Core Tip
Core tip: Percutaneous intervention of ostial and bifurcation lesions is associated with higher rates of restenosis and procedural complications. Vessel anatomy, histology, and the variable angle of takeoff of ostial lesions contribute to the challenging nature of intervention. Lesion histology demonstrates greater calcification, rigidity, eccentricity as well as thicker muscular and elastic tissue, which contribute to greater elastic recoil. The Szabo two-wire technique provides accurate and complete stent positioning within the ostium, with less dependence on angiography. Intravascular imaging such as with intravascular ultrasound and optical coherence tomography (OCT) can confirm proper stent positioning. We describe two cases of successful percutaneous coronary intervention to bifurcation lesions using the Szabo technique and confirmation of correct placement in the ostium with OCT.
