1. Looping of heart
D or L loop?

2. Right ventricle & Right hand
 We are talking about normal looping
 Now choose your right hand only
 Keep the hand in the right ventricle only
D-l00p
ventricle
 Do not worry or forget on which side this right ventricle exists
 Do not worry or forget what makes outflow tract(aorta or PA)
 Your thumb must look inlet
 Your fingers must look outflow tract
 If your right thumb exactly fits inlet and fingers tip in outlet
 Your doubt is gone ,jump and declare it is D-Loop of ventricle

3. D-Loop
Ventricle
 Anatomical RV is on the RT side of anatomical LV
 There is nothing to do in relation to midline of body
 Looping of heart means the relation of left and right ventricle
in term of their location to each other

4.  We are talking about L- looping of ventricle
Right ventricle & Left hand
 Now choose your left hand only
 Keep the hand in the right ventricle only
 Do not worry or forget on which side this right ventricle exists
 Do not worry or forget what makes outflow tract(aorta or PA)
 Your left thumb must look inlet
 Your left medial four fingers must look outflow tract
 If your left thumb exactly fits inlet and left fingers tip in outlet
 Declare it is L-loop of ventricle=CCTGA

5.  Anatomical RV is on the LT side of anatomical LV
L-loop of
ventricle
 There is nothing to do in relation to midline of body
 Looping of heart means the relation of left and right ventricle
in term of their location to each other

6. Oh!
Now got it.
