A: A 12-lead electrocardiogram of preexcitation recorded during atrial pacing. B: Intracardiac recordings from ablation catheter (AC) and intracardiac return electrode (IRE) at the site of bipolar ablation. C: Fluoroscopic image (left anterior oblique 30°) of bipolar ablation site. AC and IRE are located on both sides of posteroseptum, slightly above the level of coronary sinus (CS) ostium. D: Bipolar application (40 W titrated up to 45 W) led to elimination of the accessory pathway in 11 seconds, preceded by progressive loss of preexcitation during radiofrequency (RF) delivery. Bipolar RF catheter ablation (Bi-RFCA) was continued up to 120 seconds. Maximal temperature of IRE during Bi-RFCA was 46°C.
