Candil JJ, Castro JC, Hernández J, et al. - By performing this multicenter study, researchers investigated how the timing of radiofrequency catheter ablation (RFCA) could impact 30-day mortality of patients with electrical storm (ES) and previous scar-related systolic dysfunction. This study involved 104 patients attended consecutively because of an ES due to monomorphic VT. RFCA was received by 64 patients (mean time from admission=83±67 hours) and 40 were not treated with RFCA. Findings showed that a reduction in 30-day mortality was observed in relation to RFCA performed >48 hours following admission in high risk patients with ES. In such individuals, the likelihood of successful RFCA rises when done under extracorporeal membrane oxygenation support.
