QUALITY-OF-LIFE AND OUTCOMES AFTER RADIOFREQUENCY HIS-BUNDLE CATHETERABLATION AND PERMANENT PACEMAKER IMPLANTATION - IMPACT OF TREATMENT IN PAROXYSMAL AND ESTABLISHED ATRIAL-FIBRILLATION

One hundred seven patients underwent atrioventricular (AV)-junctional ablation and pacing for atrial fibrillation, and 90 were alive 2.3 +/- 1.2 years later. Quality of life index (1.9 +/- 1.2 to 3.6 +/- 1.1; 3 .6 +/- 1.1; p < 0.001) and ease of activities of daily living (2 +/- 0 .4 to 2.4 +/- 0.3; p < 0.001) were significantly improved. Doctor visi ts (10 +/- 13 to 5.06 +/- 7; p < 0.03), hospital admissions (2.8 +/- 6 .8 vs 0.17 +/- 0.54; p < 0.03), and antiarrhythmic drug trials (6.2 +/ - 4 to 0.46 +/- 1.5; p < 0.001) decreased significantly after treatmen t. Congestive heart failure episodes decreased from 18 before to 8 aft erward. Twenty-eight of 36 patients with dual-chamber pacemakers remai ned in a dual-chamber mode at follow-up. Radiofrequency AV-junctional catheter ablation and pacing is a highly successful form of treatment for medically refractory atrial fibrillation.
