Quantitative Coronary Angiography Versus Intravascular Ultrasound GUIDancE for Drug-Eluting Stent Implantation

In the quantitative coronary angiography-guided group, sirolimus-eluting Orsiro/Orsiro mission stent size and length is chosen to cover the entire length of the culprit lesions according to quantitative coronary angiography measurements. Selection of the sirolimus-eluting Orsiro/Orsiro mission stent size should be guided by both quantitative coronary angiography measurement and visual estimate, and is recommended to be based on distal reference vessel diameter by quantitative coronary angiography (distal reference vessel diameter by quantitative coronary angiography plus \~10% of distal reference vessel diameter).

In the intravascular ultrasound -guided group, sirolimus-eluting Orsiro/Orsiro mission stent size and length is selected by intravascular ultrasound measurements.
