Abstract:
The pulmonary artery of unfixated human heart-lung specimens was banded by placing a Dacron tape around the artery and securing the tape with a 5.0 Prolene suture at selected circumferences. The banding was successfully dilated with a balloon catheter in 24 instances. The mean pressure necessary to burst the suture securing the tape was 2.4 atmospheres.
