If a child has a small hole in the heart called a muskular ventricular septal defect, does that need surgery.?

Maybe: Depending on the amount of symptoms it aortic root involvement. A vsd is the most common congenital heart defect and even in childhood many go on to close themselves not requiring surgery.

Usually not: A muscular ventricular septal defect (vsd) is a special type of vsd (there are many kinds). The vast majority of small muscular vsds require no treatment, and 90% close up by themselves by a year of age. Only large defects or those associated with other heart problems are likely to require surgery.

Rarely: Most of the muscular vsd's specially if small and single spontaneously close. Periodic echocardiographic follow up advised. Strict oral hygiene to lower risk of cavities or tooth abcess is advised as well as prophillactic antibioic therapy prior to oral instrumentation. A pediatric dentist and pediatric cardiologist advised.

It depends: A vsd only requires surgery if it's large enough or if it causes problems with the aortic valve or other adjacent structures.
