Objective: To evaluate the effect of transcatheter aortic valve replacement(TAVR) using Venus-A valve for treating patients with severe aortic stenosis. Methods: In this prospective study, 101 consecutive severe aortic stenosis patients with high surgical risk(Society of Thoracic Surgeon(STS) score ≥4%) or at prohibitive surgical risk were enrolled from 5 academic cardiovascular centers in China(Fuwai hospital, the second affiliated hospital of Zhejiang university school of medicine, West China hospital of Sichuan university, the first affiliated hospital of Nanjing medical university, Ruijin hospital of Shanghai Jiaotong university school of medicine) from September 2012 to January 2015, and Venus-A valves were used in TAVR for these patients...

OBJECTIVES: Children with congenital heart disease may require long-term central venous access for intensive care management; however, central venous access must also be preserved for future surgical and catheterization procedures. Transhepatic venous catheters may be an useful alternative. The objective of this study was to compare transhepatic venous catheters with traditional central venous catheters regarding complication rate and duration of catheter service. DESIGN: Retrospective review of 12 congenital heart disease patients from September 2013 to July 2015 who underwent placement of one or more transhepatic venous catheters...

The cleavage of the A2 domain of von Willebrand factor (VWF) by the metalloprotease ADAMTS13 regulates VWF size and platelet thrombosis rates. Reduction or inhibition of this enzyme activity leads to thrombotic thrombocytopenic purpura (TTP). We generated a set of novel molecules called VWF-A2 FRET (fluorescence/Förster resonance energy transfer) proteins, where variants of yellow fluorescent protein (Venus) and cyan fluorescent protein (Cerulean) flank either the entire VWF-A2 domain (175 amino acids) or truncated fragments (141, 113, and 77 amino acids) of this domain...

BACKGROUND: The accuracy of screening ultrasound for venous thrombosis in asymptomatic patients is still a matter of debate. The VENUS study evaluated the accuracy of centrally adjudicated venous ultrasound against venography in patients after major orthopedic surgery and found the sensitivity of ultrasound to be poor for both proximal and distal deep vein thrombus (DVT). OBJECTIVES: To evaluate whether thrombus characteristics such as location or size influence the diagnostic performance of centrally adjudicated venous ultrasound...

BACKGROUND: Venography is currently used to assess the incidence of deep vein thrombosis (DVT) in dose-finding and confirmatory trials of new antithrombotic agents. Centrally adjudicated, complete compression ultrasound (CCUS) could be a non-invasive alternative to venography. OBJECTIVES: A substudy of two, similarly designed, phase IIb trials of a novel, oral anticoagulant for the prevention of venous thromboembolism after elective hip or knee arthroplasty was undertaken to validate CCUS against venography...

New onset focal weakness is relatively common in patients with Down syndrome (DS), and has broad differential diagnosis. Ten cases of new onset focal weakness in patients with DS were encountered or are currently being followed in two DS clinics, with a combined population of patients of approximately 850, for a clinic population prevalence of 1.2%. The median age at presentation was 4 years old (range 1 month-44 years). The causes of new onset focal weakness were: stroke from Moyamoya disease (two patients); stroke from vaso occlusive disease (one patient); stroke from venus sinus thrombosis (one patient); traumatic subdural hematoma (one patient); brain abscess (one patient); spinal cord injury (SCI) from cervical spinal stenosis (two patients); SCI from atlantoaxial instability (AAI) (one patient); and brachial plexus injury (one patient)...

CASE REPORT: A 14 year old patient showing bilateral frontal headache during the previous four months was studied. Ophtalmoscopic examination revealed presence of bilateral papilledema. Magnetic resonance angiography showed presence of thrombosis in upper sagital and transverse sinuses. Patient was treated with oral acetazolamide (500 mg a day), one month later, headhache had disappeared and papilledema decreased. DISCUSSION: Aseptic cerebral venus thrombosis is an infrecuent condition that often is cause of neurologic complications that may become severe...

Recent research has revealed a number of links between inflammation and coagulation. The protein C anticoagulant pathway appears to be the major pathway involved in the cross-talk between inflammation and coagulation. Studies indicate that inflammatory mediators can downregulate key components of the pathway through transcriptional control, proteolytic inactivation and oxidant damage. In turn, in vivo and in vitro studies have revealed mechanisms by which the components of the pathway may inhibit inflammatory responses...

BACKGROUND: Antiphospholipid antibody syndrome (APAS) is characterized by the presence of anticardiolipin antibodies (ACA) in association with thrombotic disorders of arterial and/or venus systems, spontaneous abortion(s) or thrombocytopenia. METHODS: In this multicenter study, 502 end-stage renal disease (ESRD) patients awaiting renal transplants were screened to determine the frequency of APAS, the potential risk associated with APAS, and strategies for therapeutic intervention...

Deep venus thrombosis may result in pulmonary embolism. In rare instances, embolization has occurred, not directly to the pulmonary arterial tree, but to the right heart chambers. Although the value of echocardiography in the diagnosis is well recognised, their is no consensus for the appropriate treatment. We report herein six cases of floating right atrial thrombi, diagnosed by echocardiography, in patients with pulmonary embolism, or unexplained shock or syncope. Surgical embolectomy was carried out in 4 patients, and thrombolytic therapy in 2, without in-hospital mortality...

Angiographic evidence of thrombus may have important implications during coronary stent deployment procedures. The periprocedural presence of thrombus has been shown to increase the risk of subsequent stent thrombosis. Coronary angioscopy is a new technology that may prove more accurate for the detection of coronary thrombus. Angiographic filling defects suspicious for thrombus were observed in 15 (22%) of 64 patients undergoing coronary angioscopy during stent implantation procedures. Angioscopy confirmed the presence of thrombus in 9 (60%) of these 15 patients...

BACKGROUND: Patient beliefs, values, and preferences are crucial to decisions involving health care. In a large sample of persons at increased risk for stroke, we examined attitudes toward hypothetical major stroke. METHODS AND RESULTS: Respondents were obtained from the Academic Medical Center Consortium (n = 621), the Cardiovascular Health Study (n = 321 ), and United Health Care (n = 319). Preferences were primarily assessed by using the time trade off (TTO)...

Central venous catheters play an integral part in the treatment of patients with a variety of illnesses. Complications, although not common, do occur. However, the benefits of these devices far outweigh the risks. Thrombosis, one of the most common problems, can be divided into three distinct clinical entities. The prophylaxis, diagnosis, pathogenesis, and treatment of central venus catheter-related thromboses are critical in the treatment of patients requiring long-term venous access.

Prostatic Intraepithelial Neoplasia (PIN) and prostatic cancer (PCA) are not caused by infection, allergic reaction, inadequate immunological response, ischemia, ageing, systemic hormones, carcinogens, nor prostatic ductal contents. PIN and PCA are apparently caused by increased inner acinar pressure due to partially blocked draining ducts. Only this explanation can account for all the observations about PIN and PCA. All other possible causes are disproved by specific observations. In order to further clarify the cause of PIN and PCA, it is important to discover if peripheral zone lesions cluster around ducts or blood vessels...

Encouraged by the effective prevention of arterial thromboembolism with a combination of ASA and anticoagulants (9), the present study was done in 77 patients with a single Starr-Edwards aortic ball valve. They received one gm. of ASA daily, then the dose of anticoagulants was reduced gradually and the drug discontinued on average five weeks later. Six arterial embolic episodes occurred in five patients, the incidence being 14.5 complications per 100 patients per year. Five emboli were cerebral, none of them serious, and one was removed from a femoral artery...
