Comparison of immediate and intermediate-term outcomes of intravascular ultrasound-guided versus angiography-guided intervention for type C coronary lesions

ABSTRACT

Background: the intravascular ultrasound [IVUS] is an invasive access technique that allows analysis of characteristics [qualitative and quantitative] of coronary atherosclerosis. Percutaneous coronary intervention [PCI] of complex lesions [i.e., American College of Cardiology/ American Heart Association class type C] remains challenging and the outcome may be compromised. The use of intravascular ultrasound [IVUS] to guide PCI was suggested to improve outcome:
