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 ...
Heart sounds of a ventricular septal defect patient. The condition consists of atresia affecting the pulmonary valve and a hypoplastic right ventricular outflow tract. 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]
Eisenmenger syndrome or Eisenmenger's syndrome is defined as the process in which a long-standing left-to-right cardiac shunt caused by a congenital heart defect (typically by a ventricular septal defect, atrial septal defect, or less commonly, patent ductus arteriosus) causes pulmonary hypertension [1] [2] and eventual reversal of the shunt into a cyanotic right-to-left shunt.
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)
The symptoms/signs of pulmonary atresia that will occur in babies are consistent with cyanosis, some fatigue and some shortness of breath (eating may be a problem as well). [1] In the case of pulmonary atresia with ventricular septal defect, decreased pulmonary blood flow may cause associated defects such as: [5] Tricuspid atresia; Tetralogy of ...
The most typical form of APVS is a tetralogy of Fallot variant, [4] however, case studies have linked APVS to several different congenital cardiac syndromes, such as agenesis of ductus arteriosus, [5] persistent ductus arteriosus, [6] atrioventricular septal defect, [7] pulmonary branching abnormalities, [8] [9] transposition of the great arteries, [10] and type B interrupted aortic arch.

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 ...
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.
