Attempts at further balloon dilation of the distal stenoses on the left were unsuccessful.
There was no gradient within the aorta, nor any discrete coronary arterial stenoses.
There were stenoses at the origin of the brachiocephalic artery.
Of the patients, 13 had no significant stenosis, while 25 had significant stenoses and, therefore, underwent balloon angioplasty.
One patient has discrete stenoses of the left anterior descending coronary artery and is scheduled for angioplasty.
This stent procedure may be applicable to small infants with branch pulmonary artery stenoses, obviating the need for early surgical or balloon angioplasty techniques.
All the segmental stenoses appeared within 7 years of the onset of the disease.
Surgical reconstruction of such stenoses, carries the same risk of (re)stenosis.
