La valvola mitrale prolapsa nei sopravvissuti a arresto cardiaco improvviso: coincidenza o relazione causale?

BACKGROUND: Sudden cardiac arrest (SCA) risk stratification in patients with mitral valve prolapse (MVP) may be complicated by other potential causes of arrhythmia. OBJECTIVE: We aimed to characterize SCA survivors with isolated MVP (iMVP) and non-isolated MVP (non-iMVP) and to assess their long-term follow-up. METHODS: This ambispective study included 75 patients with MVP who experienced SCA and were treated in our center between 2009 and 2024. They were divided into 3 groups according to probability of relation between SCA and comorbidities. The control group comprised 112 participants with MVP but without a history of SCA. We analyzed all available electrocardiograms, Holter electrocard
