The heart is enlarged for the age of the child. There is marked hypertrophy. The aorta arises from
right ventricle; the pulmonary artery arises from the left ventricle. A large high ventricular septal
defect is present.
This child showed cyanotic heart disease virtually from birth. In addition to the lesions
seen here, he had a patent inter-auricular septum and a patent ductus arteriosus. Investigations
showed pulmonary hypertension with pressures equal to those in the systemic system. The lesions
were inoperable, but child survived to age of thirteen when he died from a cerebral abscess. There
is no evidence of endocarditis in the specimen.
