Continuously assessed right ventricular end-diastolic volume
as a marker of cardiac preload and fluid responsiveness in mechanically ventilated cardiac surgical patients.
We analyzed the correlations between the obtained surface areas and the end-diastolic volumes
normalized by body areas.
It is probable that a moderate increase in the end-diastolic volume
of the left ventricle resulted from an increase in MV and consequently an increase in the amount of the preload and left ventricle filling pressure.
Firstly, the increase in end-diastolic volume
related to the myocardial remodeling enhances LV torsion (34).
By increasing the size of the LVA, from 10% to 50% of the left ventricle, the end-diastolic volume
of the aneurysm (EDVS2) is increased.
Global end-diastolic volume
as an indicator of cardiac preload in patients with septic shock.
(18,20,21) Simplistically, the observed phenomenon is the result of the continuously varying response of the left ventricle to subtle changes in end-diastolic volume
, created through cardiopulmonary interaction.
The cardiac magnetic resonance imaging scan showed reduced RV ejection fraction (EF) of 28% and preserved LVEF of 60% with a LV end-diastolic volume
index of 103 ml/[m.sup.2] (Figures 2(e) and 2(f)).
Dilated cardiomyopathy was defined as the presence of diffuse left ventricular hypokinesia (ejection fraction, < 45 percent) and dilatation (left ventricular end-diastolic volume
index, > 80 mL per square meter).
This process would be analogous to pulmonary capillary damage in emphysema, which may increase RV mass and reduce LV end-diastolic volume
and LV mass (Vonk Noordegraaf et al.
In the case group, the right ventricular (RV) end-diastolic volume
decreased from 81.57 [+ or -] 31.47 ml preprocedure to 62.92 [+ or -] 19.07 ml postprocedure during a median interval of 6 months after closure ( P < 0.001), and the RA volume decreased from 106.93 [+ or -] 54.17 ml preprocedure to 79.07 [+ or -] 40.39 ml postprocedure ( P < 0.001).
The heart functions monitored by the researchers included right ventricular ejection fraction (RVEF), end-systolic volume (volume of blood at the maximum contraction point, ESV), and end-diastolic volume
(volume of blood when at the maximum filling point, EDV), stroke volume and cardiac output.
