额断面超声切面法显示左心室局部前壁心肌的实验研究
Visualization of anterior wall of left ventricle using coronal section by two-dimensional echocardiography in a porcine experiment
摘要
Abstract
Objective To evaluate the feasibility and accuracy of visualization for anterior wall (AW) of left ventricle (LV) with coronal section by two-dimensional echocardiography (TDE) in a porcine experiment. Methods Echocardiographic images of AW of LV using coronal section by TDE were compared with those in anatomy in 5 porcine. After collection of images of the AW in TDE, heart was removed and dissected along the path of ultrasonic beam. The images recorded by TDE were compared with those of anatomic views. Displacement, velocity, strain and strain rate in 5 spots at AW of LV by speckle-tracking imaging were analyzed. Results TDE was used to catch the image of myocardium in AW of LV. The images by TDE were in accordance with those seen in anatomic views. Strain and strain rate calculated by soft-ware of Speckle-tracking imaging (STI) were - 1.71%-1.33% and -3.08 s-1-2.49 s-1, respectively. No significant differences were found among the 5 spots in AW of LV (P > 0. 05). Conclusion Two-dimensional echocardiography with coronal section and speckle-tracking imaging may provide a new measure for assessment of regional wall motion of left ventricle.关键词
