Doppler color flow mapping offers the potential to assess serial changes in mitral regurgitation associated with therapeutic interventions such as surgical valve repair or afterload reduction. However, the day to day variability of color flow jets in mitral regurgitation must be established to distinguish therapeutic responses from random variation. Therefore, 14 patients with mitral regurgitation were each studied on 5 sequential days by color flow velocity mapping. Instrument settings were kept constant for each patient, and no patient had a significant change in heart rate, blood pressure, left ventricular end-diastolic dimension or circumferential wall stress between studies. To assess day to day variability, the area of the Doppler color flow map was carefully measured in multiple views by an experienced echocardiographer. |
