About this study
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?
Read more
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.
Read the detailed description
Atrial fibrillation (AF) is the most common arrhythmia affecting millions worldwide with increasing prevalence. Patients with AF tend to have more comorbidity and an increased stroke and mortality risk. Pulmonary vein isolation (PVI) has become the cornerstone in the invasive treatment of atrial fibrillation (AF). It has been shown that PVI is more effective in maintaining sinus rhythm and improving quality of life compared to antiarrhythmic drugs. Although PVI results in a 98% burden reduction, an AF recurrence is observed in about half of the patients. AF type, comorbidity, and anatomical pulmonary vein variants affect arrhythmia-free survival.
Eighteen per cent of the patients undergoing PVI have a left common ostium (LCO) of the pulmonary veins.(16) A large ostium characterises an LCO, and single-shot devices tend to have worse arrhythmia-free survival than conventional radiofrequency (C-RF) ablation. A proper pulmonary vein occlusion is crucial during cryoballoon ablation. A large ostium can form a distal lesion with the possibility of pulmonary vein potentials proximal to the lesion resulting in AF recurrence. Wide antrum isolation has been shown to improve outcomes, and a distally located lesion can explain the higher AF recurrence rate.(18)
Farapulse (Boston Scientific, MA, US) pulsed-field ablation (PFA) was recently introduced. PFA uses short pulses of high voltages to achieve electroporation and irreversible cell membrane damage.(19) This technique is tissue-specific and limits collateral damage. While PV reconnection has been observed in 47% of patients who underwent cryoballoon or radiofrequency ablation, PFA ablation creates durable lesions in 86% of patients.(19, 20)
Tissue contact is less critical during PFA than conventional RF or cryoballoon ablation. Therefore one could hypothesise that, in patients with an LCO, PFA can be performed at the actual pulmonary vein ostium and that the lesion location is comparable to conventional RF ablation. Reddy et al. included patients with an LCO and presented an electro-anatomical map showing antral isolation. However, it is still being determined how many patients with an LCO were included, and a comprehensive description of the lesion still needs to be provided. Because no studies investigated the lesion characteristic in patients with AF and an LCO after PFA ablation, this study is designed to examine the lesion location in detail with an electro-anatomical map.
This single-centre study will be conducted prospectively in OLVG, Amsterdam, the Netherlands. Patients are eligible for this study if they are admitted for AF ablation because of symptomatic and drug-resistant/intolerant AF and have an LCO (identified by computer tomography (CT) or magnetic resonance imaging (MRI)). All inclusion and exclusion criteria are described in the paragraph ELIGIBILITY.
The operator will map the left atrial voltage in nineteen patients using the Ensite Precision (Abbott inc. IL, US) and the Farawave ablation catheter. First, all patients will be treated with pulsed-field ablation (routine care). Then, when all pulmonary veins are considered isolated, an electro-atomical map of the left atrium will be created.
After the procedure, three experienced operators are asked to draw a line in the anatomical map where they would have performed ablation if C-RF had been used - again, blinded for voltage. Next, the investigators will measure the distance between the line the operators drew and the ablation lesion at three points. The lesion is considered within range if the mean difference is ±10mm at all measurement points.

Clinical summary
The research question as the sponsor registered it. This describes what the study plans to test, not what it found.
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.

Questions about this trial
What is this clinical trial studying?
An observational study of Atrial Fibrillation and Pulmonary Vein Isolation, run by Onze Lieve Vrouwe Gasthuis at 1 site in Netherlands.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 7 inclusion and 21 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: finished, as of the sponsor's last update on 6 Mar 2024. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in Netherlands. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Successful left common ostium isolation after pulsed-field ablation in patients with atrial fibrillation (time frame: Within one week after the procedure). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05812261, which also lists 13 linked publications.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Mar 2024.
