Ventricular Septal Defect

Ventricular Septal Defect

What is Ventricular septal defect (VSD) 
Ventricular septal defect (VSD) is a flaw in the ventricular septum, the wall dividing the right and left ventricles of the heart. The ventricular septum comprises of an inferior muscular and superior membranous portion and is largely innervated with conducting cardiomyocytes. The membranous part, which is close to the atrioventricular node, is most commonly affected in adults and elder children in the United States. It is also the kind that will most commonly require surgical interference, comprising over 80% of similar cases. Membranous ventricular septal defect are more common than muscular ventricular septal defects, and are the most common congenital cardiac anomaly. 

Success rate
Closures are successful in more than 9 out of 10 patients. The success rate in these surgeries is high and safe. 

Care after the procedure 
Depending on the location of the VSD, the child's paediatric cardiologist will examine the child periodically to look for uncommon problems, such as a leak in the aortic valve. Rarely, elder children with small VSDs may require surgery if they develop a leak in this heart's valve. After surgery to close a VSD, a paediatric cardiologist  will examine the child regularly. The cardiologist will ensure that the heart is working normally. The long-term outlook is good and usually no medicines or additional surgery are needed.
