To evaluate the effectiveness and safety of optical coherence tomography (OCT) in percutaneous coronary intervention (PCI) : a systematic review

Abstract

Background: Coronary heart disease is a common cause of death in Hong Kong. Percutaneous coronary intervention (PCI) is widely used to treat coronary vessel disease nowadays. Optical coherence tomography (OCT) is a high-resolution imaging technique which is suggested as a useful guide during PCI. It is getting more frequent to use OCT to image coronary arteries. There is a concern of the effectiveness and safety of this device. Aims: We performed a qualitative systematic review to evaluate the effectiveness and safety of OCT in PCI. Methods: A review of literatures published on or before Feb 2015 from online database identified 21 relevant studies for our review. Design: We carried out the synthesis using the meta-ethnography. Results: No complication was found to be correlated with OCT used. OCT yield a higher success rate than IVUS. Significant correlation was found between OCT and IVUS measured stent length. No significant difference were found between OCT and IVUS measured lumen and stent area. Conclusions: OCT is feasible and safe to use and it is a useful coronary imaging tool to use in PCI. More multicenter randomized control trails should be conducted to assess the effectiveness and weakness of OCT.
