Ed Helms reveals he had open heart surgery when he was fourteen!

Los Angeles - Ed Helms had open heart surgery as a teenager.

The Vacation star has revealed he suffered from a severe heart murmur as a young boy and had to undergo the serious operation to correct the problem.

When asked for 25 surprising facts about himself, he told Us Weekly magazine: "I have a nice, long scar on my chest from open heart surgery when I was 14."

The 41-year-old actor previously insisted everything was"fine" following the surgery.

He said at the time: "I had open-heart surgery [to repair a murmur] when I was in the seventh grade.

"Everything is fine now. I have a 10-inch zipper scar right down my sternum."

It is not the first time Ed has felt uneasy in a hospital as he also revealed he nearly suffered a panic attack whilst in a magnetic resonance imaging (MRI) machine.

He shared: "I almost had a panic attack inside an MRI machine but managed to keep it together."

Despite the setback, he was a keen sportsman at school, something which has continued on with him into later life.

He said: "My shoulders are very loose from competitive swimming in high school and college ...

"I will run for hours in a game of soccer or basketball, but I can't stand jogging."
