Pressure-Volume Loop Catheterization

Pressure-volume loop catheterization enables us to do a complete assessment of cardiac function. Pressure-volume loops (PV loops) are generated by recording both the pressure and volume simultaneously and allows us to assess systolic and diastolic cardiac function.

Figure 3. Left-ventricular end-systolic and end-diastolic pressure-volume relationship of a TAC animal model.

Figure 4. The left pressure-volume loop shows the end-systolic pressure-volume relationship of the right ventricle of a SHAM mouse. The right pressure-volume loop shows the end-systolic pressure-volume relationship of the right ventricle of a mouse that underwent pulmonary artery banding (PAB) surgery.
