It is distinguished from hyperplasia, in which the cells remain approximately the same size but increase in number . Although hypertrophy and hyperplasia are two distinct processes, they frequently occur together, such as in the case of the hormonally - induced proliferation and enlargement of the cells of the uterus during pregnancy . </P> <P> Eccentric hypertrophy is a type of hypertrophy where the walls and chamber of a hollow organ undergo growth in which the overall size and volume are enlarged . It is applied especially to the left ventricle of heart . Sarcomeres are added in series, as for example in dilated cardiomyopathy (in contrast to hypertrophic cardiomyopathy, a type of concentric hypertrophy, where sarcomeres are added in parallel). </P>
