We present the first worldwide use of pulsed-field ablation (PFA) for ventricular tachycardia (VT) ablation via a retrograde approach.
The patient had previously failed conventional ablation of an intramural circuit underneath the aortic valve. The same VT circuit was inducible during the procedure. The Farawave PFA catheter and Faradrive sheath were used to deliver PFA applications.
Post ablation mapping demonstrated scar homogenization. There was no evidence of coronary spasm during PFA applications and no other complications occurred. VT was non-inducible post ablation and the patient has remained free of arrhythmia at follow-up.
PFA for VT via a retrograde approach is feasible and effective.
我们首次在全球范围内经逆行途径使用脉冲场消融(PFA)治疗室性心动过速(VT)。
该患者此前已接受主动脉瓣下壁内回路的常规消融治疗,但失败了。在该手术中可诱发出相同的 VT 回路。使用 Farawave PFA 导管和 Faradrive 鞘管进行 PFA 应用。
消融后标测显示瘢痕匀化。在 PFA 应用过程中没有发现冠状动脉痉挛的证据,也没有发生其他并发症。消融后 VT 不再可诱发性,患者在随访中未再出现心律失常。
经逆行途径行 PFA 治疗 VT 是可行且有效的。
