Intracardiac Thrombosis: An Uncommon Manifestation of Behçet's Disease.

Behçet's disease is a chronic multisystemic vasculitis of unknown etiology that evolves in relapses and remissions with a predominance of cutaneous and ocular lesions. It is more frequent in young adults, with a predominantly male population from the Mediterranean and Middle East. Cardiac involvement is rare (1 to 6%) but represents one of the most serious complications that can affect the three tunics of the heart. Cardiac thrombus is uncommon, its diagnosis relies mainly on echocardiography, and the development of the empirical treatment is based on immunosuppressive therapy and anticoagulation depending on the case. We report the case of a 21-year-old man admitted for a 2-month history of fever, loss of weight, and body condition in association with an intracardiac thrombus in the context of Behçet's disease. Intracardiac thrombus is a rare manifestation of Behçet's disease; the diagnosis must be made quickly in order to allow early management.

Biventricular arrhythmogenic cardiomyopathy diagnosed in a young patient: A case report with literature review.

Arrhythmogenic cardiomyopathy is a genetic heart muscle disease that typically affects the right ventricle. However, 2 other phenotypes affecting the left ventricle were recently discovered. Here, we report the case of an 18-year-old patient with biventricular arrhythmogenic cardiomyopathy, highlighting the challenges encountered in establishing this diagnosis. Diagnostic criteria for the left-sided phenotypic variants of arrhythmogenic cardiomyopathy were only introduced in 2020 by an international expert consensus document, known as the "Padua criteria," they are divided in 6 categories with an emphasis on morpho-functional ventricular abnormalities and structural myocardial tissue alterations to diagnose biventricular arrhythmogenic cardiomyopathy.
