Congenital Heart Disease

This section focuses on congenital heart disease that can be found in older children or adults.

Entities include:

  1. Atrial Septal Defect (ASD)
  2. Ventricular Septal Defect (VSD)
  3. Partial Anomalous Pulmonary Venous Return (PAPVR)
  4. Patent Ductus Arteriosus (PDA)
  5. Congenitally Corrected Transposition of the Great Arteries (CCTGA)

It is important to understand how these abnormalities affect blood flow to the pulmonic circulation and how it is measured with MRI.

With the first 3 entities, pulmonic blood flow is usually increased and in these patients Qp/Qs is greater than 1.

Patients with a PDA usually have increased pulmonary blood flow. In these patients, Qp/Qs is typically less than one, because of the where the measurements are usually made in MRI.

In isolated CCTGA, pulmonary blood flow is normal and Qp/Qs =1.
