“Sepal wire technique”--a novel technique for aorto-ostial left main stenting

Aorto-ostial left main (LM) percutaneous coronary intervention (PCI) remains a challenge in interventional cardiology, as precise positioning of stents using conventional angiographic landmarks is difficult. Previously described techniques either involve the use of additional complex steps or commercially available special devices that carry extra costs. We describe a novel technique for ostial LM stent positioning that makes use of a simple additional workhorse wire curling back into the aorta like the sepal of a flower.
