Vena contracta is defined as the narrowest part of the jet, just distal to the regurgitant orifice. Vena contracta dimensions reflect the severity of regurgitation.

Vena contracta is the point in a fluid stream where the diameter of the stream is the least, and the fluid velocity is at its maximum, such as in the case of a stream issuing out of a nozzle. It is a place where the cross section area is minimal. Wikipedia
