“…[8][9][10][11] Although the occlusion of small side branches is well-tolerated, 12) occlusion of large side branches may result in significant adverse clinical events. 13) The presence of ostial narrowing that arises from within or just beyond the diseased portion is a powerful predictor of side branch occlusion. 14) As ostial narrowing was present in our case, we sought to protect D 2 with protective wire in order to avoid side branch injury.…”

SUMMARYCutting balloon angioplasty (CBA) was performed in a patient with in-stent restenosis (ISR) which had an important side branch. We used a hydrophilic polymer-coated guide wire for side branch protection during CBA. After CBA was successfully performed, the cutting balloon and guide wire were microscopically examined and proven to have suffered minor damage which, in itself, did not disturb the procedure. Hydrophilic polymercoated wire might be an effective and safe choice for ISR which needs to be treated by CBA while protecting an important side branch. (Jpn Heart J 2003; 44: 565-573)

“…181,[184][185][186] Treatment of bifurcations with directional atherectomy (without stenting) has been shown to improve the immediate procedural outcome compared with balloon dilatation alone, but the incidence of restenosis remains high. 187 The use of coronary stents has improved the treatment of bifurcation lesions, but it is technically challenging and there is still a high incidence of compromising the branch vessel.…”

The use of intravascular ultrasound catheters to produce images of lumen and plaque cross-sectional areas has had a profound effect on the practice of interventional cardiology. This imaging modality provides, for the first time, a low-power microscopic view of vascular anatomy within a living patient. This article will review some of the advantages of intravascular ultrasound imaging compared with angiography when used for diagnostic or interventional therapeutic procedures.Copyright 1999 by W.B. Saunders Company C oronary angiography is the primary mode of imaging coronary artery disease and guiding interventional procedures. Although coronary angiography was essential for the development of catheter-based coronary interventions, as the complexity of interventional cases increased, several limitations of angiography surfaced. Problems associated with coronary intervention, such as acute closure and restenosis, are related in part to properties of the lesion. Angiographic studies have reported inconsistent predictors of such adverse events. 1,2 One of the main reasons for this inconsistency is the limited power of angiography to delineate the complex anatomy of coronary atherosclerotic lesions. Intravascular ultrasound (IVUS) is a technique that provides two-dimensional, tomographic views of the coronary lumen and wall morphology in vivo, which has several advantages compared with angiography. 3 This article reviews the limitations of angiography and describes the information that IVUS imaging provides to complement angiography during diagnostic and interventional procedures. The ability of IVUS to evaluate lesion characteristics and dimensions alters therapeutic decisions and permits the operator to optimize each intervention. Lesion EvaluationEvaluation of coronary atherosclerotic lesions by angiography has been described by the joint American College of Cardiology/American Heart Association (ACC/AHA) committee. 4 This system delineates lesions by the degree of eccentricity and complexity. However, this analysis is limited by the ability of angiography to visualize only the lumen and not the atherosclerotic plaque itself. 91IVUS provides new insights for lesion evaluation because it produces a tomographic view of the artery and it is the only technique that permits visualization of the diseased artery wall in vivo. This capability is especially useful for diagnosing disease when vessels overlap or if there is a short stenosis. In addition, IVUS images are at a higher magnification than angiography, and its internal scale has been shown to be more accurate than angiographic assessment of plaque dimensions. Moreover, the ability of angiography to provide information on tissue characterization is limited. The following discussion will attempt to describe these differences between angiography and IVUS. Tomographic ImagingAn angiogram shows a longitudinal, two-dimensional view of the lumen of the vessel and does not directly show us the pathology, that is, the atherosclerotic plaque. If the plaque impinges on...

“…To lower the risk of plaque shift, the "kissing" balloon technique was developed [5]. However, the results after balloon dilatation of bifurcation lesions are frequently suboptimal with a high incidence of complications and restenosis [4,[6][7][8]. Stent implantation on both the parent vessel and the side branch, which is called "kissing stents," is a useful technique for maintaining maximum expansion of both vessels.…”

Background: Percutaneous Coronary Intervention (PCI) of bifurcation disease remains a challenge in terms of procedural success rate as well as long term Major Adverse Cardiac Events (MACE), Target Lesion Revascularization (TLR), restenosis, and Stent Thrombosis (ST). Bifurcation interventions, when compared with nonbifurcation interventions, have a lower rate of procedural success and a higher rate of restenosis.
