Liam Neeson's 29-year-old son, Daniel Neeson, has shared an update on his health after undergoing surgery for a Bicuspid Aortic Valve (BAV), a congenital heart defect where the aortic valve has two leaflets instead of the normal three. Daniel revealed he had been monitored for the condition for most of his life, but eventually needed 'medical intervention' after experiencing severe left ventricle dilation and aortic enlargement. He thanked his medical team, fiancée, and family for their support during his recovery.

Why it matters

Congenital heart defects like BAV are relatively common, affecting about 2% of the population, but many people are unaware they have the condition. Daniel's openness about his experience highlights the importance of regular cardiac checkups, even for those without known heart issues, in order to proactively monitor and address any developing conditions.
