The spatial study consisted of the detection of the jet origin with respect to upstream and downstream trajectories in the long-axis view, with further identification of each of the three levels from characteristic single-gated Doppler flow recordings, when desired. For the temporal study, color images were gated in midsystole for aortic, and in early diastole for mitral, stenosis. The final step consisted of imaging the jet cross-sectional area in the short-axis view with planimetry. Measurements were compared with those obtained by the Gorlin formula.<\/jats:p>\n                  <jats:p>The procedure was feasible in 43 of 48 studied cases and the correlation between hemodynamic and color Doppler data was satisfactory for both valvular lesions. The best agreement between both methods was for severe stenoses, where the standard error of estimate was the lowest. For large areas the variance in measurements was wider and the correlation coefficient decreased, but this did not cause errors in recognition.<\/jats:p>\n                  <jats:p>This new method provides a convenient and rapid visualization of stenotic jets and is particularly recommended for assessment of severe stenoses, where accuracy was highest for all clinical conditions.<\/jats:p>","DOI":"10.1177\/000331979004100502","type":"journal-article","created":{"date-parts":[[2007,11,26]],"date-time":"2007-11-26T17:46:29Z","timestamp":1196099189000},"page":"352-364","source":"Crossref","is-referenced-by-count":9,"title":["Quantification of Left-Sided Valvular Stenoses by Color Doppler Imaging of Jets"],"prefix":"10.1177","volume":"41","author":[{"given":"Colette","family":"Veyrat","sequence":"first","affiliation":[{"name":"Charg\u00e9 de Recherches au CNRS"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"D.
