Arrhythmic Mitral Valve Prolapse: New Menaces of the Known Disease

Mitral valve prolapse (MVP) has long been the subject of intense discussions regarding prognosis and follow-up tactics. In most cases, this condition a benign prognosis. However, recent autopsy studies have shown risks developing sudden cardiac death (SCD) in some subgroups patients who clinical phenomenon. The proposed literature review uses population with MVP highest probability life-threatening ventricular tachyarrhythmias. Patients presence complex changes, including bicuspid MVP, negative T waves inferior lateral leads on standard 12-lead electrocardiogram (ECG), special anatomical phenomenon called mitral annular disjunction (MAD), are at high risk ectopias VSS. A reflection SCD such is increase ectopy according to Holter monitoring. MAD phenomenon, which separation line attachment posterior leaflet from basal wall segment towards atrial wall, determines form so-called arrhythmogenic MVP. Hence, cases aforementioned ar- rhythmic signs must be given particular attention annual ECG control, monitoring echocardiographic examination heart reduce tachyarrhythmias development.
