Active Comparator: Angiographic guided PCI
Angiographic guided PCI is coronary revascularization based on stand-alone angiography.
|
Procedure: Angiographic guided PCI
Angiographic guided PCI is coronary revascularization based on stand-alone angiography. |
|
Experimental: CTA guided PCI
CTA guided PCI is coronary revascularization based on systematic use of CTA plus coronary angiography.
|
Procedure: Augmented-Reality CTA guided PCI
Augmented-Reality CTA guided PCI is coronary revascularization based on systematic use of CTA datasets displayed in augmented-reality glass plus coronary angiography. |
