Congenital cardiomyopathy and pulmonary hypertension: another fatal variant of cytochrome-c oxidase deficiency

J Inherit Metab Dis. 2004;27(6):735-9. doi: 10.1023/B:BOLI.0000045711.89888.5e.

Abstract

Biventricular hypertrophy was noted at 24 weeks' gestation in a fetus with isolated cytochrome-c oxidase (COX) deficiency. Shock, caused by hypertrophic cardiomyopathy and severe pulmonary hypertension, led to the patient's death on day 6. His phenotype defines a new lethal variant of COX deficiency characterized by prenatal-onset cardiopulmonary pathophysiology.
