Dynamic Three-Dimensional Echocardiographic Reconstruction of Congenital Cardiac Septation Defects

Abstract

Dynamic three-dimensional echocardiographic reconstructions of 27 cardiac septation defects were performed in 19 sedated infants and children. Using a subxiphoid rotational scanning approach, complete visualization of the entire shape and breadth of the defect was attained in 11 of 16 ventricular septal defects and 9 of 11 atrial septal defects. This technique enabled the operator to cut slices from the three-dimensional block of echocardiographic data in order to present septation defects in a region- or lesion-oriented fashion. Poor baseline two-dimensional image quality and certain small septation defects that were readily obscured by nearby structures led to inadequate three-dimensional reconstructions. The application of dynamic three-dimensional echocardiography for assessment of cardiac septation defects uniquely provided (1) the ability to present en face views of atrial and ventricular septal defects; and (2) a means by which intracardiac anatomy can be displayed in a region- and lesion-oriented fashion for interventional and surgical planning purposes.

Three-dimensional echocardiography in congenital heart disease

“…Tantengco et al [ 24 ] showed that 3DE provided unique en face views of atrial and ventricular septal defects. Cheng et al [ 25 ] studied 38 patients with atrial and/or ventricular septal defects using 3DE, and compared their results with 2DE and surgical fi ndings.…”

Three dimensional echocardiography in congenital heart defects

“…[26] Cheng et al , studied 38 patients with atrial and / or ventricular septal defects using 3DE, and compared their results to 2DE and surgical findings. They demonstrated novel 3DE views of both atrial and ventricular septal defects and improved accuracy of quantification of the size of the defect by 3DE compared to 2DE (r = 0.92 vs. r = 0.69).…”
