Cardiac magnetic resonance imaging after ventricular tachyarrhythmias increases diagnostic precision and reduces the need for family screening for inherited cardiac disease

摘要

Aims Guidelines recommend evaluation of family members of sudden cardiac death victims. However, initiation of cascade screening in families with uncertain diagnoses is not cost-effective and may cause unnecessary concern. For these reasons, we set out to assess to what extent cardiac magnetic resonance imaging (CMR) would increase the diagnostic precision and thereby possibly change the indication for family screening in patients with ventricular tachyarrhythmias.
