Boston scientific became aware of an event involving a habib endohpb radio frequency ablation catheter through the article "hyperkalemia after endobiliary radiofrequency ablation for malignant biliary obstruction", by inoue t, et al.According to the literature, endoscopic transpapillary drainage failed because of tumor invasion to the duodenum, and endoscopic ultrasound-guided drainage was attempted.After penetrating the left intrahepatic duct via the stomach, a guidewire was passed through the lower bile duct stricture.The fistula was dilated using a 4-mm dilatation balloon catheter, and a habib endohpb radio frequency ablation catheter was inserted.Subsequently, the stricture was ablated at a power of 7 watts for 90 seconds.A metallic stent was deployed antegrade across the stricture, and a single-pigtail plastic stent was deployed across the fistula.The patients vital signs were stable during the procedure.However, severe bradycardia occurred 2 hours later with their heart rate plummeting below 20 to 30 beats per minute (bpm) and electrocardiogram showing flattened p-waves and prolonged qrs complex.A blood test revealed serum potassium levels of 7.4 meq/l, which had been 4.6 meq/l at pre-procedure.Calcium was administered immediately, and glucose-insulin therapy was initiated.One hour later, serum potassium levels decreased to 5.8 meq/l and stabilized at 4.8 meq/l 12 h later.The patients symptoms gradually improved.No further information has been obtained despite good faith efforts.
