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 2021-12-29; recorded start 2022-06-20
  • 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: Participants are not randomly assignedAllocation is recorded as non-randomised
  • Present: Has a comparison groupThe record lists a placebo or comparator arm, or more than one study arm
  • Not stated: Open label (no blinding)Masking is recorded as none (open label)
  • 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 47 other studies in this databaseCounted from the lead sponsor named in the record (Edwards Lifesciences)
  • 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 rigourMODERATE

A moderately rigorous design for a study of this type, judged from its ClinicalTrials.gov record.

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 objective of this study is to establish the safety and effectiveness of the Edwards SAPIEN X4/X4S Transcatheter Heart Valve (THV) in subjects with symptomatic, severe, calcific aortic stenosis (AS).

This is a prospective, single arm, multicenter study. Subjects with bicuspid aortic valve morphology will be enrolled in a separate registry.

Inclusion Criteria: 1. Severe, calcific AS 2. Native aortic annulus size suitable for SAPIEN X4 THV 3. NYHA functional class ≥ II 4. The subject has been informed of the nature of the study, agrees to its provisions and has provided written informed consent. Exclusion Criteria: 1. Anatomical characteristics that would preclude safe femoral placement of the introducer sheath or safe passage of the delivery system 2. Aortic valve is unicuspid, bicuspid or non-calcified 3. Pre-existing mechanical or bioprosthetic valve in any position 4. Severe aortic regurgitation (\> 3+) 5. Severe mitral regurgitation (\> 3+) or ≥ moderate mitral stenosis 6. Need for mitral, tricuspid or pulmonic valve intervention within the next 12 months 7. Left ventricular ejection fraction \< 20% 8. Cardiac imaging evidence of intracardiac mass, thrombus or vegetation 9. Left ventricular outflow tract calcification that would increase the risk of annular rupture or significant PVL after THV implantation 10. Increased risk of coronary artery obstruction after THV implantation 11. Myocardial infarction within 30 days prior to the study procedure 12. Hypertrophic cardiomyopathy with subvalvular obstruction 13. Subjects with planned concomitant ablation for atrial fibrillation 14. Complex coronary artery disease (CAD) that cannot be optimally treated by percutaneous coronary intervention (PCI) 15. Any surgical or transcatheter procedure within 30 days prior to the study procedure (unless part of planned strategy for treatment of CAD). Implantation of a permanent pacemaker or implantable cardioverter defibrillator (ICD) is not considered an exclusion. 16. Any planned surgical or transcatheter intervention to be performed within 30 days following the study procedure (unless part of planned strategy for treatment of CAD) 17.

מדדי תוצאה

  1. מדד תוצאה ראשוני

    Non-hierarchical composite of death and stroke

    The number of patients that died or had a stroke

    מסגרת זמן 1 year

  2. מדד תוצאה משני

    Favorable outcome per VARC-3: Composite of 1) alive, 2) Kansas City Cardiomyopathy Questionnaire (KCCQ) score ≥ 60, and 3) KCCQ score decrease ≤10 points from baseline

    The number of patients that met all of these criteria. The KCCQ is a 23-item, self-administered instrument that quantifies physical function, symptoms (frequency, severity and recent change), social function, self-efficacy and knowledge, and quality of life. An overall summary score can be derived from the physical function, symptom (frequency and severity), social function and quality of life domains. Scores are transformed to a range of 0-100, in which higher scores reflect better health status.

    מסגרת זמן 1 year

  3. מדד תוצאה משני

    Paravalvular leak

    Paravalvular leak will be categorized as None, Trace, Mild, Mild-Moderate, Moderate, Moderate-Severe, or Severe

  4. מדד תוצאה משני

    New permanent pacemaker implantation

    The number of patients with this event
