Abstract

This poster demonstrates how intravascular ultrasound (IVUS) plays a role in the diagnosis and treatment of coronary artery disease (CAD). A percutaneous coronary intervention (PCI) is a commonly performed and minimally invasive treatment that is often enhanced by the use of IVUS. Catheters are inserted into peripheral arteries and revascularization of the coronary arteries is completed with the use of angioplasty balloons and stents. IVUS is used before an intervention to diagnose and measure stenotic lesions and used after to assess stent expansion and possible complications. Definitions, indications, and contraindications are included for IVUS and PCIs as well as general discussion of outcomes. Included research shows better patient outcomes for PCIs completed with IVUS than with angiographic guidance alone. IVUS is shown to increase the length and diameter of stents and postdilation balloons used during a PCI. Research also shows that ST-segment elevation myocardial infarction (STEMI) patients have better outcomes with IVUS use. Overall, patients have better outcomes after PCI with the enhancement of IVUS. The limited use of IVUS indicates the need for more extensive research and increased rates of implementation.
