Cerebral tissue oxygenation (oxygen tension, pO2) is a critical parameter that is closely linked to brain metabolism, function, and pathophysiology. In this work, we have used electron paramagnetic resonance oximetry with a deep-tissue multi-site oxygen-sensing probe, called implantable resonator, to monitor temporal changes in cerebral pO2 simultaneously at four sites in a rabbit model of ischemic stroke induced by embolic clot. The pO2 values in healthy brain were not significantly different among the four sites measured over a period of 4 weeks...

AIMS: We aimed to assess the efficacy and safety of vitamin K antagonist (VKA) monotherapy in atrial fibrillation (AF) patients undergoing transcatheter aortic valve implantation (TAVI). METHODS AND RESULTS: In 735 TAVIs since 2008 we identified 167 patients suffering from concomitant AF who received either VKA monotherapy (n=77), VKA plus single antiplatelet therapy (SAPT, n=41) or a triple anticoagulation regimen (n=49). Thromboembolic as well as bleeding complications were analysed for six months after TAVI...

BACKGROUND: Transcarotid access is an alternative route for transcutaneous aortic valve implantation (TAVI) in patients with impossible transfemoral access. AIMS: We evaluated the safety, effectiveness and early and late clinical outcomes of CoreValve(®) implantation via the common carotid artery. METHODS: Eighteen patients (10 men, 8 women; mean age 84±5 years) at high surgical risk (mean EuroSCORE II 16±13%) with significant peripheral artery disease underwent TAVI via common carotid artery access under general anaesthesia...

BACKGROUND: The ROCKET AF study evaluated once-daily rivaroxaban versus dose-adjusted warfarin for the prevention of stroke and systemic embolism in patients with atrial fibrillation (AF). In this analysis, we compared rivaroxaban with warfarin in patients with AF from China, East Asia, and the rest of the world (ROW). METHODS AND RESULTS: We assessed baseline demographics and interaction of treatment effects of rivaroxaban versus warfarin among patients from mainland China, other East Asian countries, and ROW...

INTRODUCTION: Minimally invasive adrenalectomy has become the gold standard for surgery of the suprarenal gland. Retroperitoneoscopic adrenalectomy with dorsal approach is preferred. The aim of our case report is to discuss potential complications that may arise from retroperitoneoscopic adrenalectomy, specifically an intra-operative injury of the inferior vena cava. CASE REPORT: A 47-year-old male patient was admitted to undergo elective adrenalectomy on the right side...

BACKGROUND AND PURPOSE: Chronic hypoperfusion from athero-stenotic lesions is thought to lead to better collateral recruitment compared to cardioembolic strokes. It was sought to compare collateral flow in stroke patients with atrial fibrillation (AF) versus stroke patients with cervical atherosclerotic steno-occlusive disease (CASOD). METHOD: This was a retrospective review of a prospectively collected endovascular database. Patients with (i) anterior circulation large vessel occlusion stroke, (ii) pre-treatment computed tomography angiography (CTA) and (iii) intracranial embolism from AF or CASOD were included...

INTRODUCTION: The Cox Maze III procedure is considered the gold standard open surgical procedure for management of atrial fibrillation. This article outlines a unique case of a para-atrial mediastinal hematoma following a bilateral thoracoscopic left atrial Maze procedure mimicking malignancy.

BACKGROUND: Blindness caused by soft tissue fillers is an extremely low-probability event, but it results in great concern because of its devastating consequences. Currently, the mechanism of an embolism is usually considered to be an accidental injection of fillers into the blood vessels of the face, such as a facial artery, and then retrograding into the ophthalmic artery system, which causes retinal ischemic necrosis. In addition, previous studies have shown that there are anastomoses between facial arteries and branches of the ophthalmic artery in cadavers...

Clinical experience has shown that allergic and non-allergic respiratory, metabolic, mental, and cardiovascular disorders sometimes coexist with bronchial asthma. However, no study has been carried out that calculates the chance of manifestation of these disorders with bronchial asthma in Saarland and Rhineland-Palatinate, Germany. Using ICD10 diagnoses from health care institutions, the present study systematically analyzed the co-prevalence and odds ratios of comorbidities in the asthma population in Germany...

OBJECTIVE: To describe the characteristics of infective endocarditis (IE) in octogenarians and assess their prognosis. METHODS: Patients with definite IE hospitalised at a referral centre between July 2008 and July 2013 were prospectively included. A total of 454 patients were divided into three groups: 230 patients under 65 years old, 173 patients between 65 and 80 years old, and 51 patients over 80 years old. The main end point was 1-year mortality. RESULTS: One-year mortality was higher in the ≥80 years old group (37...

AIM: Pulmonary Embolism (PE) is a relatively common cardiovascular condition, occasionally and tragically manifesting as Sudden Cardiac Arrest (SCA). The natural history of SCA complicating PE has been poorly evaluated.In this study, we described the management and outcome of PE-related SCA. METHODS: In this prospective population-based study, we included all patients admitted at hospital alive after out-of- hospital SCA, in Paris and suburbs, France (6.6 million inhabits), from May 2011 to September 2015...

Trousseau syndrome is defined as a variant of intravascular thromboembolism that is induced by cancer. It may manifest itself as cerebral embolisms in some cases; however, when the cancer is not diagnosed, this identification may be difficult. Therefore, cerebral embolisms are often treated without identifying the cancer, which can worsen a patient's condition. The purpose of this study was to determine the differences in clinical features between cerebral embolisms induced by cancer (Trousseau syndrome) and those that are due to other causes, such as cardiogenic embolisms and artery-to-artery stroke...

BACKGROUND: This study aims to investigate the role of the blood pressure index (BPI), which is a new index that we developed, in detection of right ventricular dysfunction (RVD) in acute pulmonary embolism (APE). METHODS: A total of 539 patients, (253 males and 286 females), diagnosed with APE using computer tomography pulmonary angiography were included in the study. The BPI was obtained by dividing systolic blood pressure (SBP) by diastolic blood pressure (DBP)...

BACKGROUND: To determine the predictive value of volumetrically measured lung perfusion defects (PDvol) and right ventricular dysfunction on dual-energy computed tomography angiography (DE-CTA) for predicting all cause mortality in patients suspected of pulmonary embolism (PE) but without evident thromboembolic clot on CTA. METHODS: 448 patients underwent DE-CTA on a 64-channel DSCT system between January 2007 and December 2012 for suspected PE, of which 115 were without detectable thromboembolic clot on CTA...

Surgical embolectomy in acute pulmonary embolism is usually reserved for patients with massive pulmonary embolism presenting with cardiogenic shock, or for whom thrombolysis is absolutely contraindicated or has failed. Incomplete removal of thrombotic material lodged in the distal pulmonary arterial bed is considered an important cause of persistent pulmonary hypertension. Retrograde pulmonary embolectomy is an adjunct to conventional pulmonary embolectomy, resulting in more complete embolectomy, specifically of material lodged in the distal pulmonary arterial bed...

A solitary fibrous tumor of the pleura (SFTP) presenting with an aberrant arterial supply from the abdominal aorta is extremely rare, and it may be difficult to distinguish from intralobar sequestration (ILS). We report the case of a 38-year-old woman who presented with acute chest pain and was subsequently found to have a 17.5-cm intrathoracic mass. After preoperative arterial embolization of its feeding vessel, this presumed ILS was resected. However, the intraoperative findings revealed a benign SFTP. Here we discuss a unique presentation of a large SFTP radiographically mimicking an ILS, and we propose a safe management strategy for this entity...
