It is standard practice for clinicians to consider echocardiographically-measured left ventricular wall thickness when estimating the severity of aortic stenosis. Most consider the degree of wall thickness above normal limits is in proportion to ventricular hypertrophy. Employment of wall thickness information to assess aortic stenosis severity, while generally reliable, can occasionally be mis...

PURPOSE Bladder wall thickness has been reported to be associated with overactive bladder (OAB) in women. Diabetic women have an increased risk for OAB syndrome and may have an increased risk for bladder wall thickness. METHODS A total of 235 female patients aged 40 to 75 years were categorized into four groups. The first group consisted of women free of urgency or urge urinary incontinence. ...

OBJECTIVES We investigated the prognostic impact of atherosclerosis and wall thickness of the ascending aorta in patients undergoing coronary artery bypass grafting (CABG). METHODS A series of 781 patients who underwent CABG and in whom epiaortic ultrasound was performed to assess the status of the ascending aorta and to measure the thickness of its anterior and lateral walls were the subject...

the emarat pb-zn mine is located at about 80 km south of the city of arak , iran. i the present mine-scale litho geochemical survey 56 hanging wall samples and 37 footwall samples were taken form exploratory tunnels, drillholes and open pit all samples were taken in the range of 0-40 m from pb-zn veins. the relationship between three variables including concentration of zn in wallwork, distance...

Although the importance of lateral femoral wall integrity is increasingly being recognised in the treatment of intertrochanteric fracture, little attention has been put on the development of a secondary post-operative fracture of the lateral wall. Patients with post-operative fractures of the lateral wall were reported to have high rates of re-operation and complication. To date, no predictors ...

Background Atrial fibrillation (AF) is the most common cardiac arrhythmia. It is often treated using catheter ablation, which aims to isolate arrhythmogenic regions by delivering localized energy. Whereas an insufficient energy delivery can lead to AF recurrence, excessive power can cause potentially lethal complications. Knowledge of atrial wall thickness can help select an optimal amount of e...

Measurement of pipeline wall thickness is one of the main contents of nondestructive inspection on offshore oil pipeline. A novel approach based on the marginal spectrum of the Hilbert-Huang transform is proposed for ultrasonic echo signal processing. The demodulated ultrasonic echo signal contains the thickness information of pipeline wall, which is an approximately periodic signal. The margin...

The present study investigates effects of surrounding tissues and non-uniform wall thickness on the biomechanics of the thoracic aorta. We construct two idealised computational models exemplifying the importance of surrounding tissues and non-uniform wall thickness, namely the uniform-thickness model and the histology image-based model. While the former neglects a connective tissue layer surrou...

The most prominent feature of sheet material forming process is an elastic recovery phenomenon during unloading which leads to springback and side wall curl. Therefore evaluation of springback and side wall curl is mandatory for production of precise products. In this paper, the effects of some parameters such as friction coefficient, sheet thickness, yield strength of sheet and blank-holder fo...

AIMS This study investigated the functional outcome of wall-thinned, akinetic myocardium after revascularization and evaluated the accuracy of dobutamine echocardiography in predicting post-revascularization functional recovery with the assessment of end-diastolic wall thickness in chronic ischaemic patients. METHODS AND RESULTS Fifty-three patients underwent dobutamine echocardiography befor...
