Is this trial a fit for you?

Likely a good fit

Adults (18+ years) undergoing an ablation for atrial arrhythmia using a Boston Scientific ablation system who can provide informed consent and participate in study testing.

Probably not a fit

Patients with implanted cardiac devices or certain valve or defect conditions, or those not undergoing CHORUS IDx-enabled imaging, may not benefit from this study.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This first-in-human prospective study collects human ICE images during planned ablation procedures for atrial arrhythmias to support software development. Participants are adults undergoing ablation with a Boston Scientific commercial system, and consent is obtained prior to any study procedures. The study focuses on acquiring ICE images using the CHORUS IDx system as part of routine clinical workflow at participating centers. Data collection is tied to standard practice and site-specific investigations. No efficacy outcomes are described beyond the imaging data collection for software purposes.

Why it matters

Potential benefit: If successful, the CHORUS IDx system could enable improved imaging during ablation procedures, potentially aiding procedural guidance and planning.

How similar studies have gone: Previous work in novel ICE imaging systems has shown feasibility in procedural imaging, but this specific first-in-human acquisition study is focused on a new device and workflow.

Inclusion Criteria:

1. Subjects who are able and willing to provide written informed consent prior to any study procedure.
2. Subjects who are planned for an ablation procedure for any atrial arrhythmia using any commercially available Boston Scientific Ablation System, per physician's judgement and hospitals' standard practice.
3. Subjects who are willing and able to participate in all testing and assessments associated with this clinical study at an approved clinical investigation center.
4. Subjects whose age is 18 years or above, or who are of legal age to give informed consent specific to state and national law.

Exclusion Criteria:

1. Any of the following cardiac implanted devices

   * Any prosthetic mitral or tricuspid heart valve, such as ring, repairs or clips
   * Atrial septal defect (ASD) occluders including interatrial baffle, closure device, patch, or patent foramen ovale or ASD occluder
2. Subjects with contraindications related to the use of the CHORUS IDx™ System:

   * Subjects with inadequate vascular access
   * Subjects with active systemic infection
   * Subjects with presence of a known intracardiac thrombus in the chamber of use
3. Women who are confirmed to be pregnant or lactating at the time of the Index Procedure
4. Presence of other medical conditions, that, in the investigator's opinion, could limit the subject's ability to participate in the study
5. Subjects who are currently enrolled in another investigational study or registry that would directly interfere with the current study, except when the subject is participating in a mandatory governmental registry, or a purely observational registry with no associated treatments; each instance must be brought to the attention of the Sponsor to determine eligibility
