Doctors at Kettering General Hospital in Northamptonshire are using a pioneering procedure to treat patients with heart problems.
Shockwave Coronary Intravascular Lithotripsy uses sonic waves to break down calcium deposits in arteries which can lead to blood clots and heart attack.
The hospital is one of only a few major heart centres in the world to use the technique.
Rosalie Mallett, 81, from Thrapston was one of the first patients to undergo the treatment at the hospital after having a heart attack. She was awake, under local aesthetic, as Dr Raju carried out the procedure - she went home the same day.
Dr Raju says it is an exciting new procedure that is 'simpler, safer and quicker' than previous treatments.
