Rv medio lateral end diastolic dimension 4 3 cm rv end diastolic area 35 5 cm 2 maximal ra medio lateral and supero inferior dimensions 4 6 cm and 4 9 cm respectively maximal ra volume 33 ml m 2 35 89.
The thickness of the rv free wall is in the range of only 3 5 mm 13 14 and the rv mass is approximately one fourth of that of the lv.
What is the normal range.
Rvot in short axis view.
15 16 still owing to the lower impedance and greater distensibility of the pulmonary artery bed the rv can pump blood at the same rate and volume as the lv.
In end diastole the right ventricular free wall is normally less than 5 mm.
