Abstract 4539: A Technique to Enable Optimal Coverage of the Vessel Ostium by Anchoring the Stent at the Level of Te Ostium: 1-year Clinical and Angiography Outcomes
Background: Accurate stent placement, for optimal coverage of the vessel ostium, is necessary to reduce an otherwise important risk of restenosis. We sought to describe our initial results using a new technique, the “Szabo technique”.
Methods: 24 patients with significant ostial coronary lesions were prospectively included in the registry. The technique described by Szabo in 2005 was used to optimally cover the ostium of the stented vessel. After wiring the affected vessel, a second extra-support wire is positioned in the adjacent non-affected branch with the most proximal end passed through the last cell of the stent, thus inhibiting advancement and anchoring the stent in position.
Results: Patients were 69±10 years old, 37% were diabetic, 37% had 3-vessel disease. 36% of lesions were clasify as moderately/severily clacified The ostial left anterior descending artery (LAD) was treated in (19) 83%. Pre-dilatation was performed in all cases, using a cutting balloon in (12) 54%. A DES was implanted in 91%. There were no in-hospital adverse events. Repeat angiography was performed in (18) patients (81%) at 7.8±0.9 months. Restenosis was observed in only 1 patient who underwent repeat revascularization. At a mean of 12.6±3.5 months overall MACE was (2) 9.0%, (1 TLR, 1 MI, 0 cardiac death).
Conclusion: This new anchor wire technique for precise ostial coronary stenting provides accuracy and safety with excellent immediate angiographic results and mid-term outcomes with 4.5% TLR at 1 year.
