OBJECTIVES: The jailed strut at the side-branch (SB) orifice may be a cause of delayed neointimal coverage and SB flow disturbance after single stenting to bifurcation. The aim of this study was to characterize the exact relationship between the jailed strut pattern at the SB orifice immediately after stent implantation and neointimal coverage of the jailed SB orifice in the chronic phase. PATIENTS AND METHODS: A total of 29 bifurcation (left anterior descending coronary artery and diagonal branch) lesions treated by optical coherence tomography-guide single-stent implantation and followed at 18 months after a percutaneous coronary intervention were included in this study...

BACKGROUND: The factors influencing genesis of atherosclerosis at specific regions within the coronary arterial system are currently uncertain. Local mechanical factors such as shear stress as well as metabolic factors, including inflammatory mediators released from epicardial fat, have been proposed. We analyzed computed tomographic (CT) attenuation of pericoronary adipose tissue in normal versus atherosclerotic coronary segments as defined by intravascular ultrasound (IVUS). PATIENTS AND METHODS: We evaluated the data sets of 29 patients who were referred for invasive coronary angiography and in whom IVUS of 1 coronary vessel was performed for clinical reasons...

We encountered two cases that resulted in unusual deflection of the protruded struts after proximal optimization technique (POT) with side branch (SB) dilation in coronary bifurcation stenting, when the guide wires recrossed into proximal cells of the struts overhung in the SB ostium. In one case, POT before SB dilation enabled adequate strut expansion with some deflection toward the distal SB, and subsequent SB dilation completed this deflection. In another case, POT after SB dilation resulted in the deflection toward distal main branch, opposite side of the previous case...

BACKGROUND: Data regarding bioresorbable vascular scaffolds (BVS) use in coronary bifurcation lesions are limited. The aim of this study was to compare mid-term clinical outcomes of all-comer patients treated with BVS versus everolimus-eluting stents (EES) for bifurcation lesions. METHODS: A total of 351 non-left-main bifurcation lesions in 323 all-comer patients were treated either with BVS (166 bifurcations in 147 patients) or EES (185 bifurcations in 176 patients)...

Four decades after its introduction into clinical practice, coronary balloon angioplasty is still used during most coronary interventions. Conventional balloon angioplasty is frequently used to predilate complex or severe lesions and remains of major value to optimise the results of stent implantation. Plain balloon angioplasty is still used alone in some anatomic scenarios where stent implantation is not desirable (very small vessels or diffuse lesions, large resistant thrombus burden, side branches of bifurcations)...

In the early days of coronary angiography, the precise quantification of luminal narrowing was challenging. The introduction of balloon angioplasty (percutaneous transluminal coronary angioplasty [PTCA]) by Andreas Grüntzig in 1977 was perhaps the greatest incentive to the development of quantitative coronary angiography (QCA). QCA has played a crucial role in evaluating interventional techniques and assessing the results of new technologies. With the advent of drug-eluting stents (DES), QCA metrics such as late lumen loss and diameter stenosis (restenosis) proved to be instrumental in assessing new technologies...

OBJECTIVES: To compare visual estimation with different quantitative coronary angiography (QCA) methods (single-vessel versus bifurcation software) to assess coronary bifurcation lesions. BACKGROUND: QCA has been developed to overcome the limitations of visual estimation. Conventional QCA however, developed in "straight vessels," has proved to be inaccurate in bifurcation lesions. Therefore, bifurcation QCA was developed. However, the impact of these different modalities on bifurcation lesion severity classification is yet unknown METHODS: From a randomized controlled trial investigating a novel bifurcation stent (Clinicaltrials...

OBJECTIVE: Percutaneous coronary intervention for coronary bifurcation lesion is very challenging, especially for true bifurcation lesions. Although the jailed semi-inflated balloon technique is one of the established methods for treatment of coronary bifurcation lesions, little is known regarding the configuration of the side branch orifice after stent implantation using this technique. METHODS: We report a 73-year-old male patient with angina pectoris who was successfully treated with percutaneous coronary stent implantation for a true bifurcation lesion of the right coronary artery with an obtuse angle using the jailed semi-inflated balloon technique...

The treatment of coronary artery bifurcation often represents a challenge for interventional cardiologist. Although several stenting techniques are available for the treatment of de novo coronary bifurcation lesions, over the last years, different studies have proposed and analysed the use of drug-coated balloon (DCB) in the treatment of coronary artery bifurcation lesions as an alternative treatment. To date, even considering those studies which have analysed a combined strategy (DCB+stenting) or a DCB-only approach, the evidences are scant and the results debatable...

There are limited data about clinical outcomes of biodegradable polymer biolimus-eluting BioMatrix stents (BP-BES) and durable polymer everolimus-eluting Xience stents (DP-EES) in real world practice. We sought to compare the clinical outcomes of BP-BES and DP-EES in real world cohorts of patients undergoing percutaneous coronary intervention. A prospective multicenter registry enrolled 999 patients treated with BP-BES and 1,000 patients treated with DP-EES. The primary outcome was target lesion failure, defined as a composite of cardiac death, target vessel-related myocardial infarction, or target lesion revascularization...

Contrast-induced nephropathy (CIN) is a serious complication in patients undergoing percutaneous coronary intervention (PCI), and is associated with higher morbidity and mortality. The limiting volume of contrast medium is safest and most reliable strategy for CIN prevention. Intravascular ultrasound (IVUS) serves as an attractive alternative imaging tool to angiography in many steps during PCI, thereby reducing the use of contrast agents. Here, we reported a case of successfully treated unprotected left main bifurcation lesion with heavily calcified and diffuse lesion under the IVUS-guided PCI using low volumes of contrast dye of total 12 cc in an elderly patient...

BACKGROUND AND AIM: 25-hydroxyvitamin D deficiency represents a widespread social problem but also an emerging risk factor for cardiovascular disease. Genetic variants of the Vitamin D Binding Protein (VDBP), the main transporter of vitamin D in the bloodstream, have been shown to account for a significant variability in the levels and systemic effects of vitamin D. We investigated whether the single nucleotide polymorphisms, rs7041 and rs4588, of VDBP are associated to the prevalence and extent of coronary artery disease...

Cardiovascular disease remains the most common cause of death worldwide. Enormous progress in the technology and applicability of percutaneous techniques to treat obstructive coronary heart disease has been made, and the number of percutaneous coronary interventions (PCI) is increasing. Coronary bifurcations are involved in a substantial number of PCIs and despite recent advances, bifurcation PCI remains a challenge in terms of immediate success and long-term outcome. Angiography has a limited capacity for showing important features of the 3 dimensional coronary vessel anatomy, position of stent struts and exact wire positions and is therefore suboptimal for guiding bifurcation PCI...

OBJECTIVE: To investigate outcomes in patients with ST-segment elevation myocardial infarction (STEMI) after treatment with the Stentys self-apposing stent (Stentys SAS; Stentys S.A.) for bifurcation culprit lesions. BACKGROUND: The nitinol, self-expanding Stentys was initially developed as a dedicated bifurcation stent. The stent facilitates a provisional strategy by accommodating its diameter to both the proximal and distal reference diameters and offering an opportunity to "disconnect" the interconnectors, opening the stent toward the side branch...
