Liam Neeson's son Daniel Neeson recently underwent surgery to address a left ventricle dilation and aortic enlargement caused by a rare condition he was born with: a bicuspid aortic valve. Daniel, whom Neeson shared with his late wife Natasha Richardson, detailed the experience on Instagram, emphasizing the importance of staying up-to-date with one's health.

Why it matters

Daniel's case highlights the need for regular cardiac screenings, even for those without known heart defects. Bicuspid aortic valve, which affects about 2% of the population, can often go undetected until it starts causing complications later in life.

The details

Daniel was aware of his condition from birth and had biannual cardiology checkups to monitor his heart. However, he eventually started experiencing severe left ventricle dilation and aortic enlargement, leading to the need for surgery. The procedure was performed at NewYork-Presbyterian's Weill Cornell Medical Center.
