Question: how is mitral valve regurgitation measured?
Answer: Regurgitant volume can be calculated by the formula: regurgitant SV = total SV-forward SV, where total SV is the total amount of ejected blood by the LV, measured from left ventricular angiogram, and forward SV the amount of blood ejected through the aortic valve, and measured by Fick's thermodilution technique [6].
