Application value of real-time three-dimensional echocardiography in diagnosis of structural heart disease / 军事医学

ABSTRACT

Objective To explore the application value of real-time three-dimensional echocardiography (RT-3DE) in diagnosis of structural heart disease through a comparison with two dimensional echocardiography (2DE).Methods Ninety-two patients with heart disease were enrolled from October 2009 to February 2014 , all of whom were examined by RT-3DE.By cutting and spiraling structural 3D images of lesions in regions of interest , we made a diagnosis of lesions .In addition, the size of atrial(ASD) and ventricular septal defects (VSD),based on surgical results,was measured and analyzed.By comparing the coherence and difference of diagnosis on structural heart disease examined by 2DE and RT-3DE, the accuracy and superiority of RT-3DE were evaluated.Results (1)The 3D images of 92 patients with heart disease were successfully obtained by RT-3DE.The structure of lesions was displayed directly from various angles .In addition, the position, scope and degree of lesions and the spatial relationship of adjacent structures were accurately confirmed.RT-3DE provided more direct, accurate and abundant information than 2DE.(2)In the diagnosis of congenital heart disease, the diagnostic accordance rate of RT-3DE was the same as that of 2DE, but was slightly higher in the diagnosis of valvular disease and other lesions .( 3 ) Compared with 2DE, the ASD maximum diameters obtained from RT-3DE were more correlaed with surgical findings (r=0.94,0.86),so were the VSD maximum diameters (r=0.93, 0.84).Conclusion RT-3DE is easy to operate and quick to produce image ,which can provide more spatial information than 2DE in structural heart disease diagnosis , increase the accuracy rate of diagnosis , and serve as a supplement to 2DE.
