Abstract
OBJECTIVE:
This study aims to investigate failure factors in retrograde wire-guided cannulation (retrograde approach) for the treatment of coronary chronic total occlusion (CTO).
METHODS:
Data of 285 patients treated for CTO using retrograde approach in the General Hospital of Shenyang Military Region from August 2004 to May 2016 were collected.
RESULTS:
The average age of the 285 patients was 63.89
CONCLUSION:
Based on the present study, the success rate of retrograde approach for CTO was negatively correlated with the number of diseased vessels and collateral circulation. It was furthermore of importance whether anterograde intervention for CTO target vessels was previously performed and whether other vessels beside CTO vessels were intervened, which were also risk factors.
