Autograft or allograft aortic valve replacement in young adult patients with congenital aortic valve disease.
AIMS We analysed the outcome of young adults with congenital aortic valve disease who underwent allograft or autograft aortic valve or root replacement in our institution and evaluated whether there is a preference for either valve substitute. METHODS AND RESULTS Between 1987 and 2007, 169 consecutive patients with congenital aortic valve disease aged 16-55, participating in our ongoing prosp...
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 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 کاملTranscatheter Aortic Valve Replacement: A Review Article
Transcatheter aortic valve replacement (TAVR) is a novel therapeutic intervention for the replacement of severely stenotic aortic valves in high-risk patients for standard surgical procedures. Since the initial PARTNER trial results, use of TAVR has been on the rise each year. New delivery methods and different valves have been developed and modified in order to promote the minimally invasive p...
متن کاملValve-sparing aortic root replacement.
The aortic root has a unique 3-dimensional configuration and the distinctive function of supporting the aortic valve and blood vessels. The sinuses of Valsalva are crucial to create appropriate eddy currents that are important in initiating and coordinating aortic valve closure and promoting coronary artery blood flow. Most aneurysms in the aortic root are associated with degenerative changes i...
