BACKGROUND:Percutaneous coronary intervention (PCI) in ostial lesions is one of the major challenges for contemporary interventional cardiology. Despite the technological advances, ostial lesions still present a higher rate of immediate and late adverse events when compared to non-ostial lesions. The objective of this study was to evaluate coronary ostial lesions treated with the Szabo technique. METHODS: Series of 10 patients, included between October and November 2011, treated by PCI using the Szabo technique to treat ostial lesions in main coronary arteries. Aorto-ostial lesions were excluded. RESULTS: Of the 10 patients treated, 7 were male, with ages ranging from 42 to 75 years and 60% had acute coronary syndromes without ST-segment elevation. The circumflex artery was treated in 6 patients and a 7 F catheter was used in 8 patients. In 3 patients, during the advancement of the stent to the lesion, both guidewires twisted, which was solved by partially retrieving the standard target vessel wire and positioning it again. Procedural success was observed in 90% of the cases. There were no hospital deaths, (re)infarctions or emergency revascularizations. CONCLUSIONS: In this study, the Szabo technique successfully treated ostial lesions in main coronary arteries, providing adequate positioning of the stent in most of the cases.
