## What is normal LV mass on Echo?

70 ± 9 g/m
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 do you measure LV mass?

The M-mode LV mass was calculated using corresponding equations (ASE: LV mass = 0.8[1.04(LVD + IVS + PW)3 – LVD3] + 0.6 g; and Penn: LV mass = 1.04[(LVD + IVS + PW)3 – LVD3] – 13.6 g), and the 2D LV mass was calculated by applying the ASE M-mode equation.

What is LV mass?

LV Mass and LV Mass Index

LV Mass (g) = 0.8{1.04[([LVEDD + IVSd +PWd]3 – LVEDD3)]} + 0.6
RWT = 2 * PWd LVEDD

## What is normal LV size?

42 to 59 mm
These criteria classify the LV size as normal (men: 42 to 59 mm; women: 39 to 53 mm), mildly dilated (men: 60 to 63 mm; women: 54 to 57 mm), moderately dilated (men: 64 to 68 mm; women: 58 to 61 mm), or severely dilated (men: ≥69 mm; women: ≥62 mm).

What is normal thickness of left ventricle?

This study found that the LV was thickest in the basal septum (segment 3) with a mean thickness of 8.3 mm and 7.2 mm and thinnest in the midventricular anterior wall (segment 7) with 5.6 mm and 4.5 mm for men and women, respectively (16).

### Does LVH cause sudden death?

Significant left ventricular hypertrophy (LVH) increases the risk of sudden cardiac death 6- to 8-fold in men and 3-fold in women. In patients with definite electrocardiographic (ECG) evidence of LVH there is a 59% overall mortality at 12 years.

Can LVH cause death?

Typically, LVH resulting from hypertension does not predispose one to sudden death. However, patients who have severe LVH for no apparent reason, a condition called hypertrophic cardiomyopathy, may in some cases have a higher risk of sudden death.

## What is normal LV wall thickness?

What is a normal LVEF?

The left ventricle is the heart’s main pumping chamber. It pumps oxygen-rich blood up into your body’s main artery (aorta) to the rest of the body. A normal ejection fraction is about 50% to 75%, according to the American Heart Association. A borderline ejection fraction can range between 41% and 50%.

### 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 the 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 the normal LV end-diastolic volume?

Results: The normal ranges for LV end-diastolic volume measurements after adjustment to body surface area (BSA) were 62-120 ml for males and 58-103 ml for females.

## What is the index of the LV mass?

LV Mass and LV Mass Index. Left ventricular mass and left ventricular mass indexed to body surface area estimated by LV cavity dimension and wall thickness at end-diastole. Relative wall thickness (RWT) allows further classification of LV mass increase as either concentric hypertrophy (RWT >0.42) or eccentric hypertrophy (RWT ≤0.42).

How is left ventricular mass indexed to body surface area?

Left ventricular mass and left ventricular mass indexed to body surface area estimated by LV cavity dimension and wall thickness at end-diastole. Relative wall thickness (RWT) allows further classification of LV mass increase as either concentric hypertrophy (RWT >0.42) or eccentric hypertrophy (RWT ≤0.42).

### Why is LV mass an important risk factor?

The importance of LV mass also lies in the fact that it is an independent risk factor for cardiovascular morbidity; in fact, no other biological variable apart from age predicts cardiac risk better than LV hypertrophy. Domenic A. Sica, Barry L. Carter, in Hypertension: A Companion to Braunwald’s Heart Disease (Second Edition), 2013

How is LV mass underestimated in cube function?

The cube-function technique showed a consistent underestimation of LV mass of 14.3 g, and there were wide 95% limits of agreement (±57.6 g and ±46.3 g for cube-function and area-length techniques, respectively) when compared with 3D measurement.
