Aims
In the SCALAF trial, catheter-based pulmonary vein isolation (PVI) was as effective in long-term prevention of atrial fibrillation (AF) as minimally invasive thoracoscopic PVI and left atrial appendage ligation (MIPI). Catheter ablation (CA) resulted in significantly less major complications as compare to MIPI. We report quality of life (QOL) outcome in these patients.
Methods
In this study, 52 patients with symptomatic paroxysmal or early persistent AF were randomized to either MIPI or CA. QOL was assessed at baseline, 3, 6, and 12 months follow-up using the SF-36 Health Survey Questionnaire. AF-related symptoms were quantified at each follow-up visit using the European Heart Rhythm Association (EHRA) score.
Results
Median age was 57 years and 78% was male. Paroxysmal AF was present in 74%. At 3 months follow-up, physical role limitations (88.2 ± 29.5; versus 40.9 ± 44.0; P = 0.001, respectively) and bodily pain scores (95.5 ± 8.7; versus 76.0 ± 27.8; P = 0.021, respectively) were significantly higher after CA compared to MIPI, indicating less limitation in daily activity caused by physical problems and less pain after CA than after MIPI. AF symptoms assessed by the EHRA scores improved significantly at 3, 6, 12, and 24 months compared to baseline in both treatment groups (P < 0.001), with no significant differences between treatment groups.
Conclusions
CA and MIPI ablation of AF both resulted in an improvement in several QOL measurements, although CA resulted in significantly less physical problems and bodily pain 3 months after treatment compared to MIPI.
