A New Method for Noninvasive Quantification of Valvular Regurgitation Based on Conservation of Momentum

Abstract

The noninvasive Doppler assessment of regurgitant volume from jet size is limited by the fundamental inequality of jet volume and regurgitant volume and by the dependence of jet dimensions on driving pressure and instrument settings for a given flow volume. Therefore, this study addresses the hypothesis that an equation could be derived from basic physical… (More)
