Papillary muscles (PMs) were reported to be origin of ventricular arrhythmia (VA). Radiofrequency (RF) ablation was reported to be acutely effective in eliminating VA. However, the recurrence rate is high. Recently, cryoablation guided by intracardiac echocardiography, 3-dimensional mapping system, and image integration was introduced as alternative strategy for this challenging ablation. We present a case of ventricular tachycardia originating from anterior PM of left ventricle treated by cryoablation guided only by intracardiac echocardiography.

During ablation of re-entrant ventricular tachycardia (VT) 3-dimensional mapping systems are now used to properly delineate the scar tissue and aid ablation of scar-related VT. The aim of our study was to outline how the mode of ablation predicts success and recurrence in large scar-related VT. When comparing patients with recurrence and patients with no recurrence, univariate analysis showed that number of ablation lesions (28 ± 8 vs. 12 ± 8, P = 0.01) and more linear ablation lesions rather than focal lesions ( P = 0.03) were associated with long-term success. We demonstrated that more extensive ablation lesions and creation of linear lesions is associated with better success rate and lower recurrence rate during ablation of large scar-related ventricular tachycardia.

Introduction: Utilizing a 3-dimensional (3-D) mapping system and intracardiac echocardiography (ICE) has allowed ablation procedures with less or without fluoroscopy; however, there is limited data for patients with cardiac electronic implantable device (CIED) leads regarding the suspected risk of lead injury. Therefore, we sought to explore technics to perform safe trans-septal approach and catheter manipulation technique in patients with CIED leads. Methods and Results: This study comprised 68 consecutive patients (45 [66.2%] males, median [interquartile range] 73 [68–77] years old) with CIED who underwent catheter ablation for supraventricular tachycardia, 16 without fluoroscopy (zero-fluoro group) and 52 with fluoroscopy (conventional-fluoro group), between July 2019 and April 2021. All procedures were performed under a 3-D mapping system and ICE guidance. We compared the differences in treatment and development of complications between the two groups. The procedures were mainly atrial fibrillation (73.6%) and atrial tachycardia. The median time from venipuncture to trans-septal procedure (zero-fluoro vs. conventional-fluoro group: 27.0 min vs. 23.5 min, P=0.71) and total procedure time (215 min vs. 172 min, P=0.55) were not different between the two groups. The acute procedural success rate (100% vs. 98.1%, P=1.00) and reduction of atrial high-rate episodes at 6 months (3.2 [0.3–93.9]% vs. 1.0 [0.0–14.9]%, P=0.33) did not differ between the two groups. No patient showed lead-related complications in both groups. Conclusions: Zero-fluoro ablation for supraventricular arrhythmia using 3-D mapping and ICE in patients with CIED leads was feasible under careful catheter manipulation.
