Real-world Experience of Catheter Ablation for the Treatment of Arrhythmias
(REAL Registry)
What this study is about
The primary purpose of this Registry is to assess procedural safety and long-term effectiveness of catheter ablations in the treatment of subjects with PAF, PsAF, and VA. The Registry will utilize real world clinical data obtained from the use of commercially available CARTO™ technologies under the authority of a health care practitioner within a legitimate practitioner-subject relationship.
View original scientific description
The primary purpose of this Registry is to assess procedural safety and long-term effectiveness of catheter ablations in the treatment of subjects with PAF, PsAF, and VA. The Registry will utilize real world clinical data obtained from the use of commercially available CARTO™ technologies under the authority of a health care practitioner within a legitimate practitioner-subject relationship. Data from the registry will be used to assess clinical outcomes, including procedural efficiency, safety, and long-term effectiveness of catheter ablation with novel technologies for arrhythmia patients.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- Symptomatic PAF (AF episode terminate spontaneously within 7 days) or PsAF (AF sustained beyond 7 days, but less than 365 days) subjects who, in the opinion of the investigator, are candidates for catheter ablation.
- \>18 years of age.
- Will be treated with Biosense Webster Inc. ablation technologies
- All AF ablations performed with BWI catheters are included. This includes repeat ablations where the index procedure was performed with a non-BWI catheter.
- Able and willing to participate in baseline and follow up evaluations
- Willing and able to provide informed consent, if applicable.
Exclusion criteria
- Enrolled in an investigational drug or device clinical trial, or any trial that dictates the treatment plan
- Long-standing persistent AF (AF greater than one year)
- In the opinion of the investigator, any known contraindication to an ablation procedure CORE VA Cohort Inclusion Criteria:
- Documented ventricular arrhythmia appropriate for catheter ablation.
- \>18 years of age.

- Willing and able to provide informed consent, if applicable. Exclusion Criteria:
- Enrolled in an investigational drug or device clinical trial, or any trial that dictates the treatment plan.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
