## What is normal LV mass on Echo?

Normal values of LV mass indexed to body surface area were found to be 70 ± 9 g/m(2) in men and 61 ± 8 g/m(2) in women. Significant age and gender dependence, but no racial dependence, was observed for LV mass index. Conclusions: Three-dimensional echocardiography is an accurate method for measuring LV mass.

What does a high LV mass mean?

Summary: Elevated left ventricular mass, known as left-ventricular hypertrophy, is a stronger predictor of coronary artery disease-related death and heart failure than coronary artery calcium score, according to a new study.

How is LV mass measured in Echo?

LV volumes were derived by summation of discs and LV mass was calculated by subtracting endocardial from epicardial volume at end-diastole and multiplying by 1.05 g/cm3. All CMR measurements were interpreted by an experienced investigator (E.M.) who was blinded to the echocardiographic results.

### What is LV in 2D echo?

SUMMARY Two-dimensional echocardiography (2DE) was used to measure left ventricular (LV) end- diastolic volume (EDV), end-systolic volume (ESV) andLV ejection fraction (EF). Thirty closed-chest dogs. were studied in the control state and, of these, 11 were restudied 1 hour after proximal left anterior descending.

What are normal echocardiogram values?

Normal values for aorta in 2D echocardiography

Aortic annulus 20-31 mm 12-14 mm/m2
Sinus valsalva 29-45 mm 15-20 mm/m2
Sinotubular junction 22-36 mm 13-17 mm/m2
Ascending aorta 22-36 mm 13-17 mm/m2

How do you calculate LV mass?

Formulas

1. LV Mass = 0.8 x (1.04 x (((LVEDD + IVSd +PWd)3 – LVEDD3))) + 0.6.
2. LVMI (LV Mass Indexed to Body Surface Area) = LV Mass / BSA.
3. RWT (Relative Wall Thickness) = 2 x PWd / LVEDD.
4. BSA (Mosteller) = (((Height in cm) x (Weight in kg))/ 3600)½

## How is LVH diagnosed on Echo?

Echocardiogram can reveal thickened muscle tissue in the left ventricle, blood flow through the heart with each beat, and heart abnormalities related to left ventricular hypertrophy, such as aortic valve stenosis. MRI. Images of your heart can be used to diagnose left ventricular hypertrophy.

What is normal LV function?

A normal left ventricular ejection fraction (LVEF) ranges from 55% to 70%. An LVEF of 65%, for example means that 65% of total amount of blood in the left ventricle is pumped out with each heartbeat. Your EF can go up and down, based on your heart condition and how well your treatment works.

What is LV systolic function?

LV systolic dysfunction was defined as an ejection fraction (EF) of less than 40% by echocardiography. The recovery of LV systolic function was defined as recovery of the EF to a level of 40% or greater and a net increase in EF of 10% or greater.

### What is an abnormal echocardiogram?

The resulting image of an echocardiogram can show a big picture image of heart health, function, and strength. For example, the test can show if the heart is enlarged or has thickened walls. Walls thicker than 1.5cm are considered abnormal. They may indicate high blood pressure and weak or damaged valves.
