Intravascular Ultrasound Imaging–Guided Versus Coronary Angiography–Guided Percutaneous Coronary Intervention: A Systematic Review and Meta‐Analysis

Background Intravascular ultrasound ( IVUS ) guidance during percutaneous coronary intervention ( PCI ) offers tomographic images of the coronary vessels, allowing optimization of stent implantation at the time of PCI . However, the long‐term beneficial effect of IVUS over PCI guided by coronary angiography ( CA ) alone remains under question. We sought to investigate the outcomes of IVUS ‐guided compared with CA ‐guided PCI . Methods and...
