Although, this patient exhibited eccentric left ventricular hypertrophy, such alteration is recognized as an uncommon finding in subjects diagnosed with aortic stenosis, which usually causes concentric hypertrophy
secondary to the increased resistance imposed by the ventricular outflow tract obstruction.
We observed modest concentric hypertrophy
in the hearts of female adult mice perinatally exposed to DDT, likely a result of the hypertension (Monassier et al.
Most of the obese (84%) had LV concentric hypertrophy
Many studies have found concentric hypertrophy
in the hearts of trained rats and mice, although their training protocols are controversial.
2 At first, the heart can compensate through concentric hypertrophy
but, due to disease progression, becomes overwhelmed, causing a drop in the systolic left ventricular ejection fraction.
Most of these cats had left ventricular concentric hypertrophy
(LVCH) with a small minority identified with degenerative mitral valve disease.
Echocardiography showed mild concentric hypertrophy
of left ventricle; 3 months later she was readmitted with increasing muscle weakness and SOB.
In patients without a HTNRE, concentric hypertrophy
was seen in 16%, and eccentric hypertrophy was seen in 7.
M/F, n 16/14 Mean (range) age at diagnosis, years 46 (18-60) Left ventricular wall thickness, n 13-16 mm 5 (16%) 17-19 mm 7 (23%) >19 mm 18 (61%) Concentric hypertrophy

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.
