Microcardia
As Mikrokardie (from ancient Greek μικρός Mikros , German , small ' and καρδία cardiac , German , Heart ' ) refers to the reduction of the cardiac silhouette in the X-ray image . Microcardia is usually not caused by a heart disease or malformation, but by a lack of fluids due to bleeding , vomiting, or diarrhea . In addition, microcardia is a common finding in adrenal insufficiency and in newborns with adrenogenital syndrome . Cardiac microcardia occurs in chronic debilitating infections, severe malnutrition, or end-stage cancer .
Apparent microcardia is caused by expansion of the mediastinum as a result of overinflation of the lungs in bronchial asthma or bronchiolitis .
The term is unusual in human medicine . One would simply designate a heart that is too small ( smallness of heart ).
