Heart defects are of different types and this is not the place to go into their details. Suffice to say that timely diagnosis and treatment (usually surgery) can cure the child of his or her congenital heart defect (CHD). Modern diagnostic tests are highly advanced and new surgical techniques mean small babies can be cured of their problems. Indian hospitals and doctors now have necessary skills to treat our kids, there is no need to go abroad. There may be a minor residual scar but then kids often have scarred knees and elbows throughout their childhood. Financial aid is available as well for the needy.
The children go on to live perfectly normal healthy lives contributing actively to society, industry. No more medications are required. The only thing they have to be careful about is not to let their teeth fall prey to caries. If this does happen timely dental treatment is a must.
Madhubala is a famous Indian personality whose heart had a defect at birth but was not treated for a long time.
14 February is celebrated as World Congenital Heart Defects Day worldwide.
