Long-term outcomes of ventricular tachycardia ablation in ischemic and non-ischemic cardiomyopathy patients: Data from a single center ablation registry.

What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveCatheter ablation is effective in the treatment of ventricular tachycardia (VT). However, long-term outcomes after VT ablation in non-ischemic cardiomyopathy are sparsely described. We aimed to compare the outcomes of VT ablation between patients with ischemic cardiomyopathy (ICMP) and non-ischemic cardiomyopathy (NICMP).
methodsAcute procedural and long-term outcomes of 212 consecutive patients (ICMP, 135; NICMP, 77) who were ablated for sustained VT and followed for a median of 36 months were gathered and analyzed.
resultsCompared with patients with NICMP, patients with ICM were older, more likely to be men, had lower LVEF, more comorbidities, and had a higher number of inducible VTs. Complete procedure success was higher in patients from the NICMP group (88.3 % in NICMP compared to 79.3 % in ICMP). VT recurrence occurred in 54.8 % of ICMP compared to 38.9 % of NICMP (P value = 0.026). The overall mortality rate was 22 % in the ICMP group, compared to 7 % in the NICMP group (P value = 0.007). Additionally, cardiac mortality occurred significantly more in the ICMP group than in the NICMP group (19 % vs. 6 %) (P value = 0.011).
conclusionVT ablation in patients with NICMP was found to be an effective and safe approach, achieving acute procedural success in a noticeable number of patients using the currently available catheter mapping and ablation techniques with acceptable low procedural complications. Overall, procedural failures were significantly more frequent in ICMP patients than in NICMP and were consistent with unhealthier long-term outcomes.
