CT angiography boosts PCI success in chronic total occlusion: trial

Preprocedural CCTA guided percutaneous coronary intervention is more effective than non-guided, say South Korean researchers

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.
