“…A few studies with small sample size reported the electrocautery/RF-assisted J-wire TSP technique but with equivocal results. 6,7 In addition, the use of intracardiac echocardiography (ICE) during AF catheter ablation or other interventional cardiac procedures has become more prevalent. Zero/minimized fluoroscopy AF ablation has been performed safely in many electrophysiology labs.…”

BackgroundApplication of electrocautery to a J‐wire is used to perform transseptal puncture (TSP), but with limited evidence supporting safety and efficacy. We conducted a prospective randomized controlled trial to evaluate the safety and efficacy of this technique.MethodsTwo hundred consecutive patients were randomized in a 1:1 fashion to either the ICE‐guided electrified J‐wire TSP group or a conventional Brockenbrough (BRK) needle TSP group. The TSP was performed with a 0.032″ guidewire under 20 W, “coag” mode and was compared to TSP using the BRK needle. The primary safety endpoints were complications related to TSP. The primary efficacy endpoints included the TSP success rate, the total TSP time, and the total procedure time.ResultsAll patients complete the procedure safely. The electrified J‐wire TSP group had a significantly shorter TSP time than BRK needle TSP group. The total procedure time, number of TSP attempts required to achieve successful LA access, width of the intra‐atrial shunt at the end of ablation were similar between the two groups. The incidence of new cerebral infarction detected by MRI were similar between the two groups (3/32 patients in the J‐wire TSP group and 2/26 patients in conventional BRK TSP group, p = .82). And no difference in the incidence of residual intra‐atrial shunt (4.3% vs. 6%, p = .654) during the 3‐month's follow up.ConclusionUsing an electrified J‐wire for TSP under the guidance of ICE appears to be as safe as and more efficient than conventional BRK needle TSP, which may be especially useful in the era of non‐fluoroscopy AF ablation.

Background: Application of electrocautery to a J-wire is used to perform transseptal puncture (TSP), but with limited evidence supporting safety and efficacy. We conducted a prospective randomized controlled trial to evaluate the safety and efficacy of this technique. Methods: 200 consecutive patients were randomized in a 1:1 fashion to either the ICE-guided electrified J-wire TSP group or a conventional Brockenbrough (BRK) needle TSP group. The TSP was performed with a 0.032″ guidewire under 20W, “coag” mode and was compared to TSP using the BRK needle. The primary safety endpoints were complications related to TSP. The primary efficacy endpoints included the TSP success rate, the total TSP time, and the total procedure time. Results: All patients complete the procedure safely. The electrified J-wire TSP group had a significantly shorter TSP time than BRK needle TSP group. The total procedure time, number of TSP attempts required to achieve successful LA access, width of the intra-atrial shunt at the end of ablation were similar between the two groups. The incidence of new cerebral infarction detected by MRI were similar between the 2 groups (3/32 patients in the J-wire TSP group and 2/26 patients in conventional BRK TSP group, p=0.82). And no difference in the incidence of residual intra-atrial shunt (4.3% versus 6%, p=0.654) during the 3-month’s follow up. Conclusion: Using an electrified J-wire for TSP under the guidance of ICE appears to be as safe as and more efficient than conventional BRK needle TSP, which may be especially useful in the era of non-fluoroscopy AF ablation.
