Radiofrequency catheter ablation of newly diagnosed paroxysmal atrial fibrillation in a patient with mitral and aortic mechanical valves: A case study

Background: Radiofrequency catheter ablation (RFCA) of atrial fibrillation (AF) in patients with prosthetic valve is still a challenge because the higher recurrence rate and difficult manipulation catheters left atrium which may lead to risk complications. We presented first AF Vietnam patient who had mitral aortic mechanical valves.
 Case summary:
 A 54-year-old man two heart valves (mitral aortic) implanted 16 years ago was newly diagnosed symptomatic paroxysmal for past 4 months at province general hospital. The treated amiodarone but could not tolerate medication. referral our centre made consideration radiofrequency ablation. Sinus rhythm successfully restored after pulmonary vein isolation, cavo-tricuspid isthmus ablation, tailor-ablation. At last follow-up 9-months post-ablation, sinus asymptomatic.
 Discussion: 
 Catheter valve(s) challenging due increased difficulty accessing as well inside atrium. Nevertheless, this procedure be safely performed high experience centres.
