Truncus arteriosus communis is a congenital heart malformation, which is usually repaired in the neonatal period or early infancy. Although results of repair are good, there is long-term morbidity caused by reoperations mainly owing to right ventricle to pulmonary artery conduit exchange or stenosis at the pulmonary artery bifurcation as recently reported for Contegra conduits. We present a new...

OBJECTIVE The right ventricle in hypoplastic left heart syndrome (HLHS) works at systemic pressure and large volume loading before and after first stage palliation. There is a paucity of information regarding the intrinsic characteristics of the right ventricle in HLHS. We studied extra-cellular matrix composition, myocyte homeostasis and gene expression in right ventricular biopsies obtained f...

An infant with type 3c truncus arteriosus of Collett and Edwards is reported. In this anomaly, the left pulmonary artery arisesfrom the left lateral wall of the truncus and the right pulmonary artery originatesfrom a rght-sided ductus arteriosus. Only two reports of this malformation have been described previously. Precise anatomical diagnosis is ofimportance since some of these patients may ha...

now-a-days truncus arteriosus has been known as “common arterial trunk” (cat) and is an uncommon congenital cardiac defect presenting in about 1-3% congenital heart disease. environmental and genetic factors effects on incidence of cat and other conotruncal anomalies. the majority patients with cat and 22q11 deletion have other anomalies such as hypoplasia or aplasia of the thymus or parath...

Two-dimensional echocardiography was used to study a consecutive series of 13 infants with persistent truncus arteriosus. In all a single great artery with the long upward course characteristic of the aorta was shown. This great artery could be identified as a persistent truncus arteriosus by the recognition of a branch arising from its ascending part (10 out of 13) or of more than three semilu...
