Figure 1: Fluoroscopic and 3-D images of catheter position at start of
AVNRT ablation in RAO and LAO projections.
RAO = Right Anterior Oblique, LAO = Left Anterior Oblique, RAA = Right
Atrial Appendage, ABL = Ablation catheter, CS = Coronary sinus catheter,
HIS = His catheter, SVC = Superior Vena Cava and IVC = Inferior Vena
Cava. Images A & B: relative catheter orientation and position in the
RAO 30-degree projection on fluoroscopy and 3-D mapping. C&D: relative
catheter orientation and position in the LAO 30-degree projection
respectively. C: relative catheter orientation and position on
fluoroscopy and 3-D mapping respectively.
