OBJECTIVES: The aim of this study was to report clinical outcomes in patients treated in routine practice 2 years after everolimus-eluting bioresorbable stent (BRS) implantation. BACKGROUND: Long-term results in patients undergoing BRS implantation in routine clinical practice are sparse, and existing evidence from randomized trials considers mostly selected patients. METHODS: The ISAR-ABSORB registry enrolled consecutive patients undergoing BRS implantation in routine clinical practice at 2 high-volume centers in Germany...

Image assessment of the arterial system plays an important role in the diagnosis of cardiovascular diseases. The segmentation of the lumen and media-adventitia in intravascular (IVUS) images of the coronary artery is the first step towards the evaluation of the morphology of the vessel under analysis and the identification of possible atherosclerotic lesions. In this study, a fully automatic method for the segmentation of the lumen in IVUS images of the coronary artery is presented. The proposed method relies on the K-means algorithm and the mean roundness to identify the region corresponding to the potential lumen...

OBJECTIVES: Although drug eluting stents (DES) have documented convenience in bifurcation lesions, possible unfavorable effects on small side branch ostium (SBO) remain a question. We aimed to explore the effects of DES on small jailed SBs (1.5-2.25 mm) which originated from the lesion on the main vessel and were not treated with either stenting or balloon dilatation. METHODS: Angiographic data of 107 consecutive patients (129 SB) with Medina 1,1,1 or 1,1,0 lesions were evaluated at the time of procedure and at the follow-up...

INTRODUCTION: The intentional strategy (aggressive side branch (SB) protection strategy: elective two-stent strategy or jailed balloon technique) is thought to be associated with lower SB occlusion rate than conventional strategy (provisional two-stent strategy or jailed wire technique). However, most previous studies showed comparable outcomes between the two strategies, probably due to no risk classification of SB occlusion when enrolling patients. There is still no randomised trial compared the intentional and conventional strategy when treating bifurcation lesions with high risk of SB occlusion...

OBJECTIVES: The present study aimed to develop a swine coronary bifurcation model. BACKGROUND: In human coronary bifurcation lesion, atherosclerotic plaques are usually observed in the lateral wall, whereas the flow divider regions are spared. There is currently no suitable coronary bifurcation animal model, on which a new stent can be tested. METHODS: We developed a novel directional heat injury catheter, which comprised of a non-compliant balloon catheter (diameter: 3...

OBJECTIVE: High-degree stenosis of both innominate (IA) or left common carotid artery (CCA) and carotid bifurcation is uncommon but still represents a significant challenge to interventionists in many aspects including techniques, timing, and priority. There are several strategies for intervention that have been reported in the literature. A well-described, less-invasive strategy for extracranial tandem carotid lesions is concomitant carotid endarterectomy (CEA) with retrograde carotid angioplasty and stenting (CAS)...

Optical coherence tomography (OCT) allows full volumetric segmentation of the lumen. However, for the estimation of stent under-expansion we still rely on the conventional method (CM) of single cross-sectional narrowing compared with reference vessel, likely masking true lesion significance, especially for bifurcations and tapered vessels. We, therefore, suggest a novel concept of volumetric metrics that take into account vessel tapering and major side branches and is capable of obtaining ideal lumen area for every frame of the stent by OCT...

We report a case of an 81-year-old man, hospitalized for sepsis unresponsive to targeted antibiotic therapy, who underwent abdominal aortic aneurysmectomy with stent placement before 12 years. Point-of-care ultrasound examination showed the presence of a voluminous and inhomogeneous lesion adjacent to the anterior wall of aortic bifurcation with pulsatile flow from the aorta into the lesion, highlighted by Color-Doppler, and peripheral (closely with intestinal loops) floating hyperechoic spots marked by posterior comet tail artifact, suggestive for the presence of air bubbles...

Percutaneous coronary interventions (PCIs) involving coronary bifurcation lesions are associated with adverse outcomes compared with non-bifurcation lesions. The Tryton Side Branch Stent has been developed to improve clinical outcomes after bifurcation PCI. Areas covered: We will discuss observational data (clinical registries and intravascular imaging studies) and randomized data from the TRYTON trial (comparing Tryton [used in combination with a main branch drug-eluting stent (DES)] with side branch balloon angioplasty [in combination with a main branch DES; also referred to the provisional strategy])...

According to the TASC II and the Russian National Guidelines on management of patients with lower limb arterial diseases, in patients with type C and D lesions of the arterial bed performing aortofemoral bifurcation bypass grafting is preferable. Laparoscopic technique makes it possible to combine advantages of minimally invasive surgery with well-known remote results of open reconstructive operations on the aortoiliac segment. The study included a total of 54 patients undergoing treatment at the Cardiosurgical Department of Clinic No 1 of the Volgograd State Medical University over the period from January 2012 to September 2015...

Acute and chronic cerebral circulatory impairment is a very commonly encountered type of neurological diseases, annually affecting more than six million people worldwide. The absolute majority of all cases are associated with atherosclerosis of cerebral arteries. Surgical intervention in a stenotic lesion of the internal carotid artery (ICA) is a method of preventive treatment with confirmed efficacy. Eversion carotid endarterectomy (ECEA) is currently the most commonly used 'open' operation for this cohort of patients...

INTRODUCTION: Mean platelet volume (MPV) was proved to be a reliable prognostic factor in cardiac patients. However, platelet distribution width (PDW) was disclosed to be more specific marker of platelet reactivity. The aim of study was to evaluate whether baseline PDW value can predict the outcome in patients undergoing percutaneous coronary interventions (PCI) with drug-eluting stent implantation within coronary bifurcation lesions. MATERIAL AND METHODS: It was a two-center observational study, which included patients who underwent PCI within bifurcation lesions between January 2014 and December 2014...

OBJECTIVES: Percutaneous coronary intervention (PCI) of the left main (LM) or proximal left anterior descending artery (pLAD) is considered high-risk as these segments subtend substantial left ventricular myocardial area. We assessed the patterns and associations between dual antiplatelet therapy (DAPT) cessation and 2-year outcomes in LM/pLAD vs. other PCI from the all-comer PARIS registry. METHODS: Two-year major adverse cardiovascular events (MACE) were a composite of cardiac death, myocardial infarction, definite/probable stent thrombosis or target lesion revascularization...

Ostial lesions present unique challenges for percutaneous coronary intervention (PCI). These lesions are often more calcified, fibrotic, rigid, and more prone to elastic recoil. Intervention on these lesions is associated with higher procedural complications and higher rates of restenosis. Ostial lesions require precise stent placement in the ostium with the absence of side branch compromise. Accurate stent placement in the ostium without side branch compromise is difficult to accomplish with angiography alone...
