The success rate of percutaneous coronary intervention (PCI) for chronic total occlusion is improved by performing coronary CT angiography (CCTA) beforehand, trial South Korean results show.
The Korean CCTA-CTO study assessed the value of preprocedural CCTA on the success rate of PCI for chronic total occlusion in 400 patients.
