The operation is performed under general anesthesia. The four pulmonary veins are reconnected to the left atrium, and any associated heart defects such as atrial septal defect, ventricular septal defect, patent foramen ovale, and/or patent ductus arteriosus are surgically closed. With obstruction, surgery should be undertaken urgently.
The most common congenital heart defects (CHDs) which cause shunting are atrial septal defects (ASD), patent foramen ovale (PFO), ventricular septal defects (VSD), and patent ductus arteriosi (PDA). In isolation, these defects may be asymptomatic , or they may produce symptoms which can range from mild to severe, and which can either have an ...
Atrial septal defect (ASD) is a congenital heart defect in which blood flows between the atria (upper chambers) of the heart.Some flow is a normal condition both pre-birth and immediately post-birth via the foramen ovale; however, when this does not naturally close after birth it is referred to as a patent (open) foramen ovale (PFO).
The VSD allows deoxygenated blood to flow from the right to left side of the heart. This blood bypasses the lungs. The lack of oxygenation in the pulmonary circulation results in cyanosis. Widely split fixed S 2 and systolic ejection murmur at the left upper sternal border Classic for a patent foramen ovale (PFO) or atrial septal defect (ASD).
The ventricular septal defect doesn't impede the in and outflowing of blood in the ventricular septum, which helps it form during fetal life. [ 3 ] [ 5 ] The spectrum of symptoms exhibited by children with this condition depends on the severity of the condition, while some barely show symptoms, others might develop complications such as ...
Ventricular septal defect is usually symptomless at birth. It usually manifests a few weeks after birth. [citation needed] VSD is an acyanotic congenital heart defect, aka a left-to-right shunt, so there are no signs of cyanosis in the early stage. However, an uncorrected VSD can increase pulmonary resistance leading to the reversal of the ...

The foramen ovale stays open because of the flow of blood from the right atrium to the left atrium. As the lungs expand, blood flows easily through the lungs and the membranous portion of the foramen ovale (the septum primum) flops over the muscular portion (the septum secundum). If the closure is incomplete, the result is a patent foramen ...
