Sienna ‘Sisi’ Leigh Stewart was diagnosed with severe cardiomyopathy when she was just four.

But she began experiencing weakness and was diagnosed with heart failure earlier this year.
The teen, who played in her school volleyball team and was planning to study sonogram tech at college, died nine days after her 18th birthday on 12 June, as reported on Need To Know.
On 23 May, she collapsed at her high school graduation ceremony shortly after it began.
When she regained consciousness, she was so determined to collect her diploma she stayed at the event.
She was the last in her year to do so and received loud cheers and applause from her friends at Hiram High School in Georgia, USA.
Sienna was originally from Erial, New Jersey, but her family moved to Hiram, Georgia, when she was one.
Her obituary said: “[H]er presence alone is contagious, her laugh, smile, her unexpected jokes, and dark humor make you fall off your seat.”
Sienna is survived by her parents and her two older siblings.
