Why the study?
Outcomes of catheter ablation for ventricular tachycardia in patients with non-ischemic dilated cardiomyopathy required systematic evaluation across available studies.
Does catheter ablation of ventricular tachycardia improve short- and long-term outcomes in adults with non-ischemic dilated cardiomyopathy?
Does catheter ablation of ventricular tachycardia improve short- and long-term outcomes in adults with non-ischemic dilated cardiomyopathy?
Catheter ablation for ventricular tachycardia in patients with non-ischemic dilated cardiomyopathy is effective and safe, achieving acute complete procedural success in 65.5% of patients with a 5.8% complication rate, though VT recurrence remains notable at 34.2%.

VT ablation is effective and safe for refractory VT in NIDCM; supports use while extending observational data pending RCTs.
