Seven Additional Patients with Related Pulmonary Arterial Hypertension and Review of the Literature.

Pulmonary arterial hypertension (PAH) is an infrequent disorder characterized by high blood pressure in the pulmonary arteries. It may lead to premature death or the requirement for lung and/or heart transplantation. Genetics plays an important and increasing role in the diagnosis of PAH.

Timing of surgical repair of the stented aortic arch and coarctation in neonates.

We report a neonate with aortic arch hypoplasia and coarctation, in whom patency of the arterial duct could not be re-established and who was too ill to undergo primary surgical correction safely. This patient was treated in two stages: 1) angioplasty and stenting, 2) surgical correction. The safe period for surgical correction may be 2-3 weeks after angioplasty and stenting.
