Sisic had lived with a congenital heart valve defect since birth and underwent seven heart procedures during her life.
Her death came as a shock to the Austrian pageant community and those who knew her personally. She had continued to pursue her interests and public career despite years of serious health challenges and had spoken openly about her medical journey.
Who Was Lucia Sisic?
Lucia Sisic was an Austrian beauty queen from Vienna who rose to prominence through the Miss Vienna and Miss Austria competitions in 2024.
She first won the Miss Vienna 2024 title before going on to become Miss Austria 2024. Because no new Miss Austria competition was held after her victory, Sisic remained the country’s reigning titleholder until her death.
She was 22 when she died.

Early Life and Family Background
Sisic was from Vienna, while her family had roots in Bosnia and Herzegovina.
Reports about her family background have linked her parents to the Brčko area of Bosnia and Herzegovina. Her Bosnian heritage remained an important part of her connection to the country, and she visited Bosnia during the summer shortly before her death.
Despite growing up with a serious congenital heart condition, Sisic developed a strong and independent personality.
Lucia Sisic’s Health Struggles
One of the defining parts of Sisic’s life was her long battle with a congenital heart valve defect.
The condition affected her childhood and placed restrictions on the physical activities she could participate in. She previously spoke about being unable to take part in some school sports activities because of medical advice.
Her health journey included seven heart procedures.
Sisic also revealed that some moments during her treatment had been extremely serious. Despite those experiences, she continued to describe herself as grateful for the opportunity to live a full life.
In a message shared after one of her procedures, she thanked the pediatric cardiology specialists and doctors who had repeatedly helped save her life.
Miss Vienna 2024
Sisic’s entry into beauty pageants was not necessarily a long-planned career move.
According to reports from the time, she registered for the Miss Vienna competition at relatively short notice. Her personal motto during the competition was “Be Yourself.”
She ultimately won the Miss Vienna 2024 crown.
The competition included several presentation and fashion rounds, and her victory gave her an opportunity to represent Vienna at a larger national level.
Winning Miss Austria 2024
Later in 2024, Sisic won the Miss Austria 2024 title.
The competition included fashion-focused elements, including a colorful “dopamine dressing” theme. Her victory established her as one of Austria’s best-known young pageant figures.
Her Miss Austria reign became unusual because the competition was not held again in the following period. As a result, Sisic remained the reigning Miss Austria through 2025 and into 2026.
Vienna Opera Ball Appearance
After winning Miss Vienna, Sisic also gained access to some of Vienna’s most prominent social and cultural events.
She attended the Vienna Opera Ball with Austrian businessman Richard Lugner. The appearance became one of the notable public moments of her early pageant career.
Lucia Sisic’s Final Heart Operation
Sisic underwent her seventh heart procedure in late 2025.
After the operation, she expressed hope that she would finally be able to take a break from surgeries for several years.
She wrote that she was extremely happy to have completed her seventh procedure and hoped it would give her a longer period without another operation.
The post reflected the optimism that she continued to show despite her long medical history.
Her Final Months
Sisic remained active on social media during the months before her death.
She shared photographs from her life and travels, including a trip to Bosnia and Herzegovina. One of her recent posts featured her wearing a gold dress under the caption “Golden moments.”
Her social-media presence frequently reflected positivity and resilience.
Her sudden death therefore came as an especially painful shock to people who had followed her journey.
Lucia Sisic’s Death
Lucia Sisic died in September 2026 at the age of 22.
As of the latest reports, her exact cause of death had not been publicly confirmed. Although she had lived with a congenital heart defect and undergone seven heart procedures, reports have not established that her underlying condition was officially determined to be the cause of death.
That distinction is important because her medical history should not be presented as a confirmed explanation for her death without an official statement.
Tributes to Lucia Sisic
News of Sisic’s death prompted emotional tributes from people within the Austrian pageant community.
Christopher Dengg, Mister Austria, said he was shocked by her death and would miss her greatly. He described Sisic as being like a sister to him, particularly during the period when they held their national titles together.
Mission Austria CEO Kerstin Rigger and her husband Jörg also paid tribute to Sisic, remembering her as a wonderful young woman and saying that she would remain part of their family.
Those close to her remembered not only her beauty but also her warmth, determination and ability to remain positive despite years of medical difficulties.
Lucia Sisic’s Legacy
Sisic’s story extended beyond her beauty-pageant titles.
Her journey from a child living with a congenital heart condition to Miss Vienna 2024 and Miss Austria 2024 made her story unusual within Austrian pageantry.
She spent much of her young life undergoing medical treatment, yet continued to pursue opportunities that allowed her to represent herself publicly and professionally.
Her death at only 22 brought renewed attention to the young woman behind the crown and to the resilience she demonstrated throughout her life.
