A ventricular septal defect (VSD) is a defect in the ventricular septum, the wall dividing the left and right ventricles of the heart. The extent of the opening may vary from pin size to complete absence of the ventricular septum, creating one common ventricle. The ventricular septum consists of an inferior muscular and superior membranous ...
A ventricular septal defect is when this lower wall—the ventricular septum—has a gap in it after development. The septum is formed during development as this muscular ridge of tissue grows upward from the apex, or the tip, and then fuses with a thinner membranous region coming down from the endocardial cushions.
Heart septal defect refers to a congenital heart defect [1] of one of the septa of the heart. Atrial septal defect; Atrioventricular septal defect; Ventricular septal defect; Although aortopulmonary septal defects are defects of the aorticopulmonary septum, which is not technically part of the heart, they are sometimes grouped with the heart ...
Symptoms may appear at birth or after birth. The severity of symptoms depends on the type of TGV, and the type and size of other heart defects that may be present (ventricular septal defect, atrial septal defect, or patent ductus arteriosus). Most babies with TGA have blue skin color (cyanosis) in the first hours or days of their lives, since ...
Atrial septal defect with left-to-right shunt. The left and right sides of the heart are named from a dorsal view, i.e., looking at the heart from the back or from the perspective of the person whose heart it is. There are four chambers in a heart: an atrium (upper) and a ventricle (lower) on both the left and right sides. [1]
Congenital heart defect; Other names: Congenital heart anomaly, congenital heart disease: The normal structure of the heart (left) in comparison to two common locations for a ventricular septal defect (right), the most common form of congenital heart defect [1] Specialty: Cardiology: Symptoms: Rapid breathing, bluish skin, poor weight gain ...
If the ventricular septal defect is smaller than the pulmonary valve, the surgeon will enlarge the defect. The surgeon then uses a patch, commonly made of bovine (cow) pericardium or the child's own tissue, to create a tunnel between the ventricular septal defect and the pulmonary valve. This allows for blood to flow from the left ventricle to ...
In most cases of tricuspid atresia, additional defects exist to allow exchange of blood between the loops of systematic circulation and pulmonary circulation, filling in the role of the missing atrioventricular connection. An atrial septal defect (ASD) must be present to fill the left atrium and the left ventricle with blood. [4]
