Abstract
Colour Doppler flow mapping (CD) has proved to be a very sensitive and specific means of diagnosing valvular regurgitation and obtaining a rapid semiquantitative estimation of the severity of regurgitation itself. We tried to compare a semiquantitative evaluation of aortic and mitral regurgitation, without time-consuming calculations of regurgitant jet areas, with the conventional visual semiquantitative angiographic estimation. We have also evaluated in detail the interobserver variability of this type of semiquantitation.
Two independent observers (OB) have reviewed CD studies of a selected group of 47 consecutive patients who underwent both cineventriculography and aortography for aortic regurgitalion (AR) and/or mitral regurgitation (MR), then graded as mild, moderate or severe. AtCD, AR and MR were classified as present or absent and graded as mild, moderate or severe. The following interobserver percentage agreements were noted for AR presence or absence, AR grade, MR presence or absence, MR grade, respectively: 96%, 83%, 96%, 83%. Likewise, the respective echo-angio agreements were 90%, 58%, 80%, 70%. Agreement was significant (P<0.001) in all cases.
Thus, good interobserver and echo-angio agreement was found in the CD assessment of AR and MR. However, under- or over estimation of CD vs. angio was noted in several cases (mostly by one grade). Underestimation of CD vs. angio was 27% for AR and 18.5% for MR; overestimation of CD vs. angio was 15% for AR and 11.5% for MR.
CD has proved to be a useful technique not only for the qualitative but also for the semiquantitative evaluation of aortic and mitral regurgitation, as assessed in the same subjects, with good interobserver agreement. The disagreement between CD and angio has been generally by one grade of severity and is probably due mainly to the different type of information given by the two techniques.
