Fra？？o de eje？？o e volumes do ventrículo esquerdo medidos com eco 3D e com tomografia ultra-rápida

background: real-time three-dimensional echocargiography (rt-3d-echo) and ultrafast computed tomography (ct) are two novel methods for the analysis of lv ejection fraction and volumes. objective: to compare lvef and volume measurements as obtained using rt-3d-echo and ultrafast ct. methods: thirty nine consecutive patients (27 men, mean age of 57±12 years) were studied using rt-3d-echo and 64-slice ultrafast ct. lvef and lv volumes were analyzed. statistical analysis: coefficient of correlation (r: pearson), bland-altman analysis, linear regression analysis, 95% ci, p<0.05. results: rt-3d-echo measurements: lvef ranged from 56.1 to 78.6 (65.5±5.58)%; end-diastolic volume ranged from 49.6 to 178.2 (87±27.8) ml; end-systolic volume ranged from 11.4 to 78 (33.1±13.6) ml. ct scan measurements: lvef ranged from 53 to 86% (67.8±7.78); end-diastolic volume ranged from 51 to 186 (106.5±30.3) ml; end-systolic volume ranged from 7 to 72 (35.5±13.4)ml. correlations between rt-3d-echo and ct were: lvef (r: 0.7888, p<0.0001, 95% ci 0.6301 to 0.8843); end-diastolic volume (r: 0.7695, p<0.0001, 95% ci 0.5995 to 0.8730); end-systolic volume (r: 0.8119, p<0.0001, 95% ci 0.6673 to 0.8975). conclusion: good correlation between lvef and ventricular volume parameters as measured by rt-3d-echo and 64-slice ultrafast ct was found in the present case series.
