IDENTIFICATION OF LV AND RV ON ECHO

IDENTIFICATION OF CHAMBERS ON ECHO

LV is thick walled elliptical chamber and the largest chamber and forms apex.

RV is triangular in shape. Normally doesn't form apex and its size is 2/3rd of the LV and has a prominent muscular structure called moderate band which connects IVS to the anterior papillary muscles. RV is more trabeculated than LV.

RV size is  <2/3rd of LV (normal)

                   2/3rd to inferior of LV = mildly enlarged

                   Equal to LV = moderately enlarged

                   Size > LV  =  severely enlarged RV
