Defining LV Geometry Sex-specific values of LVH were defined as previously: LV mass/ height 2.7 39 g/m (women) and 48 g/m2.7 (men).13 To identify wall thickening, we used a modified formula to calculate concen-tricity. In considering how the ratio of LV mass to volume would reflect wall thickness, we noted in a simple geometric assumption

Relative Wall Thickness (RWT) Familiarize staff w ith p latforms in lab. LV volumes are calculated from a “full volume” data set (raw data). Perform on an LV focused volume (atria are not imp ortant). o Focus on including the entire LV in the pyramidal dataset and obtaining good endocardial border definition.

age4–7 while LV end-diastolic volume decreases with age.2 Thus, relative wall thickness (RWT) has to increase with age as described by Ganau et al.8 As the LV volume decreases with age,2 while LV internal diameter remains unchanged, LV length must decrease with age.

muscle tip level), LV-PW 5 left ventricular posterior wall thickness at end-diastole. LEFT VENTRICULAR (LV) DIMENSIONS AND FUNC-TION are the most important determinants of prognosis in patients with heart failure (1,2). Medical therapy is directed mainly towards improvement of LV function, e.g., by b-blockers and digitoxin (3–5), or towards ...

Degree and distribution of maximum LV thickness values. General clinical and demographic data for the overall study group are reported in Table 1. The mean value of maximum LV thickness for the overall study group was 23 5mm (range 13 to 42). Figure 1 shows the distribution of the five classes of LV thickness in different age groups at diagnosis.

scarce data regarding reference values of regional wall thickness in healthy volunteers. We sought to investigate differences in age and gender of LV rest and stress regional wall thickness with a state-of-the-art SSFP sequence in a modified AHA 17-segment model and present reference values for myocar-dial rest and stress wall thickness. Methods

Conclusions—Normal values for wall thickness are provided for middle-aged and older subjects. Normal LVMT is lower for women than men. Observed values vary depending on the imaging plane for measurement. ... mean values by LV myocardial level (basal, mid-cavity, and apical),
