How this study is set up

The points below are drawn from the public registry record for this study. Each one cites the field or sentence it came from. A dash (—) means the record does not state something — not that it is missing or wrong. Many well-run studies, especially small ones, leave some of these blank.

  • Present: Registered before enrolment beganFirst posted 2025-01-15; recorded start 2025-02-06
  • Present: Has a defined primary outcomeA primary outcome measure is listed in the record
  • Present: The primary outcome states a time frameThe primary outcome measure records a time frame
  • Not stated: Whether participants are randomly assigned is not stated in the registry recordNo allocation method is recorded
  • Not stated: A comparison group is not stated in the registry recordThe record describes a single study arm
  • Not stated: Whether the study is blinded is not stated in the registry recordNo masking information is recorded
  • Not stated: An ethics committee is not stated in the registry recordThis registry's ingested record has no ethics-committee field
  • Not stated: Regulatory oversight (such as an IND or IDE) is not stated in the registry recordThis registry's ingested record has no regulatory-authorisation field
  • Not stated: A data monitoring committee is not stated in the registry recordThis registry's ingested record has no data-monitoring-committee fieldA data monitoring committee is not required for many smaller studies, and its absence here is not unusual.
  • Present: No cost to participants is mentioned in the recordChecked the summary, description and eligibility text; no cost-to-participant phrase found
  • Present: Sponsor has 19 other studies in this databaseCounted from the lead sponsor named in the record (Medtronic Cardiovascular)
  • Present: Sponsor has posted results for at least one studyBased on the sponsor’s studies in this database
  • The record lists 1 condition.
  • Lead sponsor type recorded as: industry.

Trial stature

Three independent measures of this study, described from its registry record — not a recommendation about it. A rigorous study by investigators nobody has heard of is better evidence than a weak study led by a famous one. How these are scored.

Methodological rigourEXPLORATORY

An exploratory-stage design for a study of this type, judged from its ClinicalTrials.gov record.

How this score is built

Investigator standingUNKNOWN

We have no verifiable track record for the investigator named on this trial. That is common for early-career investigators and for records held outside ClinicalTrials.gov — it is not a negative signal.

How this score is built
  • Investigator standing0/100

    No investigator recorded in the registry for this trial

These describe the registry record only, and today we hold ClinicalTrials.gov data. Absent fields lower a score, and absence often reflects registration practice rather than study quality. A high-stature trial is not necessarily safer or a better choice for you — enrolling in a large definitive trial can mean a higher chance of receiving placebo, while a small early-phase study may be the only route to a new therapy.

תקציר

The purpose of this study is to generate clinical evidence on valve safety and performance in subjects treated by redo Transcatheter Aortic Valve Replacement (TAVR).

Primary Objectives: * To determine the acute and long-term outcomes of redo TAVR for the treatment of BVF affecting TAVs * To determine the factors which are associated with the acute and long-term outcomes of redo TAVR
