• This is a 61-years-old male patient. He had paroxysmal atrial fibrillation (AF) for about 14 years, refractory to antiarrhythmic drugs (AAD). AF had persisted for two years, so the patient accepted a standard Wolf Minimaze operation, with bilateral pulmonary vein (PV) isolation and left atrial appendage exclusion, in Oct. 2008. After that, sinus rhythm only remained 21 days with oral amiodarone. This patient was referred to our center for radiofrequency catheter ablation in Oct. 2010. Left ventricle end diastolic dimension (LVEDD) was 55 cm, left atrium (LA) long axis dimension was 47 cm, and left ventricle ejection fraction (EF) was 61%. No residual PV potential could be recorded in four PVs. So under the guidance of 3D Carto system, linear ablation was performed in left atrium, including roof, septal, mitral valve isthmus, endocardial coronary sinus, and tricuspid isthmus line in right atrium. AF converted to sinus rhythm with a 200 j direct current electrical shock. After 7 month follow-up, 24 hours ECG examined every month, sinus rhythm remains. Six-minute walk incresed from 300 m to more than 500 m. LVEDD is 51 cm. LA is 37 cm, EF is 71%. In conclusion, after standard Wolf minimaze operation, AF could recur with 4 PVs complete electrical isolation. Again, after more substrate in left and right was destroyed by endocardial linear ablation, sinus rhythm could remain without AAD. The patient recovers to normal heart function with reversed heart remodeling.
