Impact of Intravascular Ultrasound-Guided Percutaneous Coronary Intervention on Long-Term Clinical Outcomes in Patients Undergoing Complex Procedures

This study sought to determine whether intravascular ultrasound (IVUS) guidance compared with angiographic guidance reduces long-term risk of cardiac death in patients undergoing complex percutaneous coronary intervention (PCI).Although IVUS is a useful tool for accurate assessment of lesion profiles and optimal stent implantation, there are limited data on long-term clinical outcomes between IVUS-guided and angiography-guided PCI for patients...
