Mitral valve prolapse in sudden cardiac arrest survivors - coincidence or causal relationship?

Background: Sudden cardiac arrest (SCA) risk stratification in patients with mitral valve prolapse (MVP) may be complicated by other potential causes of arrhythmia.

Objectives: We aimed to characterize SCA survivors with isolated (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 2009-2024.

Troponin T Assessment Allows for Identification of Mutation Carriers among Young Relatives of Patients with -Related Dilated Cardiomyopathy.

-related dilated cardiomyopathy (-DCM) caused by mutations in the lamin A/C gene () is one of the most common forms of hereditary DCM. Due to the high risk of mutation transmission to offspring and the high incidence of ventricular arrhythmia and sudden death even before the onset of heart failure symptoms, it is very important to identify -mutation carriers. However, many relatives of -DCM patients do not report to specialized centers for clinical or genetic screening.
