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 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 کاملOpening and closing the metabolite gate.
O n any given day you turn over your body weight equivalent in ATP, the principal energy currency of the cell. Mitochondria, which are believed to arise from the capture of a bacterium by an ancestral eukaryotic host cell (1), regenerate ATP from ADP and inorganic phosphate through oxidative phosphorylation. These organelles, termed the powerhouse of eukaryotic cells, contain both an inner and ...
متن کاملOpening and closing characteristics of the aortic valve after valve-sparing procedures using a new aortic root conduit.
BACKGROUND The durability of aortic valve-sparing procedures is negatively affected by increased leaflet stress in the absence of normally shaped sinuses of Valsalva. We compared valve motion after remodeling procedures using a standard conduit and a specifically designed aortic root conduit. METHODS Echocardiographic studies of the aortic valve dynamics were performed in 14 patients after re...
متن کاملEfficient Dilation, Erosion, Opening and Closing Algorithms
We propose an efficient and deterministic algorithm for computing the one dimensional dilation and erosion (max and min) sliding window filters. For a p-element sliding window, our algorithm computes the 1D filter using 1:5+o(1) comparisons per sample point. Our algorithm constitutes a deterministic improvement over the best previously known such algorithm, independently developed by van Herk [...
