Can a new risk score predict deadly heart rhythms in mitral valve prolapse?
NCT ID NCT07830888
First seen Sep 21, 2026 · Last updated Sep 21, 2026
Summary
Mitral valve prolapse is common and usually harmless, but a small group of patients develop dangerous heart rhythms that can cause sudden cardiac arrest. Researchers at Oslo University Hospital are building and testing a risk prediction model that combines clinical exams, electrocardiograms, heart imaging and cardiac MRI to estimate each patient's individual risk. The study follows about 500 people with mitral valve prolapse and some arrhythmia burden for at least six months to see who develops severe ventricular arrhythmias. The goal is to help doctors decide who might benefit from closer monitoring or an implantable defibrillator.
What this could mean
Our plain-language read of the trial. This is informational only, not medical advice or a prediction.
- What this could lead to
- If the model works, doctors could better identify which people with mitral valve prolapse face dangerous heart rhythms and may need closer monitoring or a defibrillator.
- What could go wrong
- This is an observational study that builds a statistical model, not a treatment. The model may not predict accurately in other hospitals or patient groups, and it cannot prove that acting on its predictions saves lives.

Copied word for word from the study's registry entry, so the wording is the study team's rather than ours.
Inclusion Criteria: 1. MVP according to the ESC definition AND 2. Arrhythmic burden of: * A total PVC burden ≥ 0,5 % per day OR * Documentation of NSVT on any modality OR * More severe ventricular arrhythmias (sustained ventricular tachycardia, ventricular fibrillation, aborted cardiac arrest) that occurred \>1 month after the beginning of follow up. AND 3. Follow up \>6 months Exclusion Criteria: * 1\. VT/VF as the initial presentation without prior cardiac evaluation (ECG, echo, Holter) 2. History of myocardial infarction 3. Obstructive coronary diseases - ≥50 % stenosis that was not treated 4. History of coronary artery bypass surgery 5. Significant valve disease other than MVP - rheumatic heart disease, severe aortic stenosis 6. LGE suggestive of probable myocarditis as the etiology. 7. Primary inherited arrhythmia - Brugada syndrome, short QT, long QT, CPVT 8. Carrier of disease causing mutation known to be associated with arrhythmia even when phenotype is negative (e.g. Lamin A/C) 9. Sustained ventricular arrhythmia clearly caused by a reversable cause
