Comparison of techniques for the measurement of left ventricular function following cardiac transplantation.

Background: Assessment of graft function after cardiac transplantation is essential for patient management and clinical research. Previous studies have found that the left ventricular (LV) ejection fraction (EF) by echocardiography (echo), radionuclide ventriculography (RNV), and cardiovascular magnetic resonance (CMR) is discrepant in patients with heart failure.

Method: Twelve patients underwent LV EF assessment by echo, angiography (angio), RNV, and CMR one year following heart transplantation.
