The methods proposed so far grade regurgitation based on the geometrical features of the regurgitant jet, such as length, width, and area, or on the color varian

Methods of Measuring Blood Velocity,of the bridge. In this situation, the feedback current or output voltage of the servoamplifier becomes a nonlinear function of the fluid velocity. The metal film should be covered by a thin layer of insulating material, usually quartz, which does not interfere significantly with the heat transfer.

Regurgitation,eatment could be interpreted more meaningfully, if the relaive magnitudes of forward and regurgitant flow through the valve were known. A cuff-type electromagnetic flowmeter gives the best measure of exact regurgitant volume at the time of thoracotomy, but this is impractical clinically.
