AbstractCardiac pacing often turns out to be the only effective treatment of severe, life-threatening arrhythmias. We performed 77 living-donor liver transplantations (LDLT) from 1999 to 2007. In these cases, three recipients experienced fatal arrhythmia and required temporary cardiac pacing during the perioperative period. The first case was a 68-year-old woman diagnosed with liver cirrhosis and hepatocellular carcinoma (HCC). Her Model for End-Stage Liver Disease (MELD) score was 34. We performed LDLT using a right lobe graft. She showed complete atrioventricular block with cardiac arrest at postoperative day (POD) 42 after a bacterial infection. We performed a resuscitation and instituted temporary cardiac pacing. However, she was dead at POD 43. Pathologic findings at autopsy showed a diffuse myocardial abscess, which caused the fatal arrhythmia. The second case was a 58-year-old man diagnosed with HCC and liver cirrhosis; his MELD score was 9. We performed LDLT using a right lobe graft. He showed atrial fibrillation after septic shock. He also showed sinus bradycardia with a cardiac arrest at POD 10. We performed resuscitation and emergent temporary pacing. He recovered and was alive without recurrence of arrhythmia or infection. The third case was a 58-year-old woman diagnosed with multiple HCC. During preoperative regular check-up, she was diagnosed to have cardiac hypertrophy and was started on beta-blockers as treatment for cardiac hypertrophy. However, severe bradycardia necessitated temporary cardiac pacing. LDLT was performed safely after implantation of a pacemaker. Early use of temporary cardiac pacing for severe arrhythmias may be effective to maintain the hemodynamic state in LDLT.
