Figure 4.
Left ventricular chamber compliance plotted as a function of normalized left ventricular end-diastolic interstitial fluid pressure. The normalized value was calculated as the recorded myocardial left ventricular interstitial fluid pressure at end-diastole minus left ventricular end-diastolic chamber pressure. We placed boundary limits on the lower values of myocardial extravascular fluid to avoid negative or non-physiological values (*) of left ventricular chamber compliance.45 (Desai et al.,45 used with permission.)
