LV dimensions

Each echocardiogram include an assessment of LV dimensions, describing wall thickness and function. Good measurements are essential and may have implications for therapy. LV dimensions must be measured in PLAX, end-diastolic and end-systolic and valves (MV and AOV) are closed. The measurement is situated in the basal part of the LV by the chordae.

Eyeballing LVEF

Cardiac ejection fraction (EF) eyeballing may be the most accurate echocardiographic method for the assessment of left ventricular systolic function. Test yourself and learn by doing with this QUIZ.

LV diastolic function

Still a lot remains unclear about the pathophysiology of diastolic heart failure, which still lacks an effective treatment, with a high mortality rate associated with diastolic heart failure over the last decades. Diastolic heart failure is characterized by an increased LV diastolic stiffness. There are some important echocardiographic measurements that should be included in the standard ultrasound examination in order to a properly assessment of the LV stiffness.

Data are expressed as mean ± SD (95% confidence interval). Note that for e´ velocity in subjects aged 16 to 20 years, values overlap with those for subjects aged 21 to 40 years. This is because e´ increases progressively with age in children and adolescents. Therefore, the e´ velocity is higher in a normal 20-year-old than in a normal 16-year-old, which results in a somewhat lower average e´ value when subjects aged 16 to 20 years are considered.
* Standard deviations are not included because these data were computed, not directly provided in the original articles from which they were derived.
