Implication

Supports feasibility for intraoperative view simulation in congenital heart defects; leaves open impact on surgical planning or outcomes.

Key Points

To evaluate the feasibility, data acquisition methods, and clinical potential of dynamic three-dimensional echocardiography for diagnosing congenital heart defects.
Assessed 238 pediatric patients aged 3 days to 19 years (mean 4.3 years), including 13 individuals with normal hearts and 225 with congenital heart defects.
Acquired 80 to 120 cardiac slices using computer-controlled parallel, rotational, or fan-like transducer scanning synchronized with electrocardiographic and respiratory gating.
Dynamic 3D dataset reconstruction enabled slicing along arbitrary planes to generate realistic perspectives simulating intraoperative views.
The technique successfully visualized internal morphology, including ventricular septal defects and atrioventricular valves via atrial views, muscular defects via ventriculotomy, and left ventricular outflow tract obstructions via aortotomy.

Does three-dimensional echocardiography facilitate the visualization and surgical planning of congenital heart defects in pediatric and young adult patients?

Population

238 patients aged 3 days to 19 years with normal hearts or congenital heart defects evaluated using 3D echocardiography.

Exposure

Three-dimensional (3D) echocardiography using three different modalities of data acquisition (parallel scanning, rotational scanning, and fan-like scanning) with electrocardiographic and respiratory gating.

Outcome

Generation of views simulating intraoperative perspectives for the assessment of congenital heart defects.surrogate

Dynamic 3D echocardiography is a feasible imaging modality that can simulate intraoperative perspectives, demonstrating significant potential to facilitate the planning of intracardiac surgery for congenital heart defects.

Vogel et al. (1995) conducted an observational in Congenital heart defects (n=238). Dynamic three-dimensional echocardiography was evaluated. Dynamic three-dimensional echocardiography generated 80 to 120 slices per dataset, permitting views simulating intraoperative perspectives in 238 patients with congenital heart defects.
