Echokardiographie Vena Contracta

Echokardiographie Vena Contracta: What You Need to Know

Echokardiographie vena contracta, also known as Vena Contracta Width (VCW), is a critical measurement used in the diagnosis and treatment of heart disease. This measurement is obtained by performing an echocardiogram or ultrasound of the heart, which is a non-invasive procedure that uses sound waves to create images of the heart.

What is Vena Contracta?

Vena contracta refers to the narrowing of a blood vessel or valve that leads to restricted blood flow. In the case of the heart, it refers to the narrowest point of blood flow through a damaged or diseased heart valve. The vena contracta width (VCW) is the distance between the two edges of this narrowest point.

Why is Vena Contracta Important?

The vena contracta measurement is important for the diagnosis and treatment of heart disease because it provides crucial information about the severity of heart valve disorders. The wider the vena contracta, the more severe the valve disorder. This information can help determine the best course of treatment for the patient, whether it be medication, surgery, or a combination of both.

Conditions That Require Vena Contracta Measurement

Echokardiographie vena contracta is most commonly used to diagnose and monitor the progression of heart valve disorders, including:

– Aortic stenosis: narrowing of the aortic valve that restricts blood flow from the heart.

– Mitral regurgitation: backflow of blood from the left ventricle to the left atrium due to a leaky mitral valve.

– Tricuspid regurgitation: backflow of blood from the right ventricle to the right atrium due to a leaky tricuspid valve.

– Pulmonary hypertension: high blood pressure in the arteries that supply the lungs, which can lead to right heart failure.

How is Vena Contracta Measured?

To measure vena contracta width, a specialist will perform an echocardiogram or ultrasound of the heart. The procedure involves applying a gel to the patient`s chest and using a transducer to send sound waves through the chest to create images of the heart. These images are then analyzed to determine the width of the vena contracta.


Echokardiographie vena contracta is an essential measurement for diagnosing and monitoring heart valve disorders. With this measurement, doctors can determine the severity of the condition and develop an appropriate treatment plan for the individual patient. If you have been diagnosed with a heart valve disorder, it is important to discuss the potential benefits of vena contracta measurement with your doctor.
