Abstract

405 Long-term Outcomes of Percutaneous Therapy for True Bifurcation Lesions Treated with Drug-eluting Stents Using the “Shunt” Technique Pratap Shetty ∗, Nigel Jepson, Robert Giles, Daniel Friedman, Warren Walsh, Roger Allan, Mark Pitney Prince of Wales Hospital, Randwick, NSW, Australia Background: A standardised two stent technique, (“shunt stenting”) has been usual practice for treating true bifurcation lesions involvingmajor side branches (>2.25mm) at our institution. We report procedural and follow up data on the first 254 patients. Methods: Database data collection on all PCI lesions and procedures is collectedprospectively at our institution.We reviewed procedural details between November 2002 and January 2008. Follow-up was obtained through telephone interview and clinical review. Results:Out of 442 bifurcations treated, 254 were “shunt” stented. 75.6% were males with a mean age of 62.1 years. Acute coronary syndrome (53.2%) was the most common indication for angioplasty. Glycoprotein IIb/IIIa inhibitor was used in 44.9%. The commonest lesion was LAD/Diagonal (66.1%). Cypher stents were used in 80%, Taxus in 10%. The average stent diameter used was 2.84mm (main branch) and 2.53mm (side branch). Procedural success with no MACE was obtained in 99.6% o t a
