The present invention relates to an apparatus (10) for the detection and determination of the magnitude of the regurgitant flow of blood across a heart valve by the use of thermodilution. Two thermodilution curves are measured from different parts of the heart, i.e. upstream and downstream the valve. The presence of valvular regurgitation is indicated by detection (18) of the presence of a temprature decrease upstream the valve. The areas below the thermodilution curves are calculated (20) in the first place, and this area information is used for the calculation (20) of the cardiac output and then the magnitude of the regurgitant flow.
