A new method of testing mitral valve flow characteristics.
JOHN WRIGHT This has been evolved with a modified pulse duplicator and the use of a hot film probe for measuring velocity, direction, and turbulence. Many of the commercially available mitral valve prostheses are being investigated for their flow characteristics. In addition, efficiency is being examined and some unusual findings point to the possibility of a hydraulic ram effect in the normal ...

چکیده-پخش بار بهینه به عنوان یکی از ابزار زیر بنایی برای تحلیل سیستم های قدرت پیچیده ،برای مدت طولانی مورد بررسی قرار گرفته است.پخش بار بهینه توابع هدف یک سیستم قدرت از جمله تابع هزینه سوخت ،آلودگی ،تلفات را بهینه می کند،و هم زمان قیود سیستم قدرت را نیز برآورده می کند.در کلی ترین حالتopf یک مساله بهینه سازی غیر خطی ،غیر محدب،مقیاس بزرگ،و ایستا می باشد که می تواند شامل متغیرهای کنترلی پیوسته و گ...
Evaluation of diastolic blood flow dynamic of the left ventricle in dogs with mitral valve regurgitation using vector flow mapping
Mitral valve regurgitation (MVR) is a common valvular disease in dogs. Hydrokinetic evaluation of the blood flow within the ventricles has become possible by vector flow mapping (VFM), which shows the blood flow within the ventricles in vector and vortex flows. Blood flow within the left ventricle of MVR dogs was compared at different stages of MVR and to that of normal dogs. 14 normal dogs and...
متن کاملCharacteristics and management of cleft mitral valve.
OBJECTIVES We sought to highlight the clinical, morphologic, and pathogenetic features in patients with a cleft mitral valve (MV). BACKGROUND Few studies have addressed the morphologic features of cleft MV and the outcome of these patients. The pathogenetic features, including the developmental relation to an atrioventricular (AV) septal defect, remain unclear. METHODS We reviewed the patie...
متن کاملEffect of position on echocardiographic diagnosis of mitral valve prolapse
Echocardiography has been accepted as the diagnostic modality of choice for mitral valve prolapse (MVP). The determine the effect of position on echocardiographic diagnosis of MVP, we examined 693 consecutive patients referred to the echocardiography laboratory because of suspected MVP. First, patients were examined using the usual standard M-Mode echocardiography( left parasternal third or fou...
