Background: The purpose of this article is to investigate the functional relevance of coronary collateral circulation and estimate the quality of the distal run-offs in patients with coronary chronic total occlusion (CTO).
Methods: We analyzed the 267 consecutive patients who underwent PCI for CTO. In 119 patients, the distal portion of total occlusion was filled with ipsilateral collateral connections (ipsilateral group), and in 103 patients, it was filled with contralateral collateral connections (contralateral group). The target vessel diameter and dilatation rates of the groups were evaluated and compared for the echocardiographic parameters.
Results: The principal finding in this study is that mean value of the target vessel diameter beyond occlusion was significant higher in the contralateral group than in the ipsilateral group (p<0.05). The LVEF values before PCI in the contralateral group were significantly higher than in the ipsilateral group. However, Increase in LVEF after PCİ were significantly higher in the ipsilateral group than contralateral group (p<0.05).
Conclusion: Our study results concerning contralateral circulation in patients with CTO have shown less negative vessel remodelling after CTO. We also showed that the increases of LVEF after PCI, the ipsilateral group had significant increases compared with the contralateral group.
