In New Zealand heart disease is the leading cause of death, killing about 16 people every day but medical science is finding new ways to battle the problem.
Cardiologist Doctor John Ormiston says the use of stents before being replaced by a permanent implant is successful but risky, but changes to the stent system could change the way cardiovascular surgery works.
