Brief summary
The purpose of this study is to compare revascularization strategy and its immediate results after augmented-reality computed tomography angiography (CTA) guided vs. standard angiography guided percutaneous coronary intervention (PCI) in native coronary lesions.
Detailed description
While stand-alone angiography is the first-line imaging modality for guidance of PCI, it has some inherent limitations which may result in suboptimal stent placement related to residual reference segment disease and stent underexpansion. Coronary CTA, on the other hand, can provide reliable measurements of the vessel size and lesion length as well as the visualization of the morphological features of coronary plaque, and has been suggested as potentially valuable for changing PCI technique. The AR-PCI trial has been designed as a single-center, investigator initiated and investigator sponsored, randomized (1:1), controlled, prospective clinical trial. It is hypothesized that the review of CTA datasets using augmented-reality glass in the catheterization laboratory could influence PCI treatment strategy and its immediate results by more adequate lesion coverage with less residual disease and better stent expansion as compared to traditional angiography-guided PCI alone.
Interventions
Angiographic guided PCI is coronary revascularization based on stand-alone angiography.
Augmented-Reality CTA guided PCI is coronary revascularization based on systematic use of CTA datasets displayed in augmented-reality glass plus coronary angiography.

Eligibility
Inclusion criteria
