The use of extracorporeal membrane oxygenation (ECMO) in the setting of haemodynamically unstable VT may allow rhythm stabilization and can be effective in providing haemodynamic stability during VT ablation procedures.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Case summary<\/jats:title>\n                  <jats:p>We describe the clinical course of a patient with ischaemic cardiomyopathy and recurrent VTs in the early post-myocardial infarction (MI) period. Nineteen days after MI, the patient started to experience recurrent attacks of VT, which became more frequent and non-responsive to medical treatment including amiodarone and lidocaine. The patient developed cardiogenic shock and a decision was made to institute ECMO. The patient was supported with ECMO for 32\u2009days because of heart failure, refractory VT, and recurrent infections. An electrophysiological study was performed 4\u2009days after ECMO initiation, which revealed a large scar area in the left ventricle. Radiofrequency energy was applied 69 times, rendering the VT non-inducible. Subsequently, VT attacks disappeared and the patient was weaned from ECMO after 32\u2009days. The patient received a left ventricular assist device 5\u2009days post-ECMO weaning and was then transplanted.<\/jats:p>\n               <\/jats:sec>\n               <jats:sec>\n                  <jats:title>Discussion<\/jats:title>\n                  <jats:p>There is still no evidence or guidelines regarding patients with refractory VT; however, ECMO support has been successfully used during VT ablation procedures. In this case report, VT ablation had a crucial role in treating the culprit arrhythmia while the implementation of ECMO allowed a complex ablation procedure to be completed safely.<\/jats:p>\n
