An enlarged heart (cardiomegaly) can be caused by damage to the heart muscle or any condition that makes the heart pump harder than usual, including pregnancy. Sometimes the heart gets larger and becomes weak for unknown reasons.
In this heart muscle disease, the heart's main pumping chamber stretches and can't pump blood well. Learn about the causes and treatment.
An echocardiogram shows blood flow through the heart chambers and helps determine how well the heart is working. Exercise tests or stress tests. These tests often involve walking on a treadmill or riding a stationary bike while the heart is monitored.

Hypertrophic cardiomyopathy typically affects the wall between the two bottom chambers of the heart. This wall is called the septum. The chambers are called the ventricles.
Enlarged heart, in heart failure If the heart weakens, as it can with heart failure, it begins to enlarge. This forces the heart to work harder to pump blood to the rest of the body.

A typical heart has two upper and two lower chambers. The upper chambers, the right and left atria, receive incoming blood. The lower chambers, the more muscular right and left ventricles, pump blood out of the heart.
An atrial septal defect (ASD) is a hole between the heart's upper chambers. The heart problem is present at birth. It is a type of congenital heart defect.
