Aortic valve allografts in sheep.
Some of the mechanical and biological problems surrounding the use of fresh allograft inverted aortic valves as mitral valve substitutes are described. Certain aspects of the problem have been studied expzrimentally. In three sheep 'fresh' aortic valve allografts were-inserted, using cardio-pulmonary bypass, into the main pulmonary artery, and were observed from 5 to 7 months after operation. T...
متن کاملHistopathology of "fresh" human aortic valve allografts.
Gavin, J. B., Barratt-Boyes, B. G., Hitchcock, G. C., and Herdson, P. B. (1973). Thorax, 28, 482-487. Histopathology of 'fresh' human aortic valve allografts. Six aortic valve allografts were studied histologically after having functioned in patients as aortic valve replacements for 14 to 442 weeks. The grafts initially had been collected under sterile conditions from cadavers and stored in Han...
متن کاملMitral valve replacement with glutaraldehyde preserved aortic allografts.
OBJECTIVE To present long-term results after mitral valve replacement with stent mounted glutaraldehyde preserved aortic allografts in patients older than 15 years. The clinical support for this study was to combine the glutaraldehyde technique of biological tissue preservation with the advantages of allografts when compared to xenografts. This was demonstrated in previous studies using other m...
متن کاملClinical Outcome of Aortic Root Replacement With Cryopreserved Aortic Valve Allografts
Cryopreserved heart and vascular allografts are major prostheses of choice in cardiac surgery today, used in variety of treatment situations. Right and left ventricular outflow tract reconstruction in congenital heart diseases, cases of infective endocarditis, mitral valve plasty, and aortic aneurysm of infective etiology are the major indications for allograft use. Saphenous vein grafts with s...
متن کاملA rare case of prosthetic aortic valve endocarditis complicated with multiple fistula to peri aortic structure
Multiple aorto-cardiac cavity communications is very rare but important complication of prosthetic aortic valve endocarditis. The case below illustrates multiple aorto-cardiac cavity fistula formation following prostethic aortic valve endocarditis presented with slowly progressive symptoms of heart failure. A brief review of surgical reconstruction and the existing literature are presented, i...
