Electrophysiological findings after bilateral thoracoscopic atrial fibrillation ablation using irrigated bipolar radiofrequency energy – a pilot study

Popis výsledku v původním jazyce

Background: Thoracoscopic atrial fibrillation ablation (TARAFS) using irrigated bipolar radiofrequency energy (Medtronic Cardioblate Gemini-S) should result in wide isolation of the pulmonary veins (PVs) and posterior left atrial (LA) wall (the box-lesion technique). Electrophysiological findings after this technique using this instrumentation are not known. Methods and results: 22 patients with AF recurrence after bilateral TARAFS for persistent AF had a radiofrequency catheter ablation (CA) at least three months after TARAFS. Results: Out of 22 patients, the box lesion was not completed in 15 (68.2%) patients. 12 had no endocardial signs of any prior ablation, 2 had right pulmonary PVs isolated and 1 had left PVs isolated. At the end of CA, box lesion was finished in all 15 patients and AF non-inducibility was achieved in 18 patients. Conclusion: In a considerable number of patients with AF recurrence after TARAFS box lesion is not finished and no signs of prior ablation to guide a touch-up catheter ablation are found on electroanatomical voltage map. In majority of patients, additional ablation beside box lesion is needed to achieve AF non-inducibility.
