通过分享加拿大Southlake中心和其他中心的经验及数据,本文比较了缺血性心肌病(ischemic cardiomyopathy,ICM)和非缺血性心肌病(non-ischemic cardiomyopathy,NICM)室速消融的疗效,指出基于基质标测的射频消融对ICM患者室速消融的疗效要优于NICM患者。然而,要确定NICM的基质面临诸多挑战。与ICM患者相比,NICM患者室速消融的长期预后仍然较差。但如果把降低NICM患者室速发作负荷而不是完全治愈作为主要的消融终点,那么基质消融的疗效仍是可以接受的。
By sharing the experience and data of the Southlake Center in Canada and other centers, this article compares the effects of VT ablation on ischemic cardiomyopathy (ICM) and non-ischemic cardiomyopathy (NICM) Radiofrequency catheter ablation of ICMs is superior to NICM in the management of ventricular tachycardia in ICM patients. However, there are many challenges in determining the matrix of NICM. The long-term prognosis of VT ablation in NICM patients is still poor compared to ICM patients. However, if the reduction of VT load in NICM patients rather than complete cure as the primary endpoint of ablation, then the effect of matrix ablation is still acceptable.
