Percutaneous implantation of a balloon-expandable endoprosthesis for pulmonary artery stenosis: an experimental study.

Conventional therapy to treat peripheral pulmonary artery stenosis (surgery or balloon angioplasty) has been frustrating. Recently a variety of peripheral vascular stenoses, in which conventional approaches are disappointing, have become amenable to therapy with the use of a balloon-expandable endovascular stent. This experimental study was designed to assess the application of such a prosthesis in artificially created pulmonary artery stenoses.

Analysis of survival in patients with pulmonary atresia and intact ventricular septum treated surgically.

The epidemiology of 98 children who underwent surgical intervention for pulmonary atresia and intact ventricular septum is presented. Sixty-one (62.2%) of the children died.

Long-term results in neonates with pulmonary atresia and intact ventricular septum.

Our entire institutional experience with pulmonary atresia and intact ventricular septum (1965 through 1987) included 115 patients, 16 of whom died before surgical intervention. Fifty-six percent of surgical patients (n = 99) had angiographic evidence of right ventricle-coronary arterial connections. The early mortality in the surgical group was 27.
