Chapter 20, Problem 2CRCAQ

Summary Introduction

To review:

The more difficult and dangerous surgery on a child between closing a patent ductus arteriosus or closing a patent foramen ovale.

Introduction:

The ductus arteriosus and foramen ovale are important parts of the fetal circulatory system. During the fetal stage, there is a requirement of oxygen and nutrients for the growing embryo while dealing with the limitations of a poorly-developed pulmonary circuit at the same time. The development of these two structures helps the embryo receive blood in the fetal stage.
