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
