Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Adult males and females aged 20 years or above
  • Target of Thoracic Surgery for TR and patients above the severe level on the criteria presented in the Classification of TR Grade based on echocardiogram, among those with TR, for whom a surgical treatment has been decided
  • An individual who voluntarily agreed to the participation in the clinical trial and signed the written consent
  • An individual who is able to understand and comply with the instructions and who can participate in the period before the clinical trial

Exclusion criteria

Exclusion Criteria:

  • Uncontrolled hyperthyroidism
  • A recent formation of soft blood clot or embolic material
  • Uncorrected coagulopathy
  • Prohibition of anticoagulant agents
  • Previous insertion of a device such as an Implantable Cardioverter Defibrillator (ICD) or a pacemaker
  • Presence of malignant tumor or benign tumor such as myxoma in the heart
  • Presence of a symptom of active infection
  • Chronic pulmonary disease
  • Congenital tricuspid valve insufficiency
  • Pregnant or lactating mother, or a female patient planning pregnancy during the period of clinical trial, or a female not using an approved with the possibility of pregnancy
  • Participation in another clinical trial 30 days prior to the screening
  • In addition, anyone showing a clinical finding deemed to be unsuitable for the clinical trial by the Principal Investigator or the Investigator
Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

What researchers measure

Primary outcomes

  1. change of tricuspid regurgitation grade (1)

    check the success of surgery /measure the size of the TR area

    Time frame: immediately after the procedure

  2. change of tricuspid regurgitation grade (2)

    examine the changes in the severity of tricuspid valve insufficiency with Echocardiogram

    Time frame: immediately after the procedure

Secondary outcomes

  1. change of tricuspid regurgitation valve hemodynamics

    examine the changes in the severity of tricuspid valve insufficiency with Echocardiogram

    Time frame: within 24 h of insertion

  2. evaluate the efficacy based on the function of early diagnosis (1)

    examine tricuspid regurgitation intolerance

    Time frame: within 24 h of insertion

  3. evaluate the efficacy based on the function of early diagnosis (2)

    evaluate the technical success rate of the implantation and the technical feasibility of 'Pivot Balloon'

    Time frame: within 24 h of insertion

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Jul 2021 to primary completion in Jan 2023, 18 months.

Of 55 industry-sponsored interventional studies with no phase under Tricuspid Valve Insufficiency, half reached primary completion within 38 months of starting (the median), counting those still running; a quarter within 27 and three quarters within 70. This study's 18 months is below that.

Counting every sponsor, half of 86 studies reached it within 38 months; a quarter within 23 and three quarters within 58.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Apr 16, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
