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 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 کاملValve-preserving surgery on the bicuspid aortic valve.
Valve repair has emerged as an important intervention for the management of bicuspid aortic valve disease. This systematic review aims to assess the safety, efficacy and durability of bicuspid aortic valve repair. Initial searches yielded 682 abstracts, reduced by de-duplication to 370, of which 56 full papers were accessed and 30 met the inclusion criteria. Overall, 163 unique outcomes for bic...
متن کاملHealth-Related Quality of Life after Valve Replacement Surgery
Background: Heart valve disease gradually increases the pressure in the heart chambers and impairs heart pumping. It influences on quality of life due to low output, disability, fear, amnesia, anxiety, and depression. Although most of signs and symptoms in patients with heart valve diseases may significantly decrease after valve replacement surgery, there is limited information about the impact...
متن کاملSurgery of the Aortic Valve.
ESSENTIALLY all forms of aortic-valve disease can now be repaired or relieved by surgical techniques. In spite of this high degree of attainment, much remains to be accomplished in the evolution of improved techniques and materials and in the evaluation of the adequacy of these methods. The early operative result, the long-standing permanence of the correction, and the durability of prosthetic ...
