AB  - This study addressed the clinical reproducibility and validity of the 
      thermodilution (TD) measurement of the right ventricular ejection fraction 
      (RVEF). Forty-one patients underwent right heart catheterization, including TD 
      RVEF, within 2 h of gated first pass (GFP) and gated blood pool (GBP) 
      radionuclide ventriculography; 21 had single plane contrast right ventricular 
      angiography (ANGIO) during the same catheterization. Analysis of variance showed 
      no difference among three successive TD RVEF measurements. (table; see text) 
      Stroke volume by RV ANGIO correlated with Fick (n = 10, r = .86) and 
      thermodilution stroke volume (n = 21, r = .88). It is concluded that although the 
      thermodilution method is an accurate way to measure flow, it is not an accurate 
      way to measure right ventricular ejection fraction, and by inference, ventricular 
      volumes. The most likely explanation for this finding is incomplete mixing as in 
      previous studies of indicator methods of measuring left ventricular volumes.
