Arrhythmogenic right ventricular dysplasia is a hereditary cardiomyopathy - a common cause of sudden cardiac death in children and young adults. Loeys-Dietz syndrome is an ultra-rare connective tissue disorder characterized by aneurysms of the aorta and other large arteries, arterial tortuosity, and joint hypermobility and is associated with pathogenic variants in genes encoding protein components TGF-β pathway.
