The Effect of Congenital Diaphragmatic Hernia on The Development of Left-Sided Heart Structures
Hernias occur in several forms most often affecting the abdomen other hernias include hiatus, incisional, and hernias. In addition the CDH can be associated with cardiac, gastrointestinal, genitourinary anomalies or with chromosomal aneuploidy such as trisomies. Multiple genetic factors along with environmental exposures and nutritional deficiencies have been proposed to be the possible etiologies for CDH. (1)
The hernia involves an abnormal exit of tissue or an organ, through the wall of the cavity in which it normally resides, it has different forms and causes. This report discussed the congenital hernia specifically the diaphragmatic type. In general, the diagnosis of congenital diaphragmatic hernia (CDH) can be made prenatally or after birth by imaging such as: ultra-sonographic, echocardiography, magnetic resonance imaging (MRI). In consequence to the herniation it leads to many complications in digestive and respiratory systems, the majority of the cases presenting with pulmonary hypoplasia and persistent pulmonary hypertension (PPHN). In addition to its effect on the development of the heart structures which is the aim of the report by focused on the left sided structures because left-sided CDH is more common due to the protective effect of the liver on the right preventing herniation.
