Treatment of ventricular tachycardia in patient witha mechanical aortic valve by radiofrequency catheterablation via transseptal approach

We report a case of a 63-year-old man with incessant ventricular tachycardia (VT) who was treated by left ventricular (LV) mappingand radiofrequency catheter ablation. The ablation procedure was complicated since the patient had undergone aortic prostheticvalve surgery before. Left ventricular catheterization through the mechanical aortic valve is not routinely performed becauseof the risks involved as they may damage or ‘jam the occluder’. In our patient ablation of ventricular tachycardia was achievedvia transseptal approach and through the mitral valve. During the follow-up period of two years, the patient remained free fromimplantable cardioverter defibrillator shocks.
