(a) Parasternal long axis view (a) showed severe
concentric hypertrophy of interventricular septum (IVS) and LV free wall, but without an echogenic mass in the apex.
Many studies have found
concentric hypertrophy in the hearts of trained rats and mice, although their training protocols are controversial.

The overload of pressure can result in arterial hypertension, arteriosclerosis and, occasionally, aortic stenosis, causing LV
concentric hypertrophy (increase in mass secondary to increase in myocyte thickness, without significant alteration in ventricular volume and relative thickness).
Long-term hypertension is an influence on ventricular hypertrophy development, specifically
concentric hypertrophy (Verdecchia et al.
Transthoracic and transesophageal echocardiography revealed massive
concentric hypertrophy (Fig.
This remodeling finally results in the
concentric hypertrophy of LV, i.e.
In clinical understanding, the term "structural remodeling" refers usually to changes in the LVH shape in terms of eccentric and
concentric hypertrophy. However, the changed shape of the left ventricle is conditioned by underlying changes at tissue, cellular and subcellular levels and these changes have been reported already in early stages of hypertension and LVH, both in animal models and in humans (21, 22).
The left and right ventricles appeared to have
concentric hypertrophy with multiple, prominent myocardial trabeculations and deep intertrabecular recesses communicating with the main ventricular cavity (Fig.
