Liam Neeson's son Daniel Neeson underwent surgery for heart condition

Liam Neeson's son Daniel Neeson revealed on social media that he underwent surgery to treat a severe left ventricle dilation and aortic enlargement.

Liam Neeson's son Daniel Neeson revealed that he underwent surgery to treat a congenital heart defect he has lived with his whole life.

In a March 3 Instagram post, the "Naked Gun" actor's son said he was born with a bicuspid aortic valve (BAV) with only two leaflets instead of the normal three, which can cause valve failure or enlargement of the aorta. Only about 1 to 2 percent of the human population has it, and it is twice as common in males, according to the Cleveland Clinic.

Throughout his life, the 29-year-old has been seeing doctors twice a year for cardiology checkups to monitor his heart, but eventually experienced severe left ventricle dilation and aortic enlargement, he said. While he was hoping not to undergo surgery until later in his life, Daniel said he "drew the early-bird straw."

"Nothing is more empowering than understanding your health, staying on top of your game, and planning ahead. Health is about being proactive, not reactive," he wrote in the post's caption.

"There’s something surreal about realizing that one of your biggest challenges was quietly developing inside you your entire life," he continued. "No dramatic warning. Just science, genetics, and timing."
