Abstract

This case report describes our first experience performing percutaneous epicardial catheter ablation for Burugada syndrome in our hospital. We describe the good results achieved in this case. The patient was a man in his 30s with no remarkable medical history. However, his family history was notable for the sudden death of his grandfather at age 37 years and his father at age 27 years. While asleep, the patient experienced convulsions and lost consciousness. During emergency transportation, defibrillation was performed 7 times by the ambulance crew. When the patient arrived at our hospital, sinus rhythm was observed on ECG. During resuscitation, Burugada syndrome was diagnosed based on ECG findings. On hospital day 6, an internal cardioverter defibrillator was implanted. After discharge, the defibrillator operated 10 times, so we opted for ablation treatment. Fractionated potential of over 150 ms was confirmed in the right ventricular outflow tract. A low voltage zone of <1 mV could be mapped, and the same site was cauterized a total of 46 times. As a result, ST segment amplitude decreased significantly in lead V1 on ECG. Percutaneous epicardial catheter ablation performed with reference to Nademanee’s report achieved good results in this case of Burugada syndrome.
