TL;DR: PRFR is determined by both the left atrial pressure and the left ventricular relaxation rate and should be used with caution as an index ofleft ventricular diastolic function.

TL;DR: In this paper, the authors proposed a logarithmic approach to quantify the passive properties of the intact ventricle and the effects of elastic recoil by separating filling from relaxation with a method of volume clamping with a remote-controlled mitral valve.

TL;DR: The validity of transesophageal echocardiography is confirmed and its usefulness in monitoring changes in ventricular function during cardiac surgery is confirmed.

TL;DR: Left ventricular relaxation in the filling and transiently nonfilling working hearts of seven open-chest pentobarbital-anesthetized dogs is studied by totally occluding the mitral annulus during one systole to evaluate the validity of a monoexponential characterization of relaxation.

TL;DR: The findings underscore the need for clinicians and investigators studying neuropsychological dysfunction following cardiac operations to take concurrent emotional and physical states into account, and to make repeated measures well separated in time, before interpreting the presence or absence of residual Neuropsychological problems.
