16 babies of diabetic mothers (36%) who had an interventricular
septum thickness greater than normal on echocardiography (group 1) and 29 babies of diabetic mothers who had a normal septum thickness (64%) (group 2) were included in the study as study groups.
septal and posterior wall thickness was observed in late pregnancy of pregestational diabetic mothers.
Similarly  reported in mouse that ventricular septation was dependent on a single structure, interventricular
septum which had both muscular and mesenchymal components.
The principal ascending draining lymphatic vessel located in the interventricular
septum and later positioned near the left atrial appendage was constantly visible regardless of the method applied; however, in old monkeys this vessel could be sclerotic and highly beaded in appearance.
Muscle index of the myocardial bridge (MI) also had the highest average value (mean) in bridges located above the anterior interventricular
There were no papillary muscle in the right ventricle of the ostrich and the moderator band attaches directly to the ventral surface of muscular valve from interventricular
La localizacion auriculares rara, siendo mas frecuentes a nivel ventricular principalmente izquierdo, musculos papilares y ambos lados del septo interventricular
, (2,4,8,13) sitios en los cuales y dependiendo de su tamano podran obstruir tractos de entrada o salida que pueden comprometer el funcionamiento cardiaco como en los casos descritos por Narendra y col.
En el caso del paciente reportado, el diagnostico se realizo in utero por ecografia obstetrica, inicialmente, y confirmacion con ecocardiograma fetal, el cual evidencio la comunicacion interventricular
muscular apical pequena, con cortocircuito de derecha a izquierda y dilatacion de cavidades derechas hasta el tronco y las ramas pulmonares.
