Management of patients with nonischemic cardiomyopathy (NICM) and ventricular tachycardia (VT) remains challenging. The role of catheter ablation for VT continues to evolve for these patients. Prior reports have described the location of the arrhythmogenic substrate for patients with NICM to be frequently located along the basal left ventricle, with an epicardial predilection. Furthermore, predictors for identifying whether mapping the endocardium or epicardial surface of the heart have been identified for improved success of VT ablation in this patient population. This chapter will review the latest advances in catheter ablation of ventricular tachycardia in patients with NICM.
非缺血性心肌病(NICM)和室性心动过速(VT)患者的管理仍然具有挑战性。对于这些患者,导管消融治疗 VT 的作用仍在不断发展。先前的报告描述了 NICM 患者的心律失常基质位置通常位于基底左心室,并伴有心外膜倾向。此外,还确定了一些预测因素,可以确定在这一患者群体中,为提高 VT 消融的成功率,是对心内膜还是心外膜表面进行标测。本章将回顾 NICM 患者 VT 导管消融的最新进展。
