Looking at 6-year-old Brodie Cresswell running around the house, he seems like any other boisterous boy.
But under his shirt an impressive scar shows a glimpse of the rollercoaster ride that Brodie and his parents, Michelle and Philip, have been on over the past six years.
When their long-awaited only child was born two months premature, Mrs Cresswell said the couple thought that would be the toughest thing to endure.
Then, when he was 2, he was admitted to Rotorua Hospital with high temperatures. The cause turned out to be an infection, but as part of the "top-to-toe examination" doctors ordered, a shadow was found on his lung.
It turned out to be an extremely rare heart condition called Scimitar syndrome.
