PANEL A and B. RAO and LAO fluoroscopic projections during a
coronary sinus angiogram performed via pump-injection through a right
coronary artery angiogram catheter (RCA). The radio-frequency ablation
catheter (RF) is placed inside the diverticulum via right femoral vein
access. A decapolar catheter is placed in the main body of the coronary
sinus (CS). PANEL C . Intra-cardiac ECMs during the successful
radiofrequency ablation with an irrigated-tip catheter. The pathway was
immediately eliminated once the radiofrequency lesion started.

(electrograms) and 3D electro-anatomical activation map in a young
patient with a Mahaim accessory pathways during the repeated ablation
procedure.
