Congenital bicuspid aortic valves associated with coarctation of the aorta in children.
The 15-year experience of the cardiac clinic at this hospital from 1953 to 1967, with 429 children under 14 years of age with coarctation, was reviewed. The aortic valves of 119 available post-mortem specimens were re-examined, and the incidence of bicuspid valves and valvar stenosis determined. This necropsy incidence was then compared with the clinical incidence of aortic valvar disease in ch...
متن کاملAortic valve replacement with homograft and autograft valves. Performance of 615 valves over 15 years.
Homograft valve replacement of the diseased aortic valve with a homologous aortic valve inserted in the sub-coronary position was first performed in July 1962 (Ross 1962). The procedure of transferring the patients autologous pulmonary valve to the aortic position has been used since 1967 (Ross 1967). The long term performance of homograft vaives has not been regarded as satis facrory in some c...
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 کاملAortic valvular stenosis with coarctation of the aorta, with special reference to the development of aortic stenosis upon congenital bicuspid valves.
The combination of coarctation of the aorta and aortic valvular stenosis is not well known, although the association of coarctation with aortic incompetence is generally recognized and usually attributed to an incompetent bicuspid aortic valve. Abbot (1928), in her review of coarctation, did not discuss its association with aortic valvular stenosis. However, she reported four cases of sub-aorti...
متن کاملPost-mortem shrinkage of homograft aortic valves.
Experience has shown that some frame-mounted homograft aortic valves, although competent immediately after mounting, are incompetent when subsequently presented for surgical use. Retraction and shrinkage of the cusps appears to be the cause of this change. Clinical and experimental studies have shown that shrinkage of homograft aortic valves occurs over an approximately five-day period after de...
