“…Recently, specific volume parameters like the right ventricular ejection fraction have been evaluated while monitoring right ventricular and global cardiac function at the bedside [1,13–15]. Due to the crescent shape and geometry of the right ventricle, correct assessment of its function has been, and still remains, difficult.…”

“…A major limitation of both techniques was that no continuous assessment of right ventricular parameters was possible: all data had to be obtained by intermittent bolus injection or calculation of the right ventricular fractional area change [6,15,20–23]. To overcome this problem, a new modified pulmonary artery catheter which continuously assesses right ventricular parameters has recently been introduced [24].…”

In 25 cardiac surgical patients, right ventricular ejection fraction was continuously measured with a new pulmonary artery catheter and transoesophageal echocardiography, scanning the 'fractional area change' in a standardised transatrial cross section area. Measurements were recorded at three predefined time points (pre-, intra-, and postoperatively). Both methods were compared using the Bland-Altman analysis. Comparing right ventricular ejection fraction values obtained from the pulmonary artery catheter with those assessed by transoesophageal echocardiography, bias was -3.7%, with a precision of 30.9%. Bias and precision significantly improved when the heart rate was less than 100 beats.min(-1), pulmonary artery pressures were low and cardiac performance adequate. In conclusion, the new continuous pulmonary artery catheter system appears to be a valid and useful bedside monitoring device in the haemodynamic management of critically ill patients.
