A: Left anterior oblique fluoroscopic image showing a successful ablation site (red arrow) in twin A. A decapolar catheter is placed in the coronary sinus (blue arrow). A quadripolar catheter in the right ventricle is shown in black. B: Left anterior oblique fluoroscopic image showing a successful ablation site (red arrow) in twin B. A quadripolar catheter is located at the His-bundle (orange arrow). A decapolar catheter in the coronary sinus is shown in blue. Dashed circle represents the approximate location of the tricuspid annulus. TA = tricuspid annulus
