Echocardiography and cardiac magnetic resonance imaging characterized the lesion but could not establish its etiology. Surgical excision and pulmonary valve replacement were performed, and histopathological examination demonstrated Congo red\u2013positive amyloid deposition. This case highligts that atypical cardiac manifestations beyond myocardial infiltration can occur in patients with hATTR.
