For the past four years, Karmpaliotis has devoted much time to the retrograde and antegrade angioplasty, a procedure that can take four times as long as a stent. Since January, he and his team have performed 80 such procedures, with an established success rate of 89%, significantly more than significantly more than the national average of 65%, according to the hospital.
"Developments in guidewire technology, imaging technique, and coronary devices have contributed to the improved prognosis of patients affected by a CTO lesion," according to Current Cardiology Reports, in which "Enhancement in antegrade and retrograde techniques" also result in improved outcomes, the report stated.
Cardiac Interventions Today in 2008 described the strategies for confronting chronic occluded arteries as "conquering the last frontier of interventional cardiology."
The presence of CTOs often result in open heart surgery, though Karmpaliotis believes antegrade or retrograde angioplasty should be considered increasingly as a proper alternative option in carefully selected cases; to relieve a patient, too, of symptoms of angina, shortness of breath or compromised heart function.
In recent years, there has been much debate about the procedure in this country.
