What is this test?

This is a Doppler ultrasound measurement of the right upper pulmonary vein, which returns blood from the lungs to the left side of the heart. It measures maximum blood-flow velocity during systole and diastole, when the heart contracts and relaxes.

Why might I need this test?

It may be used to assess pulmonary vein blood flow as part of an echocardiogram. Your clinician may order it when evaluating heart failure, mitral valve disease, abnormal heart rhythms, or changes in heart pressure.

How is the test performed?

A technician places an ultrasound probe on the chest and uses Doppler technology to record blood flow in the right upper pulmonary vein. The waves are measured during the heart's systolic and diastolic phases.

How do I prepare for the test?

This test usually requires no special preparation. You may be asked to wear clothing that allows easy access to the upper chest, and you should follow any specific instructions provided by the imaging center.

Frequently asked questions

Does this test require a blood sample?
No. It is an ultrasound measurement performed during an echocardiogram, so no blood sample is needed.
What do systolic and diastolic mean here?
Systole is when the heart contracts, and diastole is when it relaxes. The test measures pulmonary vein flow during both phases.
Can one abnormal result diagnose a heart condition?
No. The measurement is usually interpreted alongside other echocardiogram findings, your medical history, symptoms, and examination.
