How often do?congenital heart disease present as?heart failure?

Rarely in utero.: Even severe fetal cardiac defects rarely cause fetal hydrops or heart failure. On the other hand, many severe defects can present as florid cardiac failure in the nursery or the first few days/weeks of life and prompt expert care is mandatory.

Rare: A congenital defect to 'present' for the first time as heart failure, would likely be in the very young infant. Undiagnosed congenital disease which presents in this way, previously unknown, is quite rare.
