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.
