This subgroup is referred to as AMVP (arrhythmic MVP) and was recently defined using the following criteria: (1) Presence of MVP), (2) Ventricular arrhythmia that is either frequent (≥5% total premature ventricular contraction (PVC) burden on Holter) or complex (non-sustained ventricular tachycardia (nsVT), ventricular tachycardia (VT), or ventricular fibrillation (VF)), and (3) The absence of any other well-defined arrhythmic substrate.\n\nCurrently, diagnosis is often based on repeated 24-hour Holter monitoring. However, the ventricular arrhythmia burden varies from day-to-day and long-term rhythm monitoring has shown in other pathologies to increase the diagnostic yield with up to 200% (from 22.5% on 24h to 75.3% on 14 days).\n\nThis pilot study aims to study the diagnostic yield of long-term rhythm monitoring in patients with MVP as well as the day-to-day variability of ventricular arrhythmias to facilitate power calculation for a future large-scale prospective registry.",[65,66],"Mitral Valve Prolapse","Ventricular Arrythmia","2026-04-28",{"date":69,"type":70},"2026-05-05","ACTUAL",{"date":72,"type":70},"2024-05-01",{"date":74,"type":59},"2026-06",{"name":5,"class":6},1]
