摘要：BACKGROUND The prognostic value of coronary collateral circulation(CC)in patients undergoing chronic total occlusion(CTO)percutaneous coronary intervention(PCI)is underdetermined.The purpose of the study was to assess the prognostic va-lue of current two CC grading systems and their association with long-term outcomes in patients with CTO underwent PCI.
METHODS We consecutively enrolled patients with single-vessel CTO underwent PCI between January 2010 and December 2013.All patients were categorized into well-developed or poor-developed collaterals group according to angiographic Werner's CC(grade 2 vs.grade 0-1)or Rentrop(grade 3 vs.grade 0-2)grading system.The primary endpoint was 5-year cardiac death.
RESULTS Of 2452 enrolled patients,the overall technical success rate was 74.1%.Well-developed collaterals were present in 686 patients(28.0%)defined by Werner's CC grade 2,and in 1145 patients(46.7%)by Rentrop grade 3.According to Werner's CC grading system,patients with well-developed collaterals had a lower rate of 5-year cardiac death compared with those with poor-developed collaterals(1.6%vs.3.3%,P = 0.02),those with suboptimal recanalization was associated with higher rate of 5-year car-diac death compared with optimal recanalization(4.7%vs.0.8%,P = 0.01)and failure patients(4.7%vs.1.6%,P = 0.12).However,the similar effect was not shown in Rentrop grading system.
CONCLUSIONS In patients with the single-vessel CTO underwent PCI,well-developed collaterals by Werner's CC definition were associated with lower rate of 5-year cardiac death.Werner's CC grading system had a greater prognostic value than Rentrop grading system in patients with CTO underwent PCI.
