The Brugada syndrome is characterized by a distinct ECG pattern consisting of ST segment elevation in the right precordial leads and right bundle branch block, a propensity for life-threatening arrhythmias, and an apparently structurally normal heart. The authors describe the case of a patient with an aborted sudden cardiac death and the typical ECG signs of Brugada syndrome. Nevertheless, magnetic resonance imaging displayed signal enhancement in the left ventricular myocardium. Additionally, histologic examination, in-situ hybridization, and PCR revealed evidence of a locally restricted inflammation due to parvovirus B19. Brugada syndrome is regarded as a primary electrical disease due to dysfunction of distinctive ion channels, but focal myocarditis may serve as a trigger for ventricular arrhythmias in this patient. Further morphologic studies will be helpful to establish the possible role of structural changes in the pathophysiology of this syndrome.

Hereditary heart disease (HHD) is a series of cardiac disorders associated with monogenic or polygenic abnormalities and is one of the leading causes of sudden death, particularly in young adults. The updated European Cardiology guideline for cardiomyopathies provides the first comprehensive summary of genotyping, imaging, and therapy recommendations for inherited cardiomyopathies, but still lacks a comprehensive discussion of research advances and future trends in genetic diagnosis and therapy of HHD. Our research aims to fill this gap.

Brugada syndrome (BrS) is a genetic condition that increases the risk of life-threatening arrhythmias, which can result in sudden cardiac death (SCD). Implantable loop recorders (ILRs) have become a key tool in managing patients with unexplained syncope, and guidelines advise their use in individuals with recurrent, unexplained syncope or palpitations. However, the role of ILRs in inherited arrhythmic conditions like BrS remains a topic of debate.

Structural abnormalities within the right ventricular outflow tract (RVOT) can present similarly to Brugada syndrome. A 34-year-old woman with no medical history presented with polymorphic ventricular tachycardia/ventricular fibrillation cardiac arrest and initial electrocardiogram showed type I Brugada pattern. Cardiac magnetic resonance imaging revealed prominent tissue thickening at the RVOT with late gadolinium enhancement.
