Aim: Evaluation of anatomical structure is important for management of the patients with congenital heart disease (CHD). It was usually required for an accurate measurement by 2-dimentional echocardiography (2DE). Recently, transthoracic 3-dimentional echocardiography (3DE) is useful for understanding anatomical structure before surgical operation. We assessed anatomical structure in patients with congenital heart disease using real time 3DE. We provide the clinical utility of Left ventricular (LV) volume measurement using 3D data set. Method: We performed transthoracic 3DE on 10 patients (2months to 5years old) with CHD include in complex CHD.
Transthoracic 3DE was performed using a Philips iE33 system with an X7-2 probe. The 3DE images were acquired full-volume 3DE data sets and reconstructed using an offline computer system (QLAB Ver.5.0, Philips Medical Systems Inc. Andover, MA, USA). Result: There were 10 patients with CHD include ventricular septal defect(VSD), patent ductus arteriosus(PDA), Ebstein’s anomaly, complete transposition of the great arteries(TGA), double outlet right ventricle(DORV), tetralogy of Fallot(TOF), coarctation of aorta complex, congenital mitral valve regurgitation, pulmonary atresia with VSD and supra mitral ring. 3DE described accurate images of various CHD. Valve disease and shunt were diagnosed by 3DE, which could not be diagnosed by 2DE. The LV volume was determined by 3DE tend to be correlation those measured by cine angiography (r=0.88).
PDA, CoA and shunt were provided an accurate description as well as 3D computed tomography. Conclusion: 3DE is useful of understanding the morphology and physiology of the CHD. 3DE is a valuable noninvasive method in clinical setting
