This course will cover the hemodynamic significance of persistent fetal circulation, including patent foramen ovale (PFO) and patent ductus arteriosus (PDA). Starting with a brief explanation of fetal circulation followed by a explanation of outcomes as a result of this abnormal circulation as well as corrective options.
Persistent fetal circulation refers to abnormal heart circulation if the fetal heart shunts remain open after birth. This course will start with a recap of fetal circulation followed by a review of the outcomes of this persistent fetal circulation as well as corrective options.
The objective of this course is to provide the reader with the information needed to correctly identify a patent foramen ovale (PFO) and patent ductus arteriosus (PDA) on an echocardiogram. A PDA is considered to be the most common extracardiac shunt. With the finding of a PDA reported in 5-10% of all recorded congenital heart disease patients.
