Autologous fascia lata for heart valve replacement.
To obviate the drawbacks of prosthetic devices and in search of a better substitute for diseased heart valves a technique of using autologous fascia lata grafts attached to a support frame was developed. The technique of preparing mounted fascia lata grafts is briefly outlined and their surgical implantation into the mitral, tricuspid, and aortic areas is described. Since April 1969, 83 fascial...
متن کاملDesign and construction of fascia lata aortic valve prostheses.
Current techniques for constructing fascia lata aortic valves result in a valve in which redundant cusp tissue is inadvertently incorporated in the proximal part of the cusp. This alters the flow character of the valve and produces a significant stenosis. An alternative technique, based on the normal anatomy of the aortic valve, is suggested which eliminates this fault. The technique is simple ...
متن کاملViability of autologous fascia lata in heart valve replacements.
A histological and radioautographic examination of 11 autologous fascia lata heart valves used in man is described. There was a significant decrease, exponential with time, in the number of fibroblasts per unit volume (P<0 001). The collagen bundles were grossly disorganized and separated, suggesting a breakdown of the cross-linkage in the tissue. Redundant connective tissue on the surface of t...
متن کاملAutologous fascia lata cardiac valve replacement.
Prosthetic cardiac valve replacement has been carried out at Brugmann University Hospital since 1962. In a series of 370 valvular replacements, operative and hospital deaths have attained a low rate (5%). The overall survival of 70% is comparable to that of most published series. Late thromboembolic complications, in spite of longterm anticoagulant therapy, remain the principal disadvantage of ...
متن کاملA fascia lata mitral valve based on the 'frustum' principle.
A newly designed strut-supported 'frustum' fascia lata valve has been described for replacement of the mitral valve. It offers the advantages of autologous tissue leaflets, ease of construction and insertion, central flow through an unobstructed mobile annulus, no ventricular outflow obstruction, and minimal intracardiac prosthetic material. Initial clinical trials which have been carried out s...
