A method of sterilizing and preserving fresh allograft heart valves.
The present study was undertaken to find an antibiotic mixture which would rapidly and completely sterilize a heavily contaminated allograft heart valve without reducing its viability. Two different antibiotic combinations were used; formula A was used for 66 valves and formula B for 60 valves. Viability of the valves was assessed by autoradiography and tissue culture, and was found to be simil...
متن کاملPregnancy Outcome with Intracytoplasmic Sperm Injection Method in a Woman with Prosthetic Heart Valves
There is an increased risk of thromboembolism, anticoagulant-related hemorrhage, fetal-wastage and congestive cardiac failure in pregnant women with mechanical heart valves. In order to have a good outcome, the care of such patients must necessarily be multidisciplinary and in a well- equipped centre with adequate support services .One such patient who had mechanical mitral and aortic valves re...
متن کاملCellular biology of cryopreserved allograft valves.
Although analyzing the precise mechanisms of cryopreserved allograft valve failure may be difficult due to a number of crucial reasons and the interrelationships between the overlapping mechanisms, there is some evidence that cryopreservation is currently the best method of storing allograft valves. The present review shows the basic cellular biology of cryopreserved allograft valves for long-t...
متن کاملViability Assessment of Allograft Valves by Autoradiography
Autoradiography using [(3)H]thymidine is a quantitative method to assess tissue viability. It has been found to be very useful in the organization of fresh aortic valve allograft banks. A brief description of the technique, as well as the marked difference in the active metabolism of fibro-blasts of valves placed in two storing solutions, is outlined.
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...
