A Rare Presentation of Systemic Sclerosis

Systemic sclerosis (SSc) is a persistent autoimmune disorder. While it commonly impacts the cardiac valves, particularly the mitral valve, involvement of the aortic valve has been seldom documented. We report a case of a 47-year-old male with a history of progressive SSc who displayed complications related to cardiac issues, which were verified through a left atrial appendage biopsy revealing thickening due to fibrosis. This cardiac involvement led to a condition necessitating the replacement of the aortic valve due to aortic regurgitation. This instance underscores the importance of identifying this uncommon association, enabling the delivery of appropriate patient treatment, and reducing complications linked to the underlying condition.
