An electrical storm due to malignant ventricular tachycardia (VT) is a life-threatening condition that requires catheter ablation (CA). Most VT arrhythmias evolve over time after acute myocardial infarction, coronary artery bypass grafting, or chronic heart failure. Clinically, only radiofrequency can identify and block all arrhythmia origin points. The procedure necessitates continuous induction in patients, resulting hemodynamic instability; therefore, extracorporeal membrane oxygenation (ECMO) support required. Earlier studies have reported substantial mortality rates; however, our results are significantly more favorable. In this study, we combined the minimally invasive circulation (MiECC) approach with ECMO preserve an appropriate flow rate, thus reducing intraoperative left afterload. We report 21 cases illustrating usefulness of modified veno-arterial (VA)-ECMO scenario.Data patients supported by VA-ECMO system (MiECC system) during CA Wuhan Asia Heart Hospital between June 2020 July 2021 were reviewed retrospectively.Successful was achieved 20 out (95%). median for implantation 206 min. Only two experienced complications post-treatment. All made complete recovery discharged. alive at 1-year-follow-up.Our helped restore systemic experiencing storm, achieving greater stability CA. Pre-insertion achieve even better results.
