Overview
- News of Lucia Sisic’s death was first shared by a family friend and confirmed by the Miss-Austria-Organisation on social media on Tuesday, prompting widespread tributes.
- Sisic lived with a congenital heart valve defect and underwent seven heart operations during her life, a history she discussed publicly to encourage others.
- A 2017 surgery required resuscitation and led to months in hospital and nerve damage, and her most recent cardiac procedure took place in winter 2025 when she said she hoped for a multi-year break from operations.
- Sisic won Miss Vienna and then Miss Austria in 2024 and remained the reigning titleholder because no national Miss-Austria contests were held in 2025 or 2026 due to a lack of sponsors.
- Authorities and family have not released a cause of death and it is not known whether her passing is related to her heart condition, with current coverage relying on social posts and past interviews.
