Summary

 Background: The purpose of this study was to identify clinical and anatomical characteristics which may not benefit from RESCUETM catheter in patients with acute myocardial infarction (AMI).

 Methods: Sixty-six consecutive AMI patients, who had extensive thrombi in the right coronary artery (RCA), were enrolled in this study. We measured Thrombolysis in Myocardial Infarction (TIMI) frame count (TFC) immediately after performing RESCUETM catheter and defined unsuccessful reperfusion as TFC≧40. The patients were divided into two groups: TFC<40 group (n=55) and TFC≧40 group(n=11). The two groups were compared and multivariate and multivariate analyses were performed to identify clinical and anatomical factors in predicting unsuccessful reperfusion.

 Results: In a multivariate model, large vessel diameter and late recanalization were the independent predictors for unsuccessful reperfusion (p<0.05).

 Conclusion: Large vessel diameter and late recanalization are independently associated with unsuccessful reperfusion immediately after RESCUETM catheter in patients with AMI related to RCA.
