Congenital malformations, especially those of the heart, are among the important causes of death in the neonatal period and in childhood. The factors of heredity and environment have been discussed by numerous workers, and there are many reports about the incidence of congenital cardiac defects in one or both of twins and of more than one case of congenital cardiac disease occurring in the same...
In avian and mammalian embryos, surgical ablation or severely reduced migration of the cardiac neural crest leads to a failure of outflow tract septation known as persistent truncus arteriosus (PTA) and leads to embryo lethality due partly to impaired excitation-contraction coupling stemming primarily from a reduction in the L-type Ca(2+) current (I(Ca),(L)). Decreased I(Ca,L) occurs without a ...
We report long-term outcome after one-stage, surgical repair, in a two months-old girl with persistent truncus arteriosus type I, II. The operation was carried out the remodeling of right ventricle, using swine bicuspid pulmonary prosthesis. Twenty-six years later, patient is excellent clinical condition, CF I (NYHA), normal peripheral oxygen saturation. Recent invasive and not imaging show: ab...
Persistent truncus arteriosus (PTA) is a rare conotruncal defect, defined as a single arterial vessel arising from the heart, which gives origin to the systemic, pulmonary and coronary circulations. It has an extremely poor prognosis and carries a high mortality rate during the early years of life unless surgically repaired. A few known cases have been reported of patients reaching maturity, an...
