Long Term Evaluation of Cardiac Arrhythmias After Transcatheter Aortic Valve Implantation -The LOCATE Registry
What this study is about
The purpose of the Long term Evaluation of Cardiac Arrhythmias after Transcatheter Aortic Valve Implantation (LOCATE) Registry is to perform long-term ambulatory monitoring of patients with severe aortic stenosis who undergo trans-catheter aortic valve implantation (TAVI) and develop new onset conduction system abnormalities post-procedure that do not require urgent permanent pacemaker (PPM) implantation. The primary objectives of this study are to assess the incidence of late onset heart block necessitating PPM implantation and to evaluate the incidence of new onset atrial fibrillation (AF) following TAVI. This study aims to provide valuable insights into the long-term cardiac health of TAVI patients and inform the development of improved treatment strategies for aortic stenosis patients with conduction system abnormalities.

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
- Patients \> 18 years of age with severe aortic stenosis that undergo TAVI for severe aortic stenosis that develop any one of the following conduction system abnormalities on the immediate post procedural or post operative ECG and have undergone ILR implantation for long-term monitoring of these conditions:
- New left bundle branch block (QRS \>120ms)
- New first degree AV block (PR\>200ms) or worsening of pre-existing first-degree AV block by \>30ms
- New right bundle branch block (QRS\>120ms)
- Intra-procedural 2:1 or higher-grade AV block with spontaneous improvement within 24 hours
Exclusion criteria
- Patients with high grade or complete AV block post TAVI needing urgent pacemakers
- Patient with existing cardiac implantable electronic devices (CIEDs)
- Patients having a particular medical condition that dictates that they cannot tolerate subcutaneous, chronically-inserted device
- Patient is currently pregnant as evidenced by urine positive Beta-HCG. (Urine Beta human chorionic gonadotropin (HCG) will be checked in all females of the reproductive age group).
- Patients not willing to sign the consent, lacks the capacity to sign the consent or revoke the consent after signing will be excluded
Where
- Kansas City, Missouri
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.
