[Successful RF ablation of permanent VT in a patient with acute coronary syndrome treated by complex angioplasty and stent implantation].

We describe a case of a 59-year-old male with permanent VT in the course of an acute coronary syndrome. Coronary angiography revealed acute occlusion of the right coronary artery. Although the underlying condition was treated by implantation of 4 stents with excellent haemodynamic effect (TIMI 3), the tachycardia continued, being refractory to drugs (amiodarone). The attempts to restore sinus rhythm by DC electrical cardioversion or transvenous pacing were unsuccessful. The patient was referred to the EP lab. A critical isthmus localised at the paraseptal region of the LV and parallel to the mitral annulus was identified. The isthmus was closed by linear RF application, resulting in VT termination. Due to impaired LV ejection fraction (<30%) the patient was scheduled for ICD implantation. During 6-week follow-up the patient remained free of arrhythmia.
