Radiology of homograft aortic valves.
A consecutive series of 93 patients had homograft.aortic valve replacement at Green Lane Hospital over a six-month period. Except for 12 assessed at one or two months, the 85 survivors were examined at three months and the clinical degree of aortic incompetence was recorded. Thirty-four of the patients did not proceed to aortography for reasons unrelated to the state of the homograft valve. Fif...
متن کاملHomograft valves: is degeneration inevitable?
Since the first successful sub-coronary insertion (Ross 1962), the homograft aortic valve has been the favourite amongst many rypes of mechanicai or biological cardiac vaive repiacements ar the National Heart Hospital. Recent srudies on long rerm patient survivai afrer homograft insertion have reveaied excelient results (Bodnar er ai 1979), surpassed oniy by the autotranspianted puimonary valve...
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...
متن کاملViability of fresh mitral homograft valves.
The present study was undertaken to measure and compare the viability of the mitral leaflet, chordae, and papillary muscle. The viability of the valves was assessed by autoradiography at regular intervals after sterilization and preservation in antibiotics and nutrient medium. The results showed different rates of decline in viability of the leaflet, muscle, and chordae of the mitral valves. Sl...
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...
