Revascularization techniques are being featured more prominently as endovascular treatments continue to select out complex cerebrovascular pathologies for open surgical management. The current healthcare environment requires decreased hospital stays and improved clinical outcomes despite the growing complexity of open surgical cases. Recent efforts to reduce operative room time and decrease risk for bypass surgery have focused on avoiding graft harvest and maintaining the entire bypass intracranial. The presented technique features an arborization bypass to serially anastomose the middle cerebral artery vessels allowing for proximal trapping of a complex aneurysm without graft harvest...

The anomalous origin of the entire coronary system from the right coronary sinus is a very rare anomaly. Here a patient with this rare anomaly, who developed acute coronary syndrome, requiring revascularization, is presented and treated successfully. His coronary angiographic findings are also discussed. We would like to highlight the rarity of the origin of all 3 coronary arteries from a single coronary trunk. The case also highlights the importance of using Amplantzer AR1 guiding catheter for such anatomical variations arising in the right coronary cusp...

In recent years, the retrograde tibiopedal approach is increasingly being used for revascularization of complex chronic total occlusions of infrainguinal arteries to bailout those cases where a guidewire was not possible to pass through the lesion from antegrade and therefore the treatment would have failed. The present popularity of this technique is in contrast to the paucity of data published so far. Nevertheless, from the reports that are available and from the authors' experience we conclude that it is not only a successful but also a safe technique...

BACKGROUND: In the past two decades, the introduction of robotic technology has facilitated minimally invasive cardiac surgery, allowing surgeons to operate endoscopically rather than through a median sternotomy. This approach has facilitated procedures for several structural heart conditions, including mitral valve repair, atrial septal defect closure and multivessel minimally invasive coronary artery bypass grafting. In this rapidly evolving field, we review the status of robotic cardiac surgery in Europe with a focus on mitral valve surgery and coronary revascularization...

AIM: We investigated the relationships of serum uric acid levels with the progression of atherosclerosis in patients with peripheral arterial disease (PAD) after treatment. METHODS: Subjects were male patients diagnosed with PAD. Atherosclerosis at the common carotid artery was evaluated based on its intima-media thickness (IMT). Leg arterial flow was evaluated by measuring ankle-brachial index (ABI) and exercise-induced decrease in ABI. RESULTS: Among various risk factors including age, blood pressure, adiposity, estimated glomerular filtration rate, and blood lipid, blood glucose, uric acid, fibrinogen and C-reactive protein levels, only uric acid levels showed significant correlations with ABI [Pearson's correlation coefficient, -0...

Inability to cross the lesion with a guidewire is the most common reason for failure in percutaneous revascularization (PCI) of chronic total occlusions (CTOs). An ostial or stumpless CTO is an acknowledged challenge for CTO recanalization due to difficulty in successful wiring. IVUS imaging provides the opportunity to visualize the occluded vessel and to aid guidewire advancement. We review the value of this technique in a single-centre experience of CTO PCI. This series involves 22 patients who underwent CTO-PCI using IVUS guidance for stumpless CTO wiring at our institution...

Reported here are the results of an experimental study on the response to low-intensity cavitation induced by low-frequency (4-6 W/cm(2), 20 kHz and 32.6 kHz) ultrasound of isolated human arterial samples taken during conventional myocardial revascularization operations. Studies have found that low-frequency ultrasound results in a significant (48%-54%) increase in isometric contraction force and does not depend on the number of exposures (10 or 20) or the time passed since the start of ultrasound (0, 10 and 20 min), but does depend on the frequency and location (internal or external) of the blood vessels for the application of ultrasound...

BACKGROUND AND OBJECTIVE: Percutaneous coronary intervention, despite being effective for coronary revascularization, causes in-stent restenosis due to neointimal hyperplasia in a large number of patients. The renin-angiotensin system is involved in neointimal hyperplasia. This study sought to evaluate seven gene polymorphisms of key renin-angiotensin system components, including angiotensinogen, angiotensin-converting enzyme and angiotensin II type 1a receptors, and their associations with in-stent restenosis in patients with coronary artery disease following coronary stenting...

Importance: Coronary artery calcium (CAC) is associated with coronary heart disease (CHD) and cardiovascular disease (CVD); however, prognostic data on CAC are limited in younger adults. Objective: To determine if CAC in adults aged 32 to 46 years is associated with incident clinical CHD, CVD, and all-cause mortality during 12.5 years of follow-up. Design, Setting, and Participants: The Coronary Artery Risk Development in Young Adults (CARDIA) Study is a prospective community-based study that recruited 5115 black and white participants aged 18 to 30 years from March 25, 1985, to June 7, 1986...

Determining the optimal treatment strategy for revascularization of coronary artery stenosis involves the use of fractional flow reserve (FFR). To improve the low clinical uptake of physiological lesion assessment to guide revascularization, the instantaneous wave-free period (iFR) was proposed as a simpler alternative to FFR that does not require adenosine administration. iFR is calculated as the ratio of blood pressure distal and proximal to a coronary artery stenosis during the diastolic wave- free period...

AIMS: Percutaneous coronary intervention (PCI) of severe coronary artery calcification (CAC) is challenging. The ORBIT II study demonstrated the safety and efficacy of orbital atherectomy (OA) in patients with severe CAC. Microparticulate liberated during OA may disturb coronary microcirculation. We evaluated OA treatment in patients with left ventricular systolic dysfunction. METHODS AND RESULTS: Patients were grouped by left ventricular ejection fraction (LVEF): 26-40% (n=33), 41-50% (n=90), and >50% (n=314)...

OBJECTIVE: Randomized trials support carotid endarterectomy (CEA) in asymptomatic patients with ≥60% internal carotid artery (ICA) stenosis. The widely referenced Society for Radiologists in Ultrasound Consensus Statement on carotid duplex ultrasound (CDUS) imaging indicates that an ICA peak systolic velocity (PSV) ≥230 cm/s corresponds to a ≥70% ICA stenosis, leading to the potential conclusion that asymptomatic patients with an ICA PSV ≥230 cm/s would benefit from CEA. Our goal was to determine the natural history stroke risk of asymptomatic patients who might have undergone CEA based on consensus statement PSV of ≥230 cm/s but instead were treated medically based on more conservative CDUS imaging criteria...

BACKGROUND: Although studies have demonstrated comparable efficacy and safety profiles of everolimus- and zotarolimus-eluting stents (EES and ZES, respectively) for a broad spectrum of coronary artery diseases, there is paucity of data concerning their safety and efficacy for coronary chronic total occlusions (CTOs). This study compared the clinical performance of EES and ZES following successful percutaneous coronary intervention for CTOs. METHODS: The cohort included 539 consecutive CTO patients who underwent successful PCI using EES (n=313) and ZES (n=226) between September 2006 and August 2014...
