(a) Correlation between TIVPD: total intraventricular pressure difference and LVL: longitudinal length of left ventricle, from endocardial border of the apex to midpoint of the mitral annulus. Significant positive correlation between TIVPD and LVL (R = 0.50, p < 0.05) was observed. (b) Correlation between TIVPG: total intraventricular pressure gradient and LVL. Statistical correlation was not seen between TIVPG and LVL.
