For these purposes the transpulmonary thermodilution technique allows assessment of preload cardiac output filling volumes and metrics of contractility without the need to pass a catheter through the right heart. In a previous issue of Critical Care Ritter and colleagues compare metrics of transpulmonary thermodilution with the PAC in patients with acute heart failure and severe sepsis. The results add to a growing body of evidence that the PAC adds little to information attainable by less invasive methods in many conditions including acute heart failure. Whether newer devices improve outcome needs to be tested in well-controlled prospective trials. In a previous issue of Critical Care a comparison was made between metrics of transpulmonary thermodilution TPT and the pulmonary artery catheter PAC in patients with acute heart failure AHF and sepsis 1 . The results showed acceptable correlation between metrics derived from the two techniques and showed that TPT allowed identification of heart dysfunction in both heart failure and sepsis. This study while small and retrospective adds to mounting evidence that routine use of the PAC is
