Fontan completion in patient with pulmonary artery sling associated with hypoplastic left heart syndrome

Abstract

DISCUSSION Intracardiac lipomas usually present with encapsulation and have no potency of infiltrating adjoining tissues. In this case, the tumor had no encapsulation and theoretically was able to infiltrate the myocardium, which it did. Lipomas are very slow-growing tumors, and this case also shows the enormous adaptive capacity of a normal heart as the patient had no cardiac symptoms except the premature ventricular contractions with a huge tumor in the left ventricle.

In this case, the surgery was curative as the
