How serious valvular heart disease is depends on the type of valvular problem as well as on how far the problem has progressed. For people with advanced valvular heart disease, treatments such as surgery to repair or replace the damaged valve may be required.
On the other hand, people with mild valvular heart disease may not need any treatment at all and may notice no symptoms. People with mild valvular disease who practice preventive measures, such as living a healthy lifestyle, may never need treatment.
Some congenital valvular heart disease is serious, and some is not. While some congenital heart defects are life-threatening, they can be treated, and many people with such conditions are currently living fulfilling lives.
