London: A six-year-old British boy is recovering well after becoming the first person in the world to have a valve in his heart widened using an MRI scan rather than X-ray imaging.Jack Walborn was born with the heart condition pulmonary valve stenosis, a condition in which the outflow of blood from the right side of the heart is obstructed, restricting flow to the lungs.Surgeons decided he needed an operation called a valvuloplasty to widen the valve and increase blood flow.This is done by inserting a catheter into a blood vessel in the arm or groin and guiding it to the heart.At the tip of the catheter is a balloon, which is gently inflated to widen the narrowed valve.X-ray imaging is usually used to track the progress of the catheter through the body.
"At first I was unsure about allowing Jack to be the first person to have this operation, but once I had spoken to the doctors I felt much more at ease as I knew he was in safe hands," the BBC quoted Jacks``s mother as saying."His surgery was a great success and within an hour of coming out of theatre he was running around and back to being his lively self," she added.Judy O``Sullivan, a senior cardiac nurse at the British Heart Foundation, said: "Technology is advancing at a great pace and in the future we hope that many more patients will benefit from the use of MRI scans rather than X-ray imaging, as MRI avoids exposure to radiation."
