The 26-year-old media personality, model, and businesswoman Hailey Bieber has been diagnosed with a chronic illness called Grade 5 Patent Foramen Ovale (PFO) after she suffered a transient stroke. Grade 5 PFO is considered the highest grade of Patent Foramen Ovale. In this disease, the patient has a hole in their heart that did not close after birth the way it should.

Due to her health condition, she had to go through a complicated PFO closure procedure. However, the procedure was successful. In a March 2022 Instagram video, Hailey Bieber opened up about her terrible experience with her health condition. In the video, the model said:

"The conclusion was that I had a blood clot that traveled into my heart and instead of — what typically happens if you have a small blood clot is that the heart will filter the blood clot to your lungs and your lungs will absorb it."
