Cumulative ‘success’, ‘partial success’, ‘failure’ and ‘clinical success’ rates after 22 ± 14 months were 60%, 26%, 14% and 86%, respectively. Complications occurred in 15 patients – acutely in 11, during follow-up in four. Ultimately 167 procedures were performed until follow-up censure in May 2009. Outcomes were defined as: ‘success’ (no symptoms or Holter AF) ‘partial success’ (substantially reduced AF symptoms) ‘clinical success’ (‘success’ and ‘partial success’) ‘failure’ (no symptom improvement).Ī total of 100 consecutive patients (age: 49 years females: n=17 persistent AF: n=30 CHADS 2 score >1: n=7) underwent a first ablation (between January 2004 and May 2007). Treatment goals were to disconnect all pulmonary veins electrically and improve symptoms using a state-of-the-art ablation method. The outcome and complications of atrial fibrillation (AF) ablation in a UK patient cohort were investigated by offering symptomatic, drug-refractory patients ablation. ![]()
