Successful orthotopic heart transplantation in CPTII deficiency.

ABSTRACT: Carnitine palmitoyl transferase II (CPT II) catalyzes the release of activated long-chain fatty acids from acylcarnitines into mitochondria for subsequent fatty acid oxidation. Depending on residual enzyme activity, deficiency of this enzyme leads to a spectrum of symptoms from early onset hypoglycemia, hyperammonemia, cardiomyopathy and death to onset of recurrent rhabdomyolysis in adolescents and young adults. We present a case of successful orthotopic heart transplantation in a patient with severe infantile onset cardiomyopathy due to CPT II deficiency identified through newborn screening. Excellent cardiac function is preserved 12 years post-transplantation; however, the patient has developed intermittent episodes of hyperammonemia and rhabdomyolysis later in childhood and early adoles
