About this study

Official title: Evaluation of Mechanical Ventilation Methods Applied During the Procedure in Pediatric Cardiac Radiofrequency Ablation Interventions: Prospective Observational Study

The aim of this study is to describe the results of cardiac radiofrequency ablation under general anesthesia.

to evaluate mechanical ventilation methods in pediatric patients. The main questions it aims to answer are

  1. Whether lower tidal volume high frequency mechanical ventilation effects the success of radiofrequency ablation in pediatric cardiac arryhtmia patient?
  2. The effect of mechanical ventilation strategies on the number of effective lesions, radiofrequency ablation time and arrhythmia recurrence in the first month
Read the detailed description

Radiofrequency ablation (RF) is an effective method for the threatment of cardiac arrhythmias in pediatric patients. General anaesthesia and mechanical ventilation is the most common anesthesia management for pediatric arrhythmia patients. During the prosedure, thoracic excursion results in displacement of the catheter and disrupts the catheter stability which is crucial for quality of contact force (CF), sufficient ablation and safety. To minimize the thoracic excursion, high frequency low tidal volume ventilation and apnea ventilation may be needed during radiofrequency ablation. According to investigators knowledge there are studies about ventilatory strategies in adult patients who underwent cardiac radiofrequency ablation. However, there are no studies corcerning pediatric patients. In this study investigators aimed to investigate best ventilatory strategy for minimize thoracic excursion in pediatric patients with general anaesthesia. In this study investigators are going to observe 3 different ventilation strategies on radiofrequency ablation.

  1. Lung protective mechanical ventilation with 7-9 ml/kg tidal volume,
  2. Low tidal volume (4 ml/kg) high frequency mechanical ventilation
  3. Apnea ventilation during radiofrequency ablation

Questions about this trial

What is this clinical trial studying?

An observational study of Radiofrequency Catheter Ablation, run by Izmir City Hospital at 1 site in Turkey (Türkiye).

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 3 inclusion and 6 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: under way, not looking for participants, as of the sponsor's last update on 29 Jan 2026. 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 Turkey (Türkiye). 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?

This study is still under way. Results are not available in the source record yet.

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?

Contact force (time frame: intraprosedural). 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 NCT06986577, which also lists 3 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 29 Jan 2026.
