Opening and closing characteristics of the aortic valve after different types of valve-preserving surgery.
BACKGROUND The surgical approach to aortic root aneurysm and/or dissection remains controversial. The use of valve-sparing operations, which are thought to have many advantages, is increasing. We hypothesized that the particular technique and type of surgery could influence valve motion characteristics and function. Therefore, we studied the instantaneous opening and closing characteristics of ...
متن کاملComparison the Sensitivity Analysis and Conjugate Gradient algorithms for Optimization of Opening and Closing Angles of Valves to Reduce Fuel Consumption in XU7/L3 Engine
In this study it has been tried, to compare results and convergence rate of sensitivity analysis and conjugate gradient algorithms to reduce fuel consumption and increasing engine performance by optimizing the timing of opening and closing valves in XU7/L3 engine. In this study, considering the strength and accuracy of simulation GT-POWER software in researches on the internal combustion engine...
متن کاملOpening and Closing in Tandem.
This interest relates to the overlapping Venn diagrams that demonstrate substantial intersection between these 2 diseases. AS increases with increasing age; although its morbidity and mortality have been documented since seminal work in the 1950s and 1960s (2), within the past 15 years, interest has grown exponentially. This growth is based on factors including, among others, the following: 1) ...
متن کاملValue-and-Criterion Filters: A new filter structure based upon morphological opening and closing
In this paper, we introduce the value-and-criterion filter structure and give an example of a filter with the structure. The value-and-criterion filter structure is based on morphological opening (or closing), which is actually two filters applied sequentially: the first assigns values based on the original image values, and the second assigns values based on the results of the first. The value...
متن کاملMeasurement of Opening and Closing Angles of Aortic Valve Prostheses In Vivo Using Dual-Source Computed Tomography: Comparison with Those of Manufacturers' in 10 Different Types
OBJECTIVE The aims of this study were to compare opening and closing angles of normally functioning mechanical aortic valves measured on dual-source computed tomography (CT) with the manufacturers' values and to compare CT-measured opening angles according to valve function. MATERIALS AND METHODS A total of 140 patients with 10 different types of mechanical aortic valves, who underwent dual-s...
