The case of a 68-year-old patient with recurrent perimitral atrial flutter to anti-arrhythmic therapy in the follow-up of pulmonary vein ablation due to atrial fibrillation is presented. In our case, arrhythmia control is not achieved despite a usual approach; Endo-epicardial radiofrequency application at the mitral isthmus level. Given the above, it was decided to alcoholize Marshall’s vein; a fast, useful and effective technique in the control of this arrhythmia. Here is a step-by-step guide to familiarize interventional cardiologists with this technique. The patient is in sinus rhythm and without recurrence of the arrhythmia at follow-up.
