What does the interventricular do?
The interventricular septum separates the ventricles and allows for proper blood flow through the heart: from the right atrium through the tricuspid valve to the right ventricle to the lungs, back to the left atrium, followed by the left ventricle through the mitral valve.
What happens in ventricular septal defect?
A ventricular septal defect happens during pregnancy if the wall that forms between the two ventricles does not fully develop, leaving a hole. A ventricular septal defect is one type of congenital heart defect. Congenital means present at birth.
What causes ventricular septal defect in babies?
The most common cause of a VSD is a congenital heart defect, which is a defect from birth. Some people are born with holes already present in their heart. They may cause no symptoms and take years to diagnose. A rare cause of a VSD is severe blunt trauma to the chest.
What is the function of epicardium?
The epicardium comprises part of the pericardium, forming the visceral portion of the serous layer. The epicardium serves many functions, including protecting the heart, producing factors that help the cardiac cells properly develop, and ensuring proper response to cardiac cell injury.
What is interventricular septum?
The interventricular septum separates the left ventricle and the right ventricle. It is muscular at the apex and tapers to a membranous portion at the heart base near the origin of the aorta. Septal defects may occur in any area of the septum, but are most commonly located in the membranous portion.
What is difference between pericardium and epicardium?
Anatomy. The pericardium is a dual-layered structure enveloping the heart and proximal great vessels. It consists of an inner visceral pericardium (also called the epicardium when in contact with the myocardium), and an outer parietal pericardium, composed of layers of collagen fibrils and elastin fibers.
Where is the interventricular septum?
Interventricular Septum | Atlas of Human Cardiac Anatomy. Location: Medial wall of the left ventricle. This is the wall that borders septum between the left and right ventricle.
Do babies with VSD need surgery?
Healthcare providers often do the surgery in infants or children. Sometimes adults also need this type of repair if their VSD was not found during childhood. Although surgery is still the standard of care, a minimally invasive procedure using cardiac catheterization may be an option to fix the VSD for some children.
