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 We also searched clinicaltrials.gov to identify ongoing and unpublished trials.
