Plain-language summary
Mitral regurgitation (MR) is a prevalent valvular heart pathology. Indications for surgery include symptoms, impaired left ventricular function or enlarging dimensions, new onset atrial fibrillation, pulmonary hypertension, asymptomatic status with a high likelihood of success.
Asymptomatic severe primary MR can be initially monitored without impairing long term survival. However, significant symptoms or impairment of left ventricular function is associated with worse prognosis due to long term heart failure. Some physicians wait for early symptoms before referring for surgery and this is reflected by a great variation in referral patterns, but symptomatic status is subjective and difficult to assess. Nearly all of the surgical indications are based on expert opinion rather than significant evidence base.
The primary aim of this project is to improve the current guidelines for surgery for primary MR by finding an objective marker of functional capacity which correlates with surrogates of prognosis and detects early decline, but returns to normal after surgery.

AI-rewrites the medical criteria so a patient or caregiver can understand them. Always confirm with the trial site.
Inclusion Criteria:
Patients listed for surgery for severe primary mitral regurgitation +/- concomitant coronary artery bypass grafting for bystander disease +/- tricuspid valve surgery +/- atrial fibrillation surgery.
Exclusion Criteria:
Secondary mitral regurgitation. Significant history of ischaemic heart disease eg. angina. Age \<18 years or \>85 years. Critical preoperative status with multi-organ dysfunction. Emergency cardiac surgical intervention. Pregnancy. Unable to give informed consent or unwilling to participate in research. Patients with definite contraindication for MRI would be excluded from the cardiac MRI element of the study.
Patients we are unable to take adequate biopsies due to technical difficulties would be excluded from the myocardial biopsy element of the study.
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.
