Cardiomegaly is a condition resulting in heart enlargement, and often occurs as a symptom of acquired cardiomyopathies (Amin & Siddiqui, 2020). The condition occurs when the transverse diameter of the cardiac silhouette is equal to or exceeds 50% of the transverse diameter of the chest on a computed tomography or chest radiograph (Amin & Siddiqui, 2020). Dilated cardiomyopathy is the main type of heart enlargement, where the heart ventricles become thin and stretched (Amin & Siddiqui, 2020). However, heart enlargement may also be caused by hypertrophy, where the ventricles thicken (Amin & Siddiqui, 2020). An enlarged heart may not pump blood efficiently which may lead to heart failure or further cardiovascular diseases and other symptoms (Amin & Siddiqui, 2020).
