Intravascular ultrasound (IVUS) has expanded our understanding of atherosclerotic
plaque morphology, and provides an opportunity to guide cardiovascular
interventions and evaluate results. Use of this technique requires understanding
of ultrasound physics, catheter differences, skills in vessel, plaque and stent
quantification and knowledge of artifacts and various physiologic and pathologic
findings. Optimal cardiovascular interventions should result in absence of inflow
or outflow obstruction, precise geographic landing, while attaining the largest
feasible luminal gain without plaque protrusion, vessel dissection or perforation
and, if deployed, with complete stent expansion and apposition to the vessel
wall. IVUS is safe, cost efficient and effectively optimises cardiovascular
interventions. In addition, IVUS improves outcomes when used to guide coronary
interventions using bare metal stents (BMS) and drug eluting stents (DES). The
role of IVUS in endovascular therapy is rapidly expanding. This review will focus
on the impact of IVUS in clinical practice.
