Quality of life and occurrence of atrial fibrillation in long-term follow-up of common type atrial flutter ablation: ablation with irrigated 5 mm tip and conventional 8 mm tip electrodes.

摘要: The ablation of common type atrial flutter is mainly performed by two approved techniques, whose efficacy and outcome in terms of quality of life have not been evaluated so far in a long-term follow-up study over years. A high proportion of patients suffer from coexistent atrial fibrillation, which may worsen the ablation result. The question arises whether one technique is more effective than the other when immediate ablation results, occurrence atrial fibrillation and life are compared. Considering these facts, it is reasonable to think about new strategies for common flutter the era concepts catheter ablation fibrillation. In retrospective study we detailed questionnaire in 132 patients who underwent ablation type between 1999 2004. Radiofrequency ablation was performed irrespective coexistent fibrillation either with an irrigated tip or 8 mm tip electrode. Acute outcome, and associated of life, pre-, under- post-ablation was compared different ablation groups. Recurrent tachycardia were re-evaluated 12 lead ECG analysis assessed for both 88 (67%) contacted answered questionnaire polling perceived benefits of the procedure. Of other 44 patients (33%); 4 (3%) had died, 7 (5.3%) moved, 33 patients (25%) could be included due to missing incoherent answers. Independent technique there acute and long-term success rate at about 95%. After mean 3 years of this benefit persists in spite recurrent tachycardia, (55/88 patients, 59.1%). Despite secondary tachycardia, there high significant symptomatic benefit state healthy and daily practice work, with a p-value < 0.0005. frequency of episodes symptom "tachycardia" were significantly reduced after flutter, p-values 0.003 0.002, respectively. Therefore need for hospitalization was significant reduced (p = 0.001). Comparison both approaches revealed that there was no difference related to incidence occurrence of accepted and applied techniques the ablation atrial flutter show excellent outcome under aspect life longterm follow-up. Three years after the procedure majority of consider intervention beneficial. Despite the relatively appearance long-term follow-up effect still traceable.
