The baseline level was 217 (82, 562) pg/mL, whereas the serial value was 261 (98, 715) pg/mL. The correlates of higher NT-proBNP levels were older age, atriopulmonary connection, atrial fibrillation, hepatorenal dysfunction, systemic ventricular dilation and systolic dysfunction, and higher Fontan pressures and pulmonary artery wedge pressure. Baseline and serial NT-proBNP levels were associated with death/transplant independent of anatomic indices, comorbidities, and hemodynamic indices.
