Abstract [en]

Throughout left ventricular systole, with the mitral valve closed, pulmonary venous flow fills the left atrium, presumably stretching and storing potential energy in the left atrial walls. During early diastole, immediately following mitral valve opening, this potential energy is presumably available to assist rapid (E-wave) filling. Later in diastole, ECG P-wave activation triggers left atrial contraction that actively drives additional (A-wave) LV filling. When the mitral valve is open, however, there is nothing to prevent pulmonary venous flow from directly entering the left ventricle, with the left atrium acting only as a conduit. In this chapter we attempt to estimate the relative proportion of left ventricular filling that can be ascribed to the potential energy stored in the left atrial walls and left atrial contraction in relation to left ventricular filling that can be attributed to direct conduit flow.
