Outcome Measures
Primary Outcomes (1)
Composite endpoint: cardiovascular mortality, congestive heart failure and hospitalization for nonfatal cardiovascular events
The primary outcome is defined as 'time to first event'. It concerns time to first event of the composite endpoint of cardiovascular mortality, congestive heart failure, non-fatal cardiovascular events requiring hospitalization, defined as: stroke/cerebrovascular accident (CVA), atrial fibrillation (permanent or requiring hospitalization) and/or reoperation after elective MV surgery.

Interventions
In case of watchful waiting a conservative treatment is performed, based on close monitoring of the patient for clear signs of deterioration that triggers facilitated surgery before left ventricular dysfunction is present.
Patients in the group of early mitral valve repair will be operated by way of routine mitral valve repair procedures in specialized centres.
Eligibility Criteria
You may qualify if:
- Asymptomatic
- Severe organic mitral valve regurgitation.
- Preserved left ventricular function (left ventricular ejection fraction \>60% and left ventricular end-systolic dimension ≤45 mm)
- The likelihood of MV repair should be more than 90% determined by the local heart team with a cardiologist and cardiothoracic surgeon
You may not qualify if:
- Pulmonary hypertension (\>50 mmHg at rest)
- Atrial fibrillation
- Physical inability as determined by the heart team to undergo surgery
- Other life-threatening morbidity
- Higher expected surgical risks in advance, according to the dedicated heart team
- Moderate to severe kidney disease (eGFR less than 30 mL/min)
- Flail leaflet together with a left ventricular end systolic diameter (LVESD) \>40 mm
