Aortic valve debridement by ultrasonic surgical aspirator in degenerative, aortic valve stenosis: follow-up with Doppler echocardiography.
OBJECTIVE Recently there has been an emphasis on reconstructing diseases native valves as an alternative to prosthetic valve replacement. Whereas; the surgical repair of aortic valve stenosis has been always problematic. This study was performed to estimate the clinical results after aortic valve debridement using ultrasonic energy. METHODS Between 1990-1994 26 patients underwent ultrasonic a...
متن کاملDoppler echocardiographic findings in tissue engineered aortic valve in a sheep model
Background: Heart valve diseases are considered a common disease in human and animals, and valve replacement is an option for treatment of valvular diseases. Objectives: In this study efficacy of a tissue engineered valve in thoracic aorta was evaluated with transthoracic echocardiography. Methods: This study was undertaken on 6 male sheep. Echocardiography was performed on all sheep 24 hours b...
متن کاملAortic events after isolated aortic valve replacement for bicuspid aortic valve root phenotype: echocardiographic follow-up study.
OBJECTIVES Various forms of bicuspid aortic valve (BAV) aortopathy exist, and the optimal treatment for the different subgroups is insufficiently defined. We aimed to analyse the risk of adverse aortic events after aortic valve replacement (AVR) for BAV insufficiency and concomitant mild-to-moderate dilatation of the aortic root (i.e. BAV root phenotype). METHODS A total of 56 consecutive pat...
متن کاملPrimary aortic valve replacement with cryopreserved aortic allograft: an echocardiographic follow-up study of 570 patients.
BACKGROUND Despite the many advantages of an aortic allograft valve (AAV) over a prosthetic aortic valve, its durability is suboptimal. The aims of the present study were to document characteristic features of AAV dysfunction and to investigate factors influencing the development of such dysfunction. METHODS AND RESULTS A group of 570 patients (mean age, 48+/-16 years) with a cryopreserved AA...
متن کاملA new ultrasonic process for a renewal of aortic valve decalcification
BACKGROUND Aortic valve decalcification by ultrasound was given up. We evaluated a new ultrasound microhandpiece (Dissectron Penstyle) to rehabilitate this alternative treatment. METHODS We used under magnifying lenses the ultrasound microhandpiece to decalcify 30 explanted aortic valves. In the cases with embedded calcifications the thin top of the probe could be introduced into the thicknes...
