Identification of right-side imaging by three-dimensional echocardiography / 中华超声影像学杂志

ABSTRACT

Objective Because a three-dimensional reconstucted imaging resulting from any site or orientation was acquired,the useful and helpful images for diagnosis should be identified.The present study is to identify a series of right-sided three-dimensional echocardicgraphy over transesophageal two-dimensional echocardicgraphy.Methods Three-dimensional echocardiography was performed in 5 normal subjects and 10 patients.With transesophageal echocardiography,the transducer was inserted into esophagus in different depth which can be visualized right atrium,tricuspid valve and right ventricular cavity.In these different depth,ninety rotational(2 degree interval)sector images of the heart were separately collected and digitized with the echo-scan system.After the images were processed,a three-dimensional data set was established.Any desired right-sided three-dimensional echocardiography could be computed,volume rendered and displayed in monitor.Results The images Of right-sided three-dimensional echoeardiography were reconsturcted in all subjects.A series of useful and helpful right-sided three-dimensional echocardiography were identified for diagnosis as following①The image of sagital SVC and IVC.②IAS visualized from right atrium.③TV displayed from right atrium.④IVS rendered frma right ventricle.⑤IVS visualized from fight ventricle.⑥RA,TV,RV and RVOT entire appearance.(Z) RARVOT.PV and PA image.⑧The image of free wall of right ventride.⑨IAS,TV,IVS and RVOT entire appearancL Conclusions Three-dimensional eehocardiography is clinically feasible and useful.The images of richt-sided three-dimensional echocardiography identified with be helpful to diagnose the right-sided heart diseases.
