In patients with mechanical aortic and mitral valves and left ventricular (LV) tachycardia (VT), catheter ablation is technically challenging due to the limited access to the LV. Promising new alternatives to radiofrequency ablation include pulsed-field electroporation, percutaneous or surgical sympathetic neuromodulation, and noninvasive stereotactic radioablation therapy (SBRT). We herein describe the effect of SBRT as a bailout therapy on the management of a challenging VT case in the presence of double left-sided mechanical valves.
对于患有机械主动脉瓣和二尖瓣且出现左心室（LV）心动过速（VT）的患者，由于进入左心室的途径有限，导管消融在技术上具有挑战性。射频消融有前景的新替代方法包括脉冲场电穿孔、经皮或手术交感神经调节以及非侵入性立体定向放射消融治疗（SBRT）。我们在此描述了SBRT作为一种补救疗法对存在双侧机械瓣膜的具有挑战性的VT病例管理的效果。
