ANALYSIS OF MITRAL REGURGITATION FROM SLIT ORIFICES BY ULTRASONIC IMAGING |
摘要 |
An ultrasonic diagnostic imaging system is described which quantifies regurgitant flow through a plurality of pinhole leaks or a slit leak of a mitral valve. A plurality of orifice locations of a leaking valve are identified and Doppler values obtained from a flow velocity field proximal each orifice. The Doppler values of each flow velocity field vectorially relating to the orifice location are processed to produce a measure of flow through the orifice. The flow measurements for a plurality of such orifices are summed to produce a quantified measure of regurgitant flow through a plurality of pinhole leaks or along a slit leak.
