Search strategy
We searched PubMed, Embase, and Cochrane Central Register of Clinical
Trials (Cochrane Library, Issue 5, 2020) to identify studies evaluating
the outcomes of patients with prior myocardial infarction that
presenting with VT that were randomized to first-line therapy with
catheter ablation or medical therapy. We used the terms: (“ventricular
tachycardia” OR “VT” OR “ventricular fibrillation” OR “VF” OR
“ventricular tachyarrhythmia”) AND (“ischemic cardiomyopathy” OR
“ICM” OR “myocardial infarction” OR “MI”) AND (“catheter
ablation” OR “CA” OR “radiofrequency ablation”). Our search was
restricted to human studies, published in peer-reviewed journals up to
April 2020. No language restriction was applied. The reference lists of
identified articles were also reviewed. We also searched
clinicaltrials.gov to identify ongoing and unpublished trials.
