D-85 | Gender Disparities in Hospital Outcomes of Percutaneous Coronary Intervention in Patients With Chronic Total Occlusion of Coronary Artery

recanalization (5.5 vs. 14.8%,P<0.00001).At 5 years, survival was significantly higher in those patients with a successful revascularization (93.5 vs. 88.0%,P0.02).In addition, there was a significantly higher survival free of MACE (63.7 vs. 41.7%,P<0.0001), with the majority of events reflecting the need for repeat intervention.Independent predictors for survival were successful revascularization, lower age, and the absence of diabetes mellitus and multivessel disease.. Conclusions: Successful percutaneous revascularization of a CTO leads to a significantly improved survival rate and a reduction in major adverse events at 5 years.Most events relate to the need for repeat reintervention, and the introduction of drug-eluting stents, with lowrestenosis rates, encourages the development of technologies to improve recanalization success rates.However, failed recanalization may be associated acutely with an adverse event, and new technologies must focus on a safe approach to successful recanalization.
