Prognostic Indicators in Cats with Hypertrophic Cardiomyopathy
Left ventricular hypertrophy was defined as LV septal or free wall end-diastolic thickness ≥6 mm,7 whether measured from 2D or M-mode images.29 Otherwise, M-mode images were used only to obtain LV fractional shortening (FS%) values, and 2D images were used for measuring maximal LV end-diastolic wall thickness from either the septum or free wall.

The regression analysis of echocardiographic dimensions with the same covariates demonstrated that the increase in heart mass was a consequence of increased wall thickness, rather than an

1. Determine the thickness required for the LP LVL beam and calculate the maximum reaction. 2. Select the appropriate table for 1-ply (1-3/4"), 2-ply (3-1/2") or 3-ply (5-1/4"). 3. Select a bearing length with a maximum reaction that meets or exceeds your calculated value. 4. Make sure the support is structurally adequate to carry the reaction.

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.
