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

Radiofrequency catheter ablation (RFCA) of atrial fibrillation (AF) in patients with prosthetic valve is still a challenge because of the higher recurrence rate and difficult manipulation of catheters in the left atrium which may lead to higher risk of complications. We presented the first AF ablation in Vietnam of a patient who had mitral and aortic mechanical valves.
