Hypertrophy Vicarious

Vicar hypertrophy (h. vicaria; lat. vicarius - replacing, replacing; syn. g. substitutive) is a compensatory increase in the size and functional activity of an organ or tissue, occurring as a result of insufficiency of the function of another organ associated with it.

For example, in chronic renal failure, hypertrophy of the remaining intact nephrons occurs, which take on additional functional load. Thus, hypertrophy of undamaged structures compensates for the lost or reduced function of the affected organ or tissue.

Vicarious hypertrophy is one of the mechanisms that allows the body to adapt to changed operating conditions and maintain homeostasis.

Hypertrophic vicarious cardiomyopathy is a relatively rare heart disease that is characterized by the growth of the heart muscle in the form of a cardiac chamber, or valve cavity, located in the posterior region between the ventricles of the heart and the right atrium. This disease can affect any of the four chambers of the heart. Hypertrophic vicarious cardiomyopathy may be accompanied by arrhythmias (abnormal heart rhythms) and cardiogenic shock, which can lead to heart attack, myocardial infarction, or sudden death. Treatment for hypertrophic vicarious cardiomyopathy may include surgery, medications, and lifestyle changes to control symptoms.
