Brief Summary:
It is known that the foramen ovale closes in most infants during the first 6 months of life, however, most of the important papers in the field concentrated on observing infants with murmurs and following those with patent foramen ovale by echocardiography until 6-24 months. The purpose of this study is to observe the natural profile of closure of the foramen ovale and ductus arteriosus for the first 36 hours after birth. This understanding may help to avoid unnecessary treatment and exams for newborns with findings that are natural for their stage of development.

Condition or disease Intervention/treatment
Closure of the Foramen Ovale and Ductus Arteriosus Device: no interventions

Detailed Description:
We will observe the patency and size of foramen ovale five times within the first 36 hours of life. We will also describe the anatomy of the foramen ovale and the septum primum during this time. The direction of flow across the foramen ovale will also be observed. Other cardiac lesions will be checked for as well. We will measure the change in size of the pulmonary arteries and the closure of the ductus arteriosus.
