The Asia-Pacific Mitral & Tricuspid Valve-in-Valve/Valve-in-Ring Registry (AP ViV)

December 16, 2025 updated by: Dr So Chak Yu kent, Prince of Wales Hospital, Shatin, Hong Kong
A significant number of patients with severe mitral and tricuspid valve disease have been previously treated with either valve repair with annuloplasty rings or valve replacement with bioprosthetic/mechanical valves. Over time, these bioprosthetic valves and rings may fail resulting in recurrence of the valvular disease. The technical aspects of a re-do operation are complex and these patients are often times at high risk for repeat open surgery. The emergence of transcatheter options may provide a safer and less invasive alternative to open surgery. Majority of the data currently exist for Western cohorts with limited longer-term outcomes. Data on this therapy is particularly lacking in the Asia-Pacific region, especially important in the light of known differences in body habitus and size.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

Sampling Method

Non-Probability Sample

Inclusion Criteria:

  1. Age ≥ 21
  2. Had at least one documented Mitral valve-in-valve/valve-in-ring procedure done during the period of 1 Jan 2023 to current date. (Retrospective) OR Planned to undergo a Mitral valve-in-valve/valve-in-ring procedure. (Prospective) OR Had at least one documented Tricuspid valve-in-valve/valve-in-ring procedure done during the period of 1 Jan 2023 to current date. (Retrospective) OR Planned to undergo a Tricuspid valve-in-valve/valve-in-ring procedure. (Prospective)

Exclusion Criteria:

  1. Active endocarditis
  2. Any other conditions which investigator deems unsuitable for participation.

Cohorts and Interventions

Group / Cohort

Group / Cohort

A group or subgroup of participants in an observational study that is assessed for biomedical or health outcomes.
Prospective

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
All-cause mortality
Time Frame: 10 years
Rate of All-cause mortality in enrolled patients
10 years

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Procedural technical success rate
Time Frame: Immediately after operation
Rate of Procedural technical success (defined per Mitral Valve Academic Research Consortium (MVARC) criteria at exit from the hybrid suite as patient alive with successful access, delivery, and retrieval of the device delivery system, successful deployment and correct position of the first intended device, and freedom from emergency surgery or reintervention associated with the device or access procedure)

Primary Completion (Estimated)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date. For clinical studies with more than one primary outcome measure with different completion dates, this term refers to the date on which data collection is completed for all the primary outcome measures. The "anticipated" primary completion date is the date that the researchers think will be the primary completion date for the study.
