Many differentiated and undifferentiated gastric cancers are associated with Helicobacter pylori infection. Therefore, as a primary prevention method, the early diagnosis of H. pylori gastritis and eradication of these bacteria can prevent gastric cancer. As a secondary prevention method, the early diagnosis of gastric cancer and endoscopic treatment can also contribute to reducing overall mortality. Gastric mucosal atrophy and intestinal metaplasia are important findings in patients with H. pylori gastritis. The accurate diagnosis of other characteristic findings is also important to comprehensively assess gastric cancer risk. The identification of precancerous lesions and early gastric cancer by evaluating endoscopic gastric cancer risk scores, based on the Kyoto classification of gastritis, is similarly important. Recently, endoscopic image evaluation systems equipped with artificial intelligence have been developed to complement the diagnostic abilities of individual endoscopists and reduce interobserver variability; future developments in this area are highly anticipated.

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.
