What is this test?

Left ventricular end-diastolic volume is an imaging measurement showing how much blood is in the heart’s main left pumping chamber when it is fully relaxed and filled just before contraction.

Why might I need this test?

This measurement may be used to evaluate heart enlargement, pressure or volume overload, weakened heart function, valve disease, and the heart’s response to treatment.

How is the test performed?

The volume is usually calculated from heart images obtained by echocardiography. Cardiac MRI may also be used when appropriate. The images allow the clinician to estimate the chamber’s dimensions and blood volume.

How do I prepare for the test?

No laboratory blood sample or fasting period is required. Follow the imaging center’s instructions, tell the care team if you have trouble with the positioning required for echocardiography, and inform them of any implanted devices or MRI restrictions if MRI is planned.

Frequently asked questions

Is this the same as ejection fraction?
No. End-diastolic volume measures how much blood fills the left ventricle before a heartbeat, while ejection fraction estimates the percentage of that blood pumped out with each contraction.
Does this test require a blood draw?
No. It is calculated from cardiac images, most commonly obtained with an echocardiogram.
Can a single abnormal result diagnose heart failure?
No. The result must be interpreted with other imaging findings, heart function measurements, symptoms, and your medical history by your clinician.
