Prospective Multicentre Observational Registry of Peri-procedural Anaesthesia, Sedation and Related Medication Exposure in Patients With Brugada Syndrome
Spain200 participantsStarted 2026-07-20
Plain-language summary
The goal of this observational study is to evaluate the perioperative risk of malignant ventricular arrhythmias in adult patients diagnosed with Brugada Syndrome undergoing anaesthetic procedures. Brugada Syndrome is a rare inherited cardiac condition associated with an increased risk of life-threatening arrhythmias, and perioperative management remains challenging due to limited high-quality evidence.
The main questions it aims to answer are:
* What is the incidence of malignant ventricular arrhythmias during anaesthesia and up to 30 days after the procedure?
* Are anaesthetic drugs traditionally considered "non-recommended" associated with an increased risk of perioperative arrhythmic events?
Researchers will also explore the relative contribution of anaesthetic drugs versus perioperative physiological factors (e.g., haemodynamic changes, fever, bradycardia) in triggering arrhythmias.
Participants will:
* Undergo anaesthetic procedures (general, locoregional, or sedation) as part of routine clinical care
* Have clinical data collected prospectively from electronic medical records during the perioperative period
* Be followed for 30 days after the procedure to assess outcomes, including arrhythmias, complications, ICU admission, and mortality
This is a multicentre, prospective observational registry, and no additional interventions or changes to standard clinical practice will be performed.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Patients should match all the inclusion criteria to be entered for data collection:
* Documented type 1 Brugada ECG pattern (spontaneous, fever-related, or induced by sodium-channel blocker challenge/other recognised provocation test) with a diagnosis considered compatible with Brugada syndrome by the treating cardiology team.
* Undergoing general anaesthesia, monitored sedation, loco-regional anaesthesia for any surgical, diagnostic, interventional, obstetric or other non-surgical procedure (including epidural analgesia for labour and sedation for endoscopy).
Patients with one or more exclusion criteria will not be included for data collection and analysis:
* No documented type 1 Brugada ECG pattern, uncertain diagnosis without sufficient supporting data.
* Refusal to participate in the study.
Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
