Research output: Contribution to journalArticlepeer-review


Homologous dura mater preserved in 40% glycerol was successfully used in various conditions requiring reconstruction. The use of dura mater for heart valve replacement was a logical consequence of this experience. A bicuspid heart valve supported by a thin walled stainless steel oval ring with two struts was constructed. The metallic ring was entirely covered by dacron velour fabric. The hemodynamic performance of this valve was examined in a pulse duplicator after implantation in dogs. No significant gradient through the valve was found in 25 different valves thus tested and experiments in 10 dogs confirmed the findings. Three different prostheses were implanted and tested in the mitral, tricuspid and aortic positions. Further study on the long term results of this type of heart valve in animals are planned, since the immediate results are encouraging.
