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.
