pubmed-article:1087814 | pubmed:abstractText | The histological study of the conduction system has been done in a case of "straddling tricuspid valve". The main anomalies observed were an AV node located more anteriorly but at the left of the posterior interventricular septum and an hypertrophic bifasicular right bundle branch with an unusual anterior radiation. These morphological features allow to discuss the embryology of the conduction system and of the interventricular septum in that congenital cardiopathy. | lld:pubmed |
