"A 36-year-old woman presented to the hospital with acute congestive heart failure in keeping with New York Heart Association class III symptoms....Cardiac magnetic resonance imaging suggested that she was a reasonable candidate for a Ross procedure. At operation, she was surprisingly found to have a calcified unicuspid aortic valve with diffuse black discolouration of the cusps." (AlAmodi, 2017).
