PrMV, Prosthetic mitral valve.
*These indices are used when further information is needed about valve function. EOA is calculated using the continuity equation.
**Often needs transesophageal echocardiographic evaluation because of acoustic shadowing.
***May be difficult in the presence of shadowing or reverberation from the valve.
