Randomized Trial of Transcatheter Valve-in-Valve vs Redo Surgery for Bioprosthetic Mitral Dysfunction
Brazil150 participantsStarted 2020-02-17
Plain-language summary
Transcatheter valve-in-valve implantation has emerged as a valid alternative to redo surgery for patients with surgical bioprosthetic dysfunction. Nowadays, transcatheter, transeptal mitral valve-in-valve replacement (TsMViV) has been adopted in many centers worldwide. Some studies report low rates of periprocedural morbidity and mortality and favorable hemodynamic parameters of valve performance. However, medium and long-term data on TsMViV as compared to redo surgical mitral valve replacement (rSMVR) is not yet established. Studies of cost-effectiveness and cost-utility comparing both strategies were also not reported. In particular, late prosthesis durability and hemodynamic performance after TsMViV are largely unknown and need to be elucidated before widely indicated, especially among younger and low-risk surgical candidates with failed mitral bioprostheses.

* Severe mitral bioprosthetic dysfunction (stenosis, regurgitation, mixed) defined by echocardiography;
* Heart team (including cardiac surgeon) agree on eligibility including assessment that transeptal, transcatheter mitral valve replacement (TsMVR) and redo surgical mitral valve replacement (rSMVR) are appropriate;
* The study patient or the study patient's legal representative informed of the nature of the study, agreed to its provisions and provided written informed consent as approved by the Institutional Review Board (IRB) center;

Questions worth asking your doctor
Bring these to your next appointment. They're a starting point for a shared conversation — not a sign you qualify or a recommendation to enrol.
1Based on my diagnosis and history, is this trial worth exploring for me — or is there a standard treatment we should try first?
2What does this trial's phase tell us about how much is already known about its safety and benefit?
3What would taking part actually involve for me — visits, tests, time, and travel?
4What are the known and possible risks or side effects I should weigh, and how would they be monitored?
5If this trial isn't the right fit, what other options or trials would you suggest I look into?
Generated to help you prepare — always confirm anything about your own eligibility and care with the study team and your doctor.
Questions for the trial coordinator
The trial coordinator is the person who runs the study day to day. These cover the practical side — logistics, costs, and what taking part would actually mean for your life. The study team confirms whether you meet the criteria; these are questions to ask, not a sign you qualify.
1What does taking part actually involve week to week — how many visits, where, and how long does each one take?
2What costs are covered by the study, and what might I have to pay for myself, including travel, parking, or time off work?
3What happens during screening, and what happens if the study team confirms I don't meet the criteria after those tests?
4Who pays for the scans, blood work, and other tests the trial requires — the study, my insurance, or me?
5How will being in the trial affect my regular care, and will my own doctor stay informed and involved?
6Can I leave the trial at any point if I change my mind, and what would happen to my care if I do?
A starting point for the conversation — always confirm anything about your own eligibility, costs, and care with the study team and your doctor.
