As clinical interest in right heart dysfunction and its effect on overall cardiovascular health has increased, a growing number of researchers are studying right ventricle (RV) pressure volume (PV) loops with the Millar MPVS Ultra system in both small and large animals. Because RV PV is a relatively new area of research, there are a limited number of publications currently available (see the links to selected citations listed below).
- McKay - Instantaneous measurement of LV and RV stroke volume and PV relationships with an impedance catheter.pdf
- Pressure Overload Induced RV dysfunctionEHJ2007.pdf
In order to account for the differences in RV loops compared to left ventricle (LV) loops, ADInstruments introduced two new algorithms into the PV Loop Module 2.5 . These new algorithms provide improved, automatic detection of end-systole for both right and left ventricular PV loops as well as in situations where LV PV loops may take on a more 'triangular' shape. A video explaining the changes can be found HERE .
