Serial measurement of the N-terminal pro-brain natriuretic peptide (NT-proBNP) predicts poor outcome in a patient with congenitally corrected transposition of the great arteries (ccTGA).

The usefulness of natriuretic peptides to assess myocardial function in patients with a systemic morphological right ventricle is still unclear. In this report we describe the clinical course of a young woman with congenitally corrected transposition of the great arteries (ccTGA) who suffered from a progressive deterioration of myocardial function after child birth despite intensive medical treatment and additional cardiac resynchronization therapy. In this woman, serial measurement of NT-proBNP levels was related to the velocity time integral over the aortic valve and indicated worsening of the patient's haemodynamic status and finally death.
