  2. Ventricular septal defect - Wikipedia

    en.wikipedia.org/wiki/Ventricular_septal_defect

    Echocardiographic image of a moderate ventricular septal defect in the mid-muscular part of the septum. The trace in the lower left shows the flow during one complete cardiac cycle and the red mark the time in the cardiac cycle that the image was captured. Colours are used to represent the velocity of the blood.

  3. Tetralogy of Fallot - Wikipedia

    en.wikipedia.org/wiki/Tetralogy_of_Fallot

    The aortic root can be displaced toward the front (anteriorly) or directly above the septal defect, but it is always abnormally located to the right of the root of the pulmonary artery. The degree of override is extremely variable, with 5–95% of the valve being connected to the right ventricle. [41] Ventricular septal defect (VSD)

  4. Congenital heart defect - Wikipedia

    en.wikipedia.org/wiki/Congenital_heart_defect

    Defects in the interatrial septum or the interventricular septum allow blood to flow from the left side of the heart to the right, reducing the heart's efficiency. [47] Ventricular septal defects are collectively the most common type of CHD, [48] although approximately 30% of adults have a type of atrial septal defect called probe patent ...

  5. Cardiac shunt - Wikipedia

    en.wikipedia.org/wiki/Cardiac_shunt

    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]

    en.wikipedia.org/.../Ventricular_septal_defect

    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. Voila—two separate chambers.

  7. Transposition of the great vessels - Wikipedia

    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 ...

  8. Right-to-left shunt - Wikipedia

    en.wikipedia.org/wiki/Right-to-left_shunt

    Right ventricular hypertrophy (thickening of the muscular walls of the right ventricle, this is a result of the increased amount of work the heart has to do) Ventricular septal defect (a hole exists in the septum that divides the left and right ventricles)

  9. Atrioventricular septal defect - Wikipedia

    en.wikipedia.org/wiki/Atrioventricular_septal_defect

    Treatment is surgical and involves closure of the atrial and ventricular septal defects and restoration of a competent left AV valve as far as is possible. Open surgical procedures require a heart-lung machine and are done with a median sternotomy. Surgical mortality for uncomplicated ostium primum defects in experienced centers is 2%; for ...
