The left ventricular posterior wall thickness
(LVPT), left ventricular lumen diameter (LVLD), interventricular septum thickness (IVST), right ventricular wall thickness (RVT), cut surface cranio-caudal diameter (CCD), cut surface latero-lateral diameter (LLD), cut surface area (CSA), left ventricular area (LVA) and right ventricular area (RVA) were measured according to Kershaw et al.
The cardiac function of all mice including left ventricular end-diastolic diameter (LVID d), left ventricular end-systolic diameter (LVID s), left ventricular end-diastolic volume (LV Vol d), left ventricular end-systolic volume (LV Vol s), left ventricular end-diastolic posterior wall thickness
(LVPW d), left ventricular end-systolic posterior wall thickness
(LVPW s), left ventricular end-diastolic anterior wall thickness (LVAW d), left ventricular end-systolic anterior wall thickness (LVAW s), ejection fraction (EF), fractional shortening (FS), and stroke volume (SV) was assessed on days 0, 7, 14, 28, and 56.
Echocardiogram parameters indicates the significant difference (pless than 0.002) in Left Atrial and Aortic ratio (LA/AO), Interventricular septum thickness (Pless than 0.03), Left ventricular posterior wall thickness
(pless than 0.05), diastole PDA gradient (pless than 0.005) between HsPDA and non-HsPDA.
All cases were examined by iE33 Echocardiography system to detect left ventricular end-diastolic dimension (LVEDD), left atrial diameter (LAD), left ventricular posterior wall thickness
in diastole (LVPWT), interventricular septum thickness in diastole (IVST), and left ventricular ejection fraction (LVEF).
There was no difference between the groups regarding left ventricular end-diastolic dimension, left ventricular end-systolic dimension, interventricular septum thickness in diastole, interventricular septum thickness in systole, left ventricular posterior wall thickness
in diastole, left ventricular posterior wall thickness
in systole, left atrium dimension, aortic dimension, ejection fraction, and fractional shortening.
These include left ventricular mass (LVM, gm), left ventricular internal diameter end-diastolic (LVIDd, cm), left ventricular internal diameter end-systolic (LVIDs, cm), septal wall thickness (SWT, cm), posterior wall thickness
Age, weight, height and Body Mass Index were demographic variables while left ventricular end-diastolic internal diameter, diastolic interventricular septal thicknesses, left ventricular posterior wall thickness
, and left ventricular mass were research variables.
The posterior wall thickness
is greatest inferiorly, at 6.5 [+ or -] 2.5 mm, when measured immediately superior to the coronary sinus and between 6 and 15 mm from the mitral annulus.
In Figure 12, the posterior wall thickness
variations are presented and the related sixth harmonic values are also graphed.
Interventricular septal thickness (IVS) and posterior wall thickness
(PW) in diastole and systole and right ventricular diameter (RVD) were measured.
The septal wall thickness, posterior wall thickness
, left ventricular diastolic and systolic dimensions and septal-to-posterior wall ratio was checked.
Left ventricular end-diastolic dimension (LVEDD), left ventricular end-systolic dimension (LVESD) interventricular septum (IVS) and LV posterior wall thickness
(LVPW) dimensions in diastole, aorta and pulmonary artery dimensions, right ventricular dimension were measured by standard M-mode guided by two-dimensional echocardiogra-phy.
