My daughter was born at 33 weeks with a suspicion of Mosaic downs syndrome. She had pneumonia shortly after birth. An echo cardiogram was performed at 3 weeks and result show an asd of 0.64cm ostrium primum ASD with intracardiac shunt. She was placed on lasix, captoprine and aldactone anti failure drugs. The echo was repeated after 3 months and the result remains the same. Is surgery required for such and how soon will it be advisable for correction surgery. And is their a possibility of closure to the hole in the heart and how long will she need to be on medication.
