| Abstract: | The right ventricular ejection fractions derived from two dimensional echocardiograms and cineangiograms were compared in 24 children. All patients (aged 2.1 to 16 years) had undergone Mustard repair for transposition of the great arteries 1 to 12 years earlier. The correlation of the two methods was excellent (r = 0.977), confirming the usefulness of echocardlography for deriving ejection fraction. The volume components of the ejection fraction were less well estimated from the echocardiograms, but the ratios of end-diastolic to end-systolic volumes estimated from each method were similar. |
