Thai Princess Bajrakitiyabha has died after being in a coma for over three years, the Royal Household announced. The 47-year-old princess collapsed while walking her dogs in December 2022. Medical professionals determined the collapse was due to a severe cardiac arrhythmia stemming from a mycoplasma infection affecting her heart. She was the eldest daughter of King Maha Vajiralongkorn and was considered a potential heir to the throne. The palace statement confirmed her passing but did not provide details regarding funeral arrangements. Her condition had been closely monitored by the public and the royal family since the incident.
