Figure and Video legends
Figure : Images were formed by merging of a 3D-Electroanatomic
mapping system (EnSite Precision™, Abbott) and the fluoroscopy. The
mapping catheter reaches the ventricular surface of the right coronary
cusp using the ‘reverse S’ curve via the antegrade transseptal approach
in the right (A) and left (B) anterior oblique views. In panels A and B,
only the aortic root with 3 cusps and the ascending aorta were merged.
In panels C and D, the left ventricular cavity was shown with the
earliest ventricular activation (dots) in the same region in the right
(C) and left (D) anterior oblique views. In panels E and F, combined
3D-Electroanatomic mapping (the aorta and the left ventricle) was merged
with the fluoroscopic image of the mapping catheter in the right (E) and
left (F) anterior oblique views.
Video : Six videos (A-F) corresponding to 6 panels in the
figure.
