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.
