Your doctor may order an echocardiogram for a variety of reasons. Many other things can be picked up on echocardiography which makes it such a great tool for helping your cardiologist understand your heart’s health!
Overall the structure and function of the heart is studied during the exam. Below is some of the information which may be obtained.
Squeezing or pumping function of the heart (systolic function)
- If you have heard he term “E.F.”, this stands for Ejection Fraction, and is how the pumping efficiency of the heart is described.
- Typically an Ejection Fraction greater than 55% is considered normal.
- Congestive heart failure can result from lower than normal squeezing function or ejection fraction.
Relaxing or filling function of the heart (diastolic function)
- The ability of the heart to relax and fill with blood can change over time as the heart “stiffens” with age.
- This may cause symptoms in some patients, frequently shortness of breath. Other problems however, may lead to issues with the relaxation or “filling phase” of the heart including heart attacks among others.
Valve disease: Valve problems typically comes in two main varieties, which in turn can be due to several different problem:
- Leaking of the Heart Valves (Regurgitation) This problem results in too much blood flowing backwards across a heart valve. This can lead to heart failure, enlargement of heart chambers as well as rhythm disorders, among other troublesome issues. A mild degree of leaking is typical for some heart valves so don’t worry if you see that in your report.
- Tightening of the Heart Valves (Stenosis) This tends to occur when a heart valve becomes too thickened and/or hardened most commonly through deposits of calcium over time. This leads to trouble with the flow of blood forward from one chamber to another and pressure builds up behind the affected valve. Some people are born with stenotic valves which can cause problems early in life.
