Left Ventricular Filling and Diastolic Pressure-Volume Relations
In 7 conscious dogs, left ventricular diastolic volume (V) was estimated by taking biplane cineradiographs with the left ventricular cavity previously outlined by permanent radiopaque markers. Left ventricular pressure (P) was measured with an implanted miniature transducer. There were two rapid filling periods during early and late diastole; little filling occurred during the middle third of d...
متن کاملSibling resemblance for left ventricular structure, contractility, and diastolic filling.
Although there is evidence that left ventricular (LV) function is genetically controlled, the contribution of familial factors to variation and covariation of LV diastolic filling, contractility, and structure is unknown. Single- and cross-trait sibling correlations were estimated using bivariate familial correlation models in 200 white (400 pairs) and 374 black (539 pairs) hypertensive sibship...
متن کاملHydraulic forces contribute to left ventricular diastolic filling
Myocardial active relaxation and restoring forces are known determinants of left ventricular (LV) diastolic function. We hypothesize the existence of an additional mechanism involved in LV filling, namely, a hydraulic force contributing to the longitudinal motion of the atrioventricular (AV) plane. A prerequisite for the presence of a net hydraulic force during diastole is that the atrial short...
متن کاملDoppler assessment of right ventricular filling in a normal population. Comparison with left ventricular filling dynamics.
To examine whether alterations in right ventricular filling dynamics occur with increasing age and to compare right and left ventricular filling in normal subjects, pulsed Doppler echocardiographic studies were performed at the tricuspid and mitral anuli in 50 normal volunteers (23 males and 27 females) with an age range of 5-66 years. An age-related decrease in peak early filling velocity, inc...
متن کاملVortex Ring Formation in Diastolic Dysfunction: Phase Contrast MRI of Left Ventricular Filling
Introduction The formation of vortices during left ventricular (LV) filling (Fig. 1) has been noted in several investigations using phase contrast (PC) MRI [1,2], but the effect of diastolic dysfunction (DD) on vortex formation has not been investigated. We hypothesize that impaired relaxation (IR) and increased stiffness of the LV wall in DD, will substantially alter the kinetics of the vortic...
