ventricular filling pressure

ven·tric·u·lar fill·ing pres·sure

the pressure in the ventricle as it fills with blood, ordinarily equivalent to the mean atrial pressure when there is no AV valvular gradient. Atrial pressure can be used in place of transmural pressure because pericardial pressure usually varies between -2 and +2 mm Hg and hence is negligible. During cardiac tamponade, pericardial and atrial pressures equilibrate so that transmural pressure is zero and the high atrial presures cannot be "filling" pressures.

Concentrations of natriuretic peptides, and to a lesser extent of troponins, correlate with left ventricular thickness, symptom status, and left ventricular hemodynamics by Doppler measurements (left ventricular filling pressure, left ventricular outflow tract gradient).

In the present study, DT was increased after esmolol was administered, which suggested that myocardial compliance of the left ventricle was improved.[sup][18] When analyzing changes in myocardial compliance from the aspect of the pressure–volume relationship at the left ventricular end-diastolic pressure, E/Ea is generally considered to be related to the left ventricular filling pressure. An increase in the left ventricular filling pressure decreases Ea velocity and increases E-wave velocity, thus increasing the E/Ea ratio.[sup][19] However, no significant change in the E/Ea ratio was found in the present study after administering esmolol compared with before treatment.

In patients admitted to the emergency department, CVP should be monitored in cases of shock, circulatory failure, massive infusion or transfusion requirement, situations with massive bleeding risk, situations where careful fluid resuscitation is a must such as in pediatric patients or patients with cardiac problems.3 CVP is a value indicating right atrial pressure or right ventricular filling pressure. In its simplest terms, CVP is an indicator of intravascular fluid status and right heart function.
As diastolic dysfunction progresses and the patients exhibit a pseudonormal (second degree) or restrictive (third degree) mitral flow, the passive conduit function increases, while the reservoir and active pump functions decrease significantly; in fact most of ventricular filling occurs during early diastole and not during late diastole because of the increased left ventricular filling pressure and because of the decreased force of contraction.
