Normal Values




Values provided below are from a range of sources. Wherever possible 2-D TEE values are given. In situations where these values are not available, or are poorly documented, transthoracic echocardiography (TTE) or M-mode values are given



Normal 2-D dimensions

































Aorta and Aortic Valve (End Diastole) Normal (± SD) (cm) Range (cm)
LVOT (TTE) 1.9 (0.2) 1.4–2.6
Aortic valve annulus (TTE) 1.9 (0.2) 1.4–2.6
Sinus of Valsalva (TTE) 2.8 (0.3) 2.1–3.5
Sinotubular junction (TTE) 2.4 (0.4) 1.7–3.4
Ascending aorta (TTE) 2.6 (0.3) 2.1–3.4
Descending thoracic (proximal) 2.1 (0.4) 1.4–3.0

















Pulmonary Artery (End Diastole)
Pulmonary valve annulus (TTE) 1.5 (0.3) 1.0–2.2
Main pulmonary artery (TTE) 1.8 (0.3) 0.9–2.9

















Left Atrium (ME Four-Chamber View)
Length (apex to mitral annulus) 3.8 (0.6) 2.0–5.2
Width (maximum dimension) 3.9 (0.7) 2.4–5.2

















Right Atrium (ME Four-Chamber View)

Width (maximum dimension) 3.8 (0.6) 2.9–5.3









































Left Ventricle (TG mid SAX view)
End systolic dimension (A–P) 2.8 (0.6) 1.8–4.0
End diastolic dimension (A–P) 4.3 (0.7) 2.3–5.4
End diastolic area 10.6–17.8 cm 2
Fractional area change 36–64%
Ejection fraction 55–75%
LV wall thickness (end diastole, M-mode, TTE)
