septum and inferior septum.
Figure 1. Right ventriculography under fluoroscopic RAO30 (A, B
and C) and LAO45 (D) in a patient. Nine septal subdivisions are depicted
in the RAO30 image (A) following contrast injection that shows the RV
septum (B). LAO45 (D) shows the separation (the green line) between RV
and LV. The delivery catheter with MicraTM leadless
pacemaker is shown in Panels C and D.
