Step 1: initial reconstruction of the right ventricle and aortic
root. (2D intracardiac echo frames with the ICE beam visualized are
fused with CARTOSOUND reconstruction of some structures for the reader
to better understand the 3D anatomy and the relationship between right
and left structures).
Panel A : ICE catheter in “home view” neutral position.
Acquisition of TV tags, RV volume, AV in long axis view with
visualization of RCC and NCC. Panel B: ICE catheter rotated
counterclockwise (anterior) to acquire a more lateral portion of the
right ventricle (RV). Acquisition of other TV tags and other RV
contours. Panel C: ICE catheter rotated clockwise (posterior) to
acquire a more septal portion of the right ventricle (RV). Acquisition
of other TV tags and other RV contours. Delineation of aortic valvular
plane. Panel D: ICE catheter rotated more clockwise to acquire
the most septal portion of the right ventricle outflow tract (RVOT). The
aorta with aortic cusps (NCC and RCC) and left ventricle (LV) (at the
level of the outflow tract) are also visible on the same projection.
ICE: Intracardiac echocardiography, TV: tricuspid valve, RV: right
ventricle, AV: aortic valve, RCC: right coronary cusp, NCC: non coronary
cusp, LCC: left coronary cusp, PA: pulmonary artery.
