Abstract
OBJECTIVES: To investigate the impact of the success or failure of chronic total occlusion (CTO) interventions on the clinical outcomes in the current drug-eluting stent (DES) era. BACKGROUND: The impact of the successful CTO intervention on long-term clinical outcomes still remains unclear. METHODS: Between 2007 and 2009, a total of 2568 patients with CTO were followed in a multicenter Korean CTO registry. Of these, successful recanalization with DESs occurred in 2045 patients (successful CTO group), whereas failure occurred in 523 patients (failed CTO group). RESULTS: The occurrence of the composite of cardiac death and myocardial infarction (MI) was compared between the successful CTO and failed CTO groups. During follow-up (median duration, 729 days), the occurrence of cardiac death or MI was significantly lower in the successful CTO group than in the failed CTO group (1.7% vs 3.3%; hazard ratio, 0.50; 95% confidence interval, 0.28-0.91; P=.02) and the cumulative occurrence in the successful CTO group was also significantly lower than in the failed CTO group (1.7% vs 3.0%; P=.03) by the Kaplan-Meier method. The successful CTO group had a significantly lower need for bypass surgery than the failed CTO group (0.2% vs 2.5%; P<.001). In multivariate analysis, procedural success of CTO (odds ratio, 0.51; 95% CI, 0.29-0.92) was significantly predictive of the occurrence of cardiac death or MI, together with age and left ventricular ejection fraction <40%. CONCLUSION: This registry study demonstrated that successful CTO intervention with DESs compared to failed CTO intervention was associated with lower event rates during follow-up.
