ATTRwt Cardiac Amyloidosis and Aortic Regurgitation in a Patient with Acute Myelomonocytic Leukemia: an Unusual Combination
DOI: 10.36660/abcimg.20240127i
Introduction
Systemic amyloidosis is a relatively rare multisystem disease caused by the deposition of misfolded protein in various tissues and organs. Cardiac amyloidosis (CA) is recognized as an underlying cause of left ventricular wall thickening, heart failure, and arrhythmia with variable clinical presentation. The clinical diagnosis of cardiac involvement in amyloidosis is challenging, requiring a patient-centered diagnostic work-up that ensures an appropriate diagnosis.,
Although amyloidosis has been associated with multiple malignant disorders, its association with leukemia is rather uncommon.– Also, there is a relationship between CA and valvular heart disease, particularly aortic stenosis (AS). The association of ATTRwt CA and aortic regurgitation (AR) in a patient with acute myelomonocytic leukemia (MML) is unique and has not been described so far.
