Hypertrophy, Heart, Dog.

A, Narrowing of the pulmonary outflow tract caused by pulmonic valve stenosis has forced the right ventricle to contract with much more pressure. This increased workload has caused hypertrophy of the wall of the right ventricle, which is much thicker here than it would normally be. B, Note the increased size (hypertrophy) of myocytes in the overworked heart muscle.
