The data presented in this article are related to the research article entitled "Optical coherence tomography guidance for the management of angiographically intermediate left main bifurcation lesions: early clinical experience" [1]. In this article we reports details about our clinical experience with frequency domain-optical coherence tomography (FD-OCT) guidance for the management of patients with left main (LM) bifurcation lesions of intermediate angiographic severity. LM patients were assessed by FD-OCT and, on the bases of the findings, managed by myocardial revascularization or conservative treatment (revascularization deferral)...

Ischemic lesion is a common cause of various diseases in humans. Brain tissue is especially sensitive to this type of damage. A common reason for the appearance of an ischemic area is a stop in blood flow in some branch of the vasculature system. Then, a decreasing concentration gradient results in a low mean level of oxygen in surrounding tissues. After that, the biochemical ischemic cascade spreads. In this review, we examine these well-known events from a new angle. It is stressed that there is essential evidence to predict the formation of an ischemic micro-area at the base of vascular bifurcation geometries...

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)...

INTRODUCTION: Surgical endarterectomy is the preferred method for treating occlusive disease of the common femoral artery (CFA). However, endarterectomy is not always straightforward in cases with heavily calcified plaque. To overcome this limitation, a new method for decalcification, which utilizes a Cavitron ultrasonic surgical aspirator (CUSA) has been developed. REPORT: The method involves full exposure of the calcified lesion. Following an arteriotomy, protruding calcification is removed using the CUSA, taking care to avoid vessel perforation...

BACKGROUND: Although the PED has proven to be an excellent option for ICA aneurysms, the rate of occlusion remains difficult to predict and factors associated with aneurysm occlusion are not well elucidated. This study aimed to investigate predictors and the rate of occlusion for aneurysms along the ICA. METHODS: 117 saccular ICA aneurysms treated with the PED were studied. Occlusion rates were divided among 4 groups. Group A [lesions > 10 mm in the proximal ICA (petrous to the superior hypophyseal segments)]...

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...

A 68-year-old woman presented with generalized seizure due to the left internal carotid artery (ICA) aneurysmal compression of the ipsilateral medial temporal lobe. Computed tomography angiography (CTA) revealed multiple aneurysms of the right persistent primitive hypoglossal artery (PPHA), the right ICA, and the right anterior cerebral artery (ACA). The right PPHA originated from the ICA at the level of the C1 and C2 vertebral bodies and passed through the hypoglossal canal (HC). The PPHA aneurysm was large and thrombosed, which was located at the bifurcation of the right PPHA and the right posterior inferior cerebellar artery (PICA), projecting medially to compress the medulla oblongata...

The aim of this study was to analyse the flow dynamics in an idealised model of the aorta-renal bifurcation using flow visualisation, with a particular focus on the effect of aorta-to-renal flow ratio and flow spirality. The recirculation length was longest when there was low flow in the renal artery and smaller in the presence of spiral flow. The results also indicate that patients without spiral flow or who have low flow in the renal artery due to the presence of stenosis may be susceptible to heightened development of atherosclerotic lesions...

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...

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...
