Tricuspid Annular Motion

摘要: Triscupid annular motion is related to right ventricular systolic function in the same way mitral annulus left function. Tricuspid excursion reflects longitudinal of ventricle, and descent anulus correlates with venous inflow atrium. However, it has not been shown clearly how reproducibly quantify this motion. Therefore we describe a method measure triscuspid using two-dimensional oriented M-mode echocardiography from apical view. We studied group 10 normal subjects (mean age, 28.7 years; range, 25 38 years) 29 patients 57.2 20 84 disease side heart but no evidence involvement heart. In each subject, tricuspid were measured respectively at their lateral, septal or medial, anterior, posterior margin points. The total for was, as follows; 24.9 ± 3.5 mm; 20.1 2.5 21.6 3.8 posterior, 22.3 2.3 mm. Interobserver intraobserver variability was low, coefficient variance different points ranging 6.19% 11.56% between observers 4.10% 7.26% within observer. conclude that possible reproducible use diagnostic tool evaluating
