This study was designed to test the applicability and the reproducibility of the thermodilution method in the measurement of right ventricular ejection fraction (EF), end-diastolic volume (EDV) and end-systolic volume (ESV) in unsedated cattle. In the 16 healthy calves studied, it was possible, using a fast response thermodilution catheter, to obtain characteristic exponential steplike washout curves, allowing the calculation of right ventricular EF, EDV and ESV. Five to 10 successive thermodilution curves were recorded within a few minutes and two to five similar sets of measurements were performed throughout the same day to test the reproducibility of the technique. The same protocol was repeated the following day. Right ventricular EF, EDV and ESV were reproducible successively, throughout a given day and on following days. The mean intraset, intraday and interdays coefficients of variation ranged from a mean of 4.0 (SD 4.1) per cent to a mean of 18.2 (SD 7.9) per cent. Values of right ventricular volumes and EF agreed with those previously reported in various animal species. Thermodilution was, therefore, shown to be a useful method for measuring with a satisfactory reproducibility, right ventricular EF, EDV and ESV in the unsedated healthy calf.
