Abstract

The assessment of the magnitude of aortic regurgitation (AR) is mainly performed at present by cineaortography. Many clinicians prefer this subjective assessment which grades valvular regurgitation qualitatively (Sellers et al. 1964). However, cineangiographic techniques do not provide an accurate assessment of the severity of AR because of their relatively gross estimation of the amount of regurgitant flow. The results of medical or operative treatment 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.
