Information from the echocardiogram may show:

• Changes in your heart size. Weakened or damaged heart valves, high blood pressure or other diseases can cause the chambers of your heart to enlarge or the walls of your heart to be abnormally thickened.
• Pumping strength. The measurements obtained from an echocardiogram include the percentage of blood that's pumped out of a filled ventricle with each heartbeat (ejection fraction) and the volume of blood pumped by the heart in one minute (cardiac output). A heart that isn't pumping enough blood to meet your body's needs can lead to symptoms of heart failure.
• Damage to the heart muscle. An echocardiogram helps your doctor determine whether all parts of the heart wall are contributing normally to your heart's pumping activity. Areas of heart wall that move weakly may have been damaged during a heart attack, or be receiving too little oxygen.
• Valve problems. An echocardiogram can help your doctor determine if your heart valves open wide enough for adequate blood flow or close fully to prevent blood leakage.
• Heart defects. An echocardiogram can show problems with the heart chambers, abnormal connections between the heart and major blood vessels, and complex heart defects that are present at birth.
