Cardiomegaly is a medical condition wherein the heart is enlarged. It is generally categorized in the following manner:

Cardiomegaly due to dilation
Cardiomegaly due to ventricular hypertrophy
- Left ventricular hypertrophy (LVH)
- Right ventricular hypertrophy (RVH)
- Left atrial enlargement
hypothyroidism
Morquio's Syndrome and other related dwarfism diseases
Obesity
Patent ductus arteriosus (PDA)
PCOS, as in Polycystic Ovarian Syndrome
Pulmonary Vein Stenosis
Radiation
Sickle-cell disease
Type II glycogen storage disease (Pompe disease)
Uraemia
Myocardial fibroelastosis
Kawasaki disease
Pericardial effusion
Tumors of the heart
Drugs such as sulphonamides and doxorubicin
