Overview
Cardiomegaly is defined as an enlargement of the heart above its normal size. Cardiomegaly is generally first detected on chest X ray, and less often it is detected on routine physical examination. Cardiomegaly may be the first sign of an occult systemic or cardiovascular disease.
Diagnosis
Echocardiogram
Echocardiogram recommended for those patients presenting suspected valvular disease, chamber size, ventricular function, and wall motion abnormalities.
Other Diagnostic Studies
Exercise or pharmacologic stress testing may be indicated in those patients suspected of having coronary artery disease. Patients suspected of having valvular disease or coronary artery disease may need a cardiac catheterization for full evaluation following echocardiography.
Treatment
Surgery
In patients who are awaiting a transplant for end-stage symptomatic heart failure, implantable ventricular assist devices may serve as a temporary aid for compensation. Transplantation may be considered in a few cases.
