Mitral Annular Disjunction: Separating the Wheat from the Chaff

may be partly or fully irreversible. Further, it is increasingly recognised that the arrhythmogenic MVP/MAD spectrum is often accompanied by a ventricular myopathy above and beyond the mitral valve apparatus. Such a myopathic substrate obviously remains unaffected by any surgical (or ablative) interventions and may continue to harbour arrhythmic risk. It is worth noting that while transcatheter edge-to-edge repair of the mitral valve reduces regurgitation, it does not correct MAD.
