Catheter-based radiofrequency (RF) ablation is an effective, well-established therapy for ventricular tachycardia (VT). However, a large number of patients still have recurrences, particularly those with substrates arising from intramural locations that are inaccessible through endo- or epicardial catheter approaches. Several unconventional ablation techniques have been proposed to treat RF-refractory VT, including transarterial coronary ethanol ablation and retrograde coronary venous ethanol ablation. We review the evidence regarding the mechanisms, procedural aspects, and alcohol ablation outcomes for ventricular arrhythmias.
基于导管的射频(RF)消融是治疗室性心动过速(VT)的一种有效且成熟的疗法。然而,仍有大量患者出现复发,尤其是那些具有源自壁内位置的基质的患者,这些位置无法通过心内膜或心外膜导管方法到达。已经提出了几种非传统的消融技术来治疗射频难治性室性心动过速,包括经动脉冠状动脉乙醇消融和逆行冠状静脉乙醇消融。我们综述了有关室性心律失常的机制、操作方面以及乙醇消融结果的证据。
