Ventricular septal defect is curable but can it happen at the age of 17?if vsd is carried on for 17 years how serious would the condition be?

Rare: It would be rare to acquire a vsd at age 17. It could happen in the setting of trauma or endocarditis. More likely, it was present from birth and not previously recognized which implies that it is small. An echocardiogram can determine the amount of blood shunted through it and whether it is hemodynamically signficant. The decision to repair it or not would hinge on these measurements.

Depends: If it is a large vsd - very bad. If it is tiny or small - no big deal - you can live forever without surgery.

Depends: This depends on the size of the vsd. Many people have extremely small vsds for which nothing needs to be done and they live normal length, happy lives. Larger vsds is a different story. Please provide more detailed information and discuss this with your cardiologist to better understand your prognosis.
