Does radionuclide measurement of regional left ventricular ejection fraction reliably assess regional left ventricular performance compared to contrast angiography?

Population

43 patients assessed by both gated equilibrium radionuclide angiocardiography and left ventricular contrast angiography, including 10 with normal contrast ventriculograms and without obstructive coronary artery disease, and 33 evaluated prospectively.

Intervention

Radionuclide measurements of regional left ventricular ejection fraction (gated equilibrium radionuclide angiocardiography)

Comparator

Left ventricular contrast angiography

Outcome

Agreement in the presence or absence of abnormal wall motion between radionuclide and roentgenographic methods, and comparison of regional ejection fraction across normokinetic, hypokinetic, and akinetic segmentssurrogate

Radionuclide regional ejection fraction provides a reliable quantitative assessment of regional left ventricular performance that correlates well with contrast angiography.
