Lesion Characteristics After Pulsed-Field Ablation in Patients With Atrial Fibrillation and a Left Common Ostium
In Brief
An observational study evaluating Creating an electro-anatomical map for Atrial Fibrillation and 2 related conditions. Completed, enrolled 24 participants across 1 site.
Detailed Summary
This study aims to investigate the lesion characteristics after pulmonary vein isolation using pulsed-field ablation in patients with atrial fibrillation and a common of the left pulmonary veins. The main question it aims to answer is: In which percentage of the patients will pulsed field ablation result in successful isolation of the left common ostium? Nineteen patients will be prospectively included in OLVG. All patients will be treated with pulsed-field ablation (routine care). After the ablation procedure, an electro-anatomical map will be created using the ablation catheter and a mapping system. This map will display the left atrium and the lesion in detail. After the procedure, three experienced operators are asked to draw a line around the LCO in the anatomical map where they would have ablated if conventional radiofrequency ablation was used. The distance between the drawn line and the ablation lesion will be measured at three predefined points. The lesion is considered successful if the mean distance is within ±10mm at all measurement points.
