In fact, among the evaluations of LV volume, mass, and function by CMR, LVM appears to be the least reproducible and most variable parameter (44). This is because LVM is derived from the difference of 2 volumes (total LV volume and end-diastolic volume). Although gradually less significant...
LV mass was then indexed for body surface area to generate the LV mass index (LVMI). Peak early-diastolic (E) and peak late-diastolic (A) transmitral velocities, the E/A ratio, and the deceleration time of the E wave were measured from the apical four-chamber view by pulsed Doppler ...
As a 3D metric, the mass/volume ratio has obvious advantages over any 1D measurement and accordingly is used to more definitively relate changes in LV geometry over time. The mass/volume ratio demonstrated no change initially (1.9 to 2.0 at 6 months) remaining unchanged at 1 year (2.0) and...
(LVID)3] + 0.6, where IVSd is the diastolic interventricular septal diameter, LVDd is the diastolic LV dimension, and PWd is the diastolic posterior wall diameter. LVMI was calculated as LV mass divided by body surface area [19]. The mean inter-observer difference of LVMI was 6.6...
LV global volume was defined as the sum of LV mean cavity volume ([LV end diastolic volume + LV end systolic volume]/2) and myocardial volume (LV mass/myocardial density of 1.05 g/ml)3. No patient was in atrial fibrillation at imaging. Follow-up ranged between initial office visit to ...
The multi-slice LV cine datasets were analyzed to calculate end diastolic volume, end systolic volume, end diastolic myocardial mass, ejection fraction and mass to volume ratio.NikitinAcademicN.AcademicP.AcademicSilvaAcademicR.AcademicDeAcademic

In some embodiments, a method of ameliorating diastolic dysfunction may include positioning at least a distal end of a system for cutting a trabeculae carneae in a left ventricle of
