Intravascular ultrasound (IVUS) permits detailed, high-resolution tomographic imaging of coronary architecture and enables the characterization of atherosclerotic lesions and plaque distribution. This unique value of IVUS easily explains and justifies why IVUS has found easy access to the clinical repertoire of a standard catheterization laboratory. Despite this fact, the contribution of IVUS findings relative to the total number of procedures performed in clinical catheterization laboratories can be considered small, and IVUS is seen primarily as an optional tool accompanying diagnostic or interventional procedures and as a mandatory tool mostly in angiographically ambiguous ostial or bifurcational lesions. In clinical trials, IVUS is used to assess changes that occur in vascular dimensions (remodeling) and plaque distribution during the disease process, during percutaneous interventions and at follow-up. One of the unique features of IVUS is that it is the only method to study remodeling in vivo. A standard image acquisition protocol is commonly applied to ensure premium quality of images and quantitative data. Motorized pullback devices are necessary to obtain reproducible length and volumetric measurements and provide uniform image acquisition. Ultrasound images are analyzed using manual tracing of acoustic interfaces. Since manual tracing is subjective, objective methods are currently being developed to minimize observer involvement. Fully automated segmentation of luminal and medial-adventitial boundaries has recently been demonstrated, but is still regarded as an experimental method. In the design of stent trials, IVUS is partially used to evaluate the effects of stent deployment on patient outcome. IVUS-guided stent implantation has been shown to result in less frequent clinically driven target vessel revascularization than angiographic guidance alone, although mortality and infarct rate are not affected. A current focus is on serial observation of plaque burden in lipid-lowering therapy.

“…Intravascular Ultrasound is a recent technique which provides a source of high quality medical imaginery for precisely quantifying arterial obstruction and in consequence for the assessment of coronary interventions (bypass, balloon angioplasty, stent deployment or atherectomy) [27], [9]. A catheter with a transducer mounted on its tip is placed inside the artery and rotated to generate, by emitting pulses of ultrasound and receiving echoes, planar cross-sections corresponding to the traversed arterial structure.…”

Drug-eluting stent (DES) intervention is now emerging as an alternative approach for unprotected left main coronary artery (ULMCA) other than coronary artery bypass graft (CABG). Untreated left main (LM) coronary occlusion is always associated with poor prognosis and high mortality rate. Collective data from numerous worldwide registries and results from randomized Synergy between Percutaneous Coronary Intervention with Taxus and Cardiac Surgery (SYNTAX) trial demonstrated that percutaneous coronary intervention (PCI) of ULMCA is a viable alternative in selected patient groups. Intravascular ultrasound (IVUS) provides valuable luminal and plaque details of coronary lesion, which enable precise lesion severity assessment compared to angiographic assessment. IVUS is important to assess intermediate lesion severity, optimizing stent deployment in complex lesions; therefore, reducing poststenting complication has been shown to improve acute procedural result and subsequent clinical outcomes. In the current review, we aimed to focus on the role of IVUS in LM coronary bifurcation lesions.
