We report a 55-year-old men patient with a primitive central nervous system non-Hodgkin lymphoma B cell (LNH PNSLC), treated with chemotherapy rituximab, methotrexate, and ibrutinib (first treatment) who developed a refractory ventricular arrhythmic storm two hours after the ibrutinib intake. Indeed, ibrutinib could be associated with severe and occasionally fatal cardiac events. The swift emergence of a ventricular electrical storm with cardiac arrest demanded the prompt initiation of veno-arterial extracorporeal membrane oxygenation to effectively navigate this critically ill patient toward recovery. This intervention was deemed imperative, given the absence of any available antidote for the effects of ibrutinib. Veno-arterial extracorporeal membrane oxygenation proved successful in rescuing this patient, resulting in a complete neurological recovery. Consequently, he was able to resume his chemotherapy treatment.
