Ventricular septal defect is usually symptomless at birth. It is common in patients with a congenital atrial septal aneurysm (ASA). This is known as a "patent foramen ovale", an atrial septal defect. The tricuspid valve usually has three leaflets, named the anterior, posterior, and septal leaflets. The anterior ethmoidal artery also helps to supply the lower septal cartilage. The septum pellucidum is often confused with the septal nuclei. Generally speaking anterior septal perforations are more bothersome and symptomatic. Meanwhile, Onler informs her about one of her children having ventricular septal defect. The interatrial septum can be divided into five septal zones. Of all of the congenital heart defects septal defects are the most common. The thicker left posterior fascicle bifurcates, with one fascicle being in the septal aspect. The nasal cartilages are the septal, lateral, major alar, and minor alar cartilages. A minor surgical procedure known as septoplasty can cure symptoms related to septal deviations. The three types of nephridia are&colon; integumentary, septal, and pharyngeal. They join with the septal cartilage at a junction known as the rhinion.
