RESUMO
Left atrial appendage occlusion (LAAO) in the treatment of atrial fibrillation (AF) has become a hot topic in clinical research in recent years. We report a 68-year-old female with a 3-year history of paroxysmal atrial fibrillation refractory to antiarrhythmic therapy and unable to tolerate anticoagulation therapy who underwent successful atrial fibrillation radiofrequency ablation combined with left atrial appendage occlusion guided by 3D printing technology. There was no recurrence of her atrial fibrillation and there was continued complete occlusion of her left atrial appendage at 3-month and 1-year follow-ups.This case supports the potential advantage of 3D printing technology to guide a "one-stop combined AF radiofrequency ablation and left atrial appendage occlusion procedure." But whether it can improve the prognosis and quality of life of patients, further multi-center research and large data statistics are required.
