title: Persistent Left Superior Vena Cava Demonstrated by First-Pass Radionuclide Angiography.
abstract: Persistent left superior vena cava (PLSVC) is a development variation of the embryonic thoracic venous system. It can be isolated or associated with congenital heart disease combined with shunting problems. Many image findings of PLSVC have been reported, but few mentioned findings in a first-pass radionuclide angiography. We report a case of PLSVC found incidentally in a first-pass radionuclide angiography with tracer injection through the left jugular vein. The right ventricular ejection fraction was underestimated. Injection via the right jugular or right cubital vein is recommended to obtain accurate ejection fractions in cases of PLSVC without shunting.
