Pulmonary Perfusion Changes Following Extracardiac Lateral Fontan and Bilateral Bidirectional Glenn Shunt in Hypoplastic Right Ventricle With Duplicated Superior Vena Cava

Abstract

The incidence of congenital heart disease requiring specialized care is 2.5 to 3 per 1000 live births with a prevalence of congenital heart disease of 81.4 per 10,000 live births. Total cavopulmonary or atriopulmonary connection, used for palliation of certain types of congenital heart disease, diverts flow from the vena cava or atrium directly into the pulmonary arteries. Altered anatomy in patients who have undergone this intervention may result in contrast and/or radiotracer localizing preferentially to a single lung leading to interpretation errors and redundant studies. Performing bilateral upper-extremity injections for this patient population may reduce such technical errors and redundant studies.

“…The incidence of congenital heart diseases is approximately 2.5–3/1000 live births, and the treatment modalities may include palliative procedures. [1] Glenn shunt procedure was first performed in 1958 by Dr. William Glenn, and it is still a useful stage in palliation for patients with single ventricle cardiac pathology. [2]…”
