Invited commentary

The authors of this report are to be commended for demonstrating the feasibility of obtaining load-independant estimates of right ventricular (RV) performance at various levels of inotropy (families of pressure–volume loops) with bedside technology. In this study, RV pressures were transduced using a high-fidelity, low-compliance transduction system. This pressure measurement technique simply represents the standard method for accurately measuring rapidly occurring changes in intracavity pressure. The originality of the paper lies in the application of clinically available, nonradionuclear technology to the estimation of the . . . [Full Text of this Article]
