Challenges in the approach to a patient with aortic stenosis and cardiac amyloidosis with ATTR mutation associated with negative scintigraphy - A case report
Introduction: Cardiac amyloidosis (CA) poses significant diagnostic and therapeutic challenges.In this case report, we detail a patient with CA due to a rare transthyretin (CA-TTR) mutation, manifesting with negative myocardial scintigraphy and requiring genetic testing for diagnosis.The patient also had severe aortic stenosis (AS), necessitating d
