My baby was diagnosed with both atrial septal defect and forearm patent ovale. what is prognosis?

Depends.: If it is indeed only and ASD the prognosis is good. If there is a fetal syndrome the diagnosis is poorer. Genetic and cardiological studies are required before answering your question with any degree of accuracy.

Pretty good: Atrial septal Defect=hole between the upper chambers, Patent foramen ovale= normal opening between the upper chambers that usually closes after birth.The ASD can vary in size while the PFO is usually smaller. This defect may or may not produce symptoms. It is often closed on a non urgent basis before school age. Small ones can be closed through a catheter. The doc can be more specific.
