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

Table 5 Repeat ablation procedures in patient subgroups

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)

DCM dilated cardiomyopathy, HCM hypertrophic cardiomyopathy, ICM ischemic cardiomyopathy, SHD structural heart disease, VA ventricular arrhythmia
Values are n (%). *p <0.05 was considered statistically significant
Patients with completed follow-up (n = 256 out of 266); repeat ablation procedures of the initially ablated arrhythmia were analysed
