Why the study?
Does two-dimensional echocardiography accurately estimate left ventricular volumes and ejection fraction compared to biplane cineangiocardiography in children with congenital heart disease?
Population
25 children with congenital heart disease
Comparison
Two-dimensional echocardiography using 8… vs Biplane cineangiocardiograms (reference standard)

May aid noninvasive LVEF assessment in pediatric CHD; supports validation studies but leaves open prospective confirmation.
Does two-dimensional echocardiography accurately estimate left ventricular volumes and ejection fraction compared to biplane cineangiocardiography in children with congenital heart disease?
Two-dimensional echocardiography, particularly using the ellipsoid biplane formula, provides accurate estimates of left ventricular volumes and ejection fraction in children with congenital heart disease.
Mercier et al. (1982) studied this question.
