular Fistula

Atrioventricular fistula (pronunciation: A-tree-o-ven-TRIK-yoo-lar FIST-yoo-la) is a medical condition characterized by an abnormal connection between an atrium (the upper chamber of the heart) and a ventricle (the lower chamber of the heart).

Etymology

The term "Atrioventricular fistula" is derived from the Latin words 'atrium' and 'ventriculus' which refer to the chambers of the heart, and the Latin word 'fistula' which means pipe or tube.
