news, nationalUntil now, performing keyhole heart valve replacement surgery was a bit like trying to cook the perfect steak, says the Australian doctor who has revolutionised the procedure. Prior to this pressure-regulated valve deployment technique being developed, studies showed more than half of patients undergoing the surgery had a leak that was at least mild in severity, Ng says. "The parameters for under- or over-filling are somewhat subjective, so there is variation case-by-case and hospital-by-hospital in terms of valve deployment practice." "By controlling the optimal pressure for deployment, we provide a new level of precision for this important procedure." "Our technique makes deployment of valves at the border zone very simple and with excellent results."
