In 34 patients, we assessed the reproducibility and accuracy of a new, computerized, thermodilution method that determines right ventricular ejection fraction (RVEF). We compared the results from this new algorithm with simultaneous results from the conventional plateau thermodilution method and from both first-pass and gated nuclear techniques. Using this new method improved the reproducibility of thermal determinations of RVEF. Although the thermal values were lower, the correlations between thermal and nuclear measurements were close [r = .92 (first-pass technique), r = .81 (gated technique)]. This new method seems particularly appropriate for serial monitoring of RV performance.
