Table 5 Repeat ablation procedures in patient subgroups

From: Outcome of catheter ablation of non-reentrant ventricular arrhythmias in patients with and without structural heart disease

Subgroup (total n = 256)Patients with repeat ablation (n = 40)p value (SHD subgroup vs. no SHD)
Patients with ICM (n = 42)6 (14.3)0.801
Patients with DCM (n = 25)8 (32.0)0.022*
Patients with HCM (n = 11)2 (18.2)0.643
Patients with myocarditis (n = 12)3 (25)0.220
Patients with other SHD (n = 12)1 (8.3)> 0.999
Patients without SHD (n = 154)20 (13.0) 
  1. DCM dilated cardiomyopathy, HCM hypertrophic cardiomyopathy, ICM ischemic cardiomyopathy, SHD structural heart disease, VA ventricular arrhythmia
  2. Values are n (%). *p <0.05 was considered statistically significant
  3. Patients with completed follow-up (n = 256 out of 266); repeat ablation procedures of the initially ablated arrhythmia were analysed
