Concentric hyperophy of left ventricle is seen in

In pressure overload states (e.g., hypeension or valvular stenosis), new sarcomeres tend to be added parallel to the long axis of the myocytes, adjacent to existing sarcomeres. The growing muscle fiber diameter thus results in concentric hyperophy--the ventricular wall thickness increases without an increase in the size of the chamber. The chronic pressure overload of systemic hypeension causes left ventricular concentric hyperophy, often associated with left atrial dilation due to impaired diastolic filling of the ventricle. Persistently elevated pressure overload can cause ventricular failure with dilation. (Robbins Basic Pathology,9th edition,pg no.386,388)
